Cerebral blood flow during treatment for pulmonary hypertension. (1/51)

AIM: To determine if the haemodynamics of systemic and cerebral circulation are changed during treatment for persistent pulmonary hypertension of the newborn (PPHN). METHODS: Fifteen term newborn piglets with hypoxia induced pulmonary hypertension were randomly assigned either tolazoline infusion (Tz), hyperventilation alkalosis(HAT), and inhaled nitric oxide (iNO). Mean pulmonary arterial pressure (PAP), mean systemic arterial pressure (SAP), and cerebral blood flow volume (CBF) were measured. RESULTS: During hypoxic breathing, PAP increased significantly in all groups. After treatment PAP decreased significantly in all groups, but no significant difference was observed between groups. SAP decreased significantly only in the Tz group, and CBF reduced significantly only in the HAT group. On the other hand, iNO did not change SAP or CBF. CONCLUSION: Inhaled NO might be ideal for the resolution of pulmonary hypertension.  (+info)

Splanchnic hemodynamics and gut mucosal-arterial PCO(2) gradient during systemic hypocapnia. (2/51)

The effects of hypocapnia [arterial PCO(2) (Pa(CO(2))) 15 Torr] on splanchnic hemodynamics and gut mucosal-arterial P(CO(2)) were studied in seven anesthetized ventilated dogs. Ileal mucosal and serosal blood flow were estimated by using laser Doppler flowmetry, mucosal PCO(2) was measured continuously by using capnometric recirculating gas tonometry, and serosal surface PO(2) was assessed by using a polarographic electrode. Hypocapnia was induced by removal of dead space and was maintained for 45 min, followed by 45 min of eucapnia. Mean Pa(CO(2)) at baseline was 38.1 +/- 1.1 (SE) Torr and decreased to 13.8 +/- 1.3 Torr after removal of dead space. Cardiac output and portal blood flow decreased significantly with hypocapnia. Similarly, mucosal and serosal blood flow decreased by 15 +/- 4 and by 34 +/- 7%, respectively. Also, an increase in the mucosal-arterial PCO(2) gradient of 10.7 Torr and a reduction in serosal PO(2) of 30 Torr were observed with hypocapnia (P < 0.01 for both). Hypocapnia caused ileal mucosal and serosal hypoperfusion, with redistribution of flow favoring the mucosa, accompanied by increased PCO(2) gradient and diminished serosal PO(2).  (+info)

Impeding O(2) unloading in muscle delays oxygen uptake response to exercise onset in humans. (3/51)

We tested whether the leftward shift of the oxygen dissociation curve of hemoglobin with hyperpnea delays the oxygen uptake (VO(2)) response to the onset of exercise. Six male subjects performed cycle ergometer exercise at a work rate corresponding to 80% of the ventilatory threshold (VT) VO(2) of each individual after 3 min of 20-W cycling under eupnea [control (Con) trial]. A hyperpnea procedure (minute ventilation = 60 l/min) was undertaken for 2 min before and during 80% VT exercise in hypocapnia (Hypo) and normocapnia (Normo) trials. In the Normo trial, the inspired CO(2) fraction was 3% to prevent hypocapnia. The subjects completed two repetitions of each trial. To determine the kinetic variables of VO(2) and heart rate (HR) at the onset of exercise, a nonlinear least-squares fitting was applied to the data averaged from two repetitions by a monoexponential model. The end-tidal CO(2) partial pressure before the onset of exercise was significantly lower in the Hypo trial than in the Con and Normo trials (22 +/- 1 vs. 38 +/- 3 and 36 +/- 1 mmHg, respectively, P < 0.05). The time constant of VO(2) and HR was significantly longer in the Normo trial (28 +/- 7 and 39 +/- 18 s, respectively) than in the Con trial (21 +/- 7, 34 +/- 16 s, respectively, P < 0.05). The VO(2) time constant of the Hypo trial (37 +/- 12 s) was significantly longer than that of the Normo trial, although no significant difference in the HR time constant was seen (Hypo, 41 +/- 28 s). These findings suggested that respiratory alkalosis delayed the kinetics of oxygen diffusion in active muscle as a result of the leftward shift of the oxygen dissociation curve of hemoglobin. This supports an important role for hemoglobin-O(2) offloading in setting the VO(2) kinetics at exercise onset.  (+info)

Role of C5a in multiorgan failure during sepsis. (4/51)

In humans with sepsis, the onset of multiorgan failure (MOF), especially involving liver, lungs, and kidneys, is a well known complication that is associated with a high mortality rate. Our previous studies with the cecal ligation/puncture (CLP) model of sepsis in rats have revealed a C5a-induced defect in the respiratory burst of neutrophils. In the current CLP studies, MOF occurred during the first 48 h with development of liver dysfunction and pulmonary dysfunction (falling arterial partial pressure of O(2), rising partial pressure of CO(2)). In this model an early respiratory alkalosis developed, followed by a metabolic acidosis with increased levels of blood lactate. During these events, blood neutrophils lost their chemotactic responsiveness both to C5a and to the bacterial chemotaxin, fMLP. Neutrophil dysfunction was associated with virtually complete loss in binding of C5a, but binding of fMLP remained normal. If CLP animals were treated with anti-C5a, indicators of MOF and lactate acidosis were greatly attenuated. Under the same conditions, C5a binding to blood neutrophils remained intact; in tandem, in vitro chemotactic responses to C5a and fMLP were retained. These data suggest that, in the CLP model of sepsis, treatment with anti-C5a prevents development of MOF and the accompanying onset of blood neutrophil dysfunction. This may explain the protective effects of anti-C5a in the CLP model of sepsis.  (+info)

Enhanced temporal stability of cholinergic hippocampal gamma oscillations following respiratory alkalosis in vitro. (5/51)

The decrease in brain CO(2) partial pressure (pCO(2)) that takes place both during voluntary and during pathological hyperventilation is known to induce gross alterations in cortical functions that lead to subjective sensations and altered states of consciousness. The mechanisms that mediate the effects of the decrease in pCO(2) at the neuronal network level are largely unexplored. In the present work, the modulation of gamma oscillations by hypocapnia was studied in rat hippocampal slices. Field potential oscillations were induced by the cholinergic agonist carbachol under an N-methyl-D-aspartate (NMDA)-receptor blockade and were recorded in the dendritic layer of the CA3 region with parallel measurements of changes in interstitial and intraneuronal pH (pH(o) and pH(i), respectively). Hypocapnia from 5 to 1% CO(2) led to a stable monophasic increase of 0.5 and 0.2 units in pH(o) and pH(i), respectively. The mean oscillation frequency increased slightly but significantly from 32 to 34 Hz and the mean gamma-band amplitude (20 to 80 Hz) decreased by 20%. Hypocapnia induced a dramatic enhancement of the temporal stability of the oscillations, as was indicated by a two-fold increase in the exponential decay time constant fitted to the autocorrelogram. A rise in pH(i) evoked by the weak base trimethylamine (TriMA) was associated with a slight increase in oscillation frequency (37 to 39 Hz) and a decrease in amplitude (30%). Temporal stability, on the other hand, was decreased by TriMA, which suggests that its enhancement in 1% CO(2) was related to the rise in pH(o). In 1% CO(2), the decay-time constant of the evoked monosynaptic pyramidal inhibitory postsynaptic current (IPSC) was unaltered but its amplitude was enhanced. This increase in IPSC amplitude seems to significantly contribute to the enhancement of temporal stability because the enhancement was almost fully reversed by a low concentration of bicuculline. These results suggest that changes in brain pCO(2) can have a strong influence on the temporal modulation of gamma rhythms.  (+info)

Effects of respiratory acidosis and alkalosis on the distribution of cyanide into the rat brain. (6/51)

The aim of this study was to determine whether respiratory acidosis favors the cerebral distribution of cyanide, and conversely, if respiratory alkalosis limits its distribution. The pharmacokinetics of a nontoxic dose of cyanide were first studied in a group of 7 rats in order to determine the distribution phase. The pharmacokinetics were found to best fit a 3-compartment model with very rapid distribution (whole blood T(1/2)alpha = 21.6 +/- 3.3 s). Then the effects of the modulation of arterial pH on the distribution of a nontoxic dose of intravenously administered cyanide into the brains of rats were studied by means of the determination of the permeability-area product (PA). The modulation of arterial blood pH was performed by variation of arterial carbon dioxide tension (PaCO2) in 3 groups of 8 anesthetized mechanically ventilated rats. The mean arterial pH measured 20 min after the start of mechanical ventilation in the acidotic, physiologic, and alkalotic groups were 7.07 +/- 0.03, 7.41 +/- 0.01, and 7.58 +/- 0.01, respectively. The mean PAs in the acidotic, physiologic, and alkalotic groups, determined 30 s after the intravenous administration of cyanide, were 0.015 +/- 0.002, 0.011 +/- 0.001, and 0.008 +/- 0.001 s(-1), respectively (one-way ANOVA; p < 0.0087). At alkalotic pH the mean permeability-area product was 43% of that measured at acidotic pH. This effect of pH on the rapidity of cyanide distribution does not appear to be limited to specific areas of the brain. We conclude that modulation of arterial pH by altering PaCO2 may induce significant effects on the brain uptake of cyanide.  (+info)

Effects of hypercapnia and hypocapnia on [Ca2+]i mobilization in human pulmonary artery endothelial cells. (7/51)

The hydrogen ion is an important factor in the alteration of vascular tone in pulmonary circulation. Endothelial cells modulate vascular tone by producing vasoactive substances such as prostacyclin (PGI2) through a process depending on intracellular Ca2+ concentration ([Ca2+]i). We studied the influence of CO2-related pH changes on [Ca2+]i and PGI2 production in human pulmonary artery endothelial cells (HPAECs). Hypercapnic acidosis appreciably increased [Ca2+]i from 112 +/- 24 to 157 +/- 38 nmol/l. Intracellular acidification at a normal extracellular pH increased [Ca2+]i comparable to that observed during hypercapnic acidosis. The hypercapnia-induced increase in [Ca2+]i was unchanged by the removal of Ca2+ from the extracellular medium or by the depletion of thapsigargin-sensitive intracellular Ca2+ stores. Hypercapnic acidosis may thus release Ca2+ from pH-sensitive but thapsigargin-insensitive intracellular Ca2+ stores. Hypocapnic alkalosis caused a fivefold increase in [Ca2+]i compared with hypercapnic acidosis. Intracellular alkalinization at a normal extracellular pH did not affect [Ca2+]i. The hypocapnia-evoked increase in [Ca2+]i was decreased from 242 +/- 56 to 50 +/- 32 nmol/l by the removal of extracellular Ca2+. The main mechanism affecting the hypocapnia-dependent [Ca2+]i increase was thought to be the augmented influx of extracellular Ca2+ mediated by extracellular alkalosis. Hypercapnic acidosis caused little change in PGI2 production, but hypocapnic alkalosis increased it markedly. In conclusion, both hypercapnic acidosis and hypocapnic alkalosis increase [Ca2+]i in HPAECs, but the mechanisms and pathophysiological significance of these increases may differ qualitatively.  (+info)

Total weak acid concentration and effective dissociation constant of nonvolatile buffers in human plasma. (8/51)

The strong ion approach provides a quantitative physicochemical method for describing the mechanism for an acid-base disturbance. The approach requires species-specific values for the total concentration of plasma nonvolatile buffers (A(tot)) and the effective dissociation constant for plasma nonvolatile buffers (K(a)), but these values have not been determined for human plasma. Accordingly, the purpose of this study was to calculate accurate A(tot) and K(a) values using data obtained from in vitro strong ion titration and CO(2) tonometry. The calculated values for A(tot) (24.1 mmol/l) and K(a) (1.05 x 10(-7)) were significantly (P < 0.05) different from the experimentally determined values for horse plasma and differed from the empirically assumed values for human plasma (A(tot) = 19.0 meq/l and K(a) = 3.0 x 10(-7)). The derivatives of pH with respect to the three independent variables [strong ion difference (SID), PCO(2), and A(tot)] of the strong ion approach were calculated as follows: dpH/dSID(+) = [1 + 10(pK(a)-pH)](2)/(2.303 x [SPCO(2)10(pH-pK'(1)[1 + 10(pK(a)-pH](2) + A(tot)10(pK(a)-PH]]; dpH/dPCO(2) = S10(-pK'(1)/[2.303[A(tot)10(pH)(10(pH + 10(pK(a))(-2) - SID(+)10(-pH)]], dpH/dA(tot) = -1/[2.303[SPCO(2)10(pH-pK'(1) + SID(+)10(pK(a)-pH)]], where S is solubility of CO(2) in plasma. The derivatives provide a useful method for calculating the effect of independent changes in SID(+), PCO(2), and A(tot) on plasma pH. The calculated values for A(tot) and K(a) should facilitate application of the strong ion approach to acid-base disturbances in humans.  (+info)

Respiratory alkaloses can be compensated by the actions of the kidneys which serve to realign the bicarbonate buffer Henderson-Hasselbalch Equation over a period of several days. As described in Renal Response to Acid-Base Imbalance, the kidneys respond to alkalosis by excreting bicarbonate, thus reducing the ECF bicarbonate concentration. The decreased bicarbonate concentration realigns the Henderson-Hasselbalch Equation for the bicarbonate buffer and thus largely corrects the ECF pH. Consequently, a renally-compensated respiratory alkalosis is characterized by decreased levels of PaCO2 (caused by the primary ventilatory disturbance) as well as decreased levels of ECF bicarbonate (caused by the renal compensation). However, it is important to point out that renal compensation cannot completely correct the ECF pH and thus the ECF will still remain slightly alkalotic even after compensation ...
The mechanism of respiratory alkalosis generally occurs when some stimulus makes a person hyperventilate. The increased breathing produces increased alveolar respiration, expelling CO2 from the circulation. This alters the dynamic chemical equilibrium of carbon dioxide in the circulatory system. Circulating hydrogen ions and bicarbonate are shifted through the carbonic acid (H2CO3) intermediate to make more CO2 via the enzyme carbonic anhydrase according to the following reaction: ...
Although the acid-base status can be variable -- depending on the degree of overdose, and the point in the timeline after ingestion at which the patient is seen -- the most common chemical results seen are a metabolic acidosis + respiratory alkalosis . This is seen as an acidemia with a lower than expected C02 compensation. The respiratory alkalosis occurs because of salicylates direct stimulation on the respiratory centers. One should note that the respiratory alkalosis can be masked by other medications that may have been ingested at the same time, such as benzodiazepines, and tricyclic antidepressants. The metabolic acidosis comes from acetylsalicylic acid, salicylic acid, and the production of lactic acid, free fatty acids, and amino acids ...
Hyperventilation occurs when the rate and quantity of alveolar ventilation of carbon dioxide exceed the bodys production of carbon dioxide. Hyperventilation can be voluntary or involuntary.. When breathing is excessive, more carbon dioxide will be removed from the bloodstream than the body can produce. This causes the concentration of carbon dioxide in the bloodstream to fall and produces a state known as hypocapnia. The body normally attempts to compensate for this metabolically.. If excess ventilation cannot be compensated metabolically, it will lead to a rise in blood PH. This rise in blood pH is known as respiratory alkalosis. When hyperventilation leads to respiratory alkalosis, it may cause a number of physical symptoms: dizziness, tingling in the lips, agitation, confusion, feeling they cannot breathe, headache, weakness, fainting and seizures. In extreme cases, it can cause spasms flapping and contraction of the hands and feet and is sometimes referred to as claw hands.. Swimmers ...
Before induction of anesthesia, electrocardiographic leads were attached and continuous ST segment analysis of lead II and V5(60 ms after the j-point; Sirecust 1281; Siemens, Erlangen, Germany) was initiated. A 20-gauge catheter was placed in the radial artery to measure mean arterial pressure and to collect blood samples. Anesthesia was induced with 2 [micro sign]g/kg sufentanil and 0.1 mg/kg pancuronium bromide. After tracheal intubation, patients were ventilated by a volume-controlled respirator (AV 1, Drager, Lubeck, Germany) with an inspiratory fraction of oxygen of 0.3. During the measurement period, anesthesia was maintained by a continuous infusion of sufentanil (3.5 [micro sign]g [middle dot] kg-1[middle dot] h-1). Body temperature was kept constant using warm covers. Subsequently, the following catheters were inserted: a flow-directed pulmonary artery catheter (Hands-off thermodilution catheter AH-0500; ARROW, Erding, Germany) via the left subclavian vein to measure mean pulmonary ...
The appearance of a severely tachypneic patient can prompt the urge to intubate. However, one must keep in mind that the organ of toxicity for aspirin is the brain. Aspirin has a pKa of 3.5 which means in acidic environments it is more likely to be non-ionized. This allows movement across membranes, including the blood-brain barrier. Aspirin causes a direct stimulation of the respiratory center inducing tachypnea. Frequently, salicylate-toxic patients will have a mixed metabolic acidosis with respiratory alkalosis. Intubation of these patients can remove the respiratory alkalosis component which causes blood pH to drop and allows more non-ionized aspirin to enter the brain [4]. Patients with salicylate toxicity may rapidly deteriorate or die if intubated because their minute ventilation on the ventilator often do not match their pre-intubation minute ventilation. ...

First, look at the pH; in this case it is alkalotic. You must now distinguish if this is respiratory, mixed, or metabolic. So pay attention to the pCO2 and the HCO3 and note that the HCO3 is normal but the pCO2 is low. The characteristic of respiratory alkalosis is increase in pH with decrease in pCO2. In the acute setting, note that HCO3 typically decreases by 2 mEq/L for every 10 mm Hg drop in pCO2. In chronic respiratory alkalosis, HCO3 typically increases by 4 mEq/L of HCO3 for every 10 mm Hg drop in pCO2. ...
Abstract. In cirrhotic patients, in addition to hepatocytes and Kuppfer cells dysfunction circulatory anatomic shunt and ventilation/perfusion (VA/ Q) ratio abnormalities can induce decrease in partial pressure of oxygen in arterial blood (PaO2), in oxygen saturation of hemoglobin (SaO2) as well as various acid-base disturbances. We studied 49 cases of liver cirrhosis (LC) with ascites compared to 50 normal controls. Causes were: posthepatic 37 (75.51%), alcoholic 7 (14.24%), cardiac 2 (4.08%), and cryptogenic 3 (6.12%). Complications were: upper gastrointestinal bleeding 24 (48.97), hepatic encephalopathy 20 (40.81%), gastritis 28 (57.14%), hepatoma 5 (10.2%), renal hepatic syndrome 2 (4.01%), HbsAg (+) 24 (48.97%), and hepatic pleural effusions 7 (14.28%). Average PaO2 and SaO2 were 75.2 mmHg and 94.5 mmHg, respectively, compared to 94.2 mmHg and 97.1 mmHg of the control group, respectively (p value in both PaO2 and SaO2 was p,0.01).

oxygen in the inspired gas in the lungs. This change leads in turn to less pressure driving oxygen diffusion from the alveoli and throughout the oxygen cascade. A normal initial struggle response to such an ascent includes increased ventilation, which is the cornerstone of acclimation. Hyperventilation may cause respiratory alkalosis and dehydration. Alkalosis may depress the ventilatory drive during sleep, with consequent periodic breathing and hypoxemia. During early acclimation, renal suppression of carbonic anhydrase and excretion of dilute alkaline urine combat alkalosis and tend to bring the pH of the blood to normal. Other physiologic changes during normal acclimation include increased sympathetic tone; increased ...
Step 1. This step is straightforward. Look at the pH. Is the blood acidemic or alkalemic? This is the primary disorder. Any compensation for a metabolic disturbance by the lungs or vice versa will not bring the pH back to normal. Step 2. Determine whether the primary disorder is respiratory or metabolic. This is accomplished by looking at the bicarbonate on the chemistry or the pCO2 on the ABG. In acidemia, low bicarbonate (, 24) and low pCO2 (, 40) suggests a metabolic acidosis. Alternatively, a high bicarbonate (, 24) and high pCO2 (, 40) suggests that the primary disorder is a respiratory one. The opposite is true for alkalemia. A patient with an elevated bicarbonate (, 24) and pCO2 (, 40) supports a metabolic alkalosis, while low bicarbonate (, 24) and low pCO2 (,40) supports a respiratory alkalosis. Step 3. The next question you would like to answer is whether or not the other body system (kidneys in a primary respiratory disorder or lungs in a primary metabolic disorder) are compensating ...
A public lecture by Philip Ainslie, Professor & Canada Research Chair in Cerebrovascular Physiology and Co-Director, Centre for Heart, Lung & Vascular Health, The University of British Columbia. Relative to its size, the brain is the most oxygen-dependent organ in the body, but many pathophysiological and environmental processes may either cause or result in an interruption to its oxygen supply. Arguably the most unique data in humans comes from free-divers and mountaineers, extreme athletes in whom the lowest oxygen tensions and greatest extremes of carbon dioxide have been recorded (from respiratory alkalosis in the mountaineer to acidosis in the free-diver). In this talk, with a focus on integration and punitive mechanism(s) of action, data will be highlighted to examine to what extent the brain likely contributes toward these athletes extraordinary abilities to survive in such harsh environments characterized by physiological extremes of hypoxemia, alkalosis, and acidosis helping define the ...
The major function of the respiratory system is gas exchange between the external environment and an organisms circulatory system. In humans and mammals, this exchange facilitates oxygenation of the blood with a concomitant removal of carbon dioxide and other gaseous metabolic wastes from the circulation. As gas exchange occurs, the acid-base balance of the body is maintained as part of homeostasis. If proper ventilation is not maintained, two opposing conditions could occur: respiratory acidosis, a life threatening condition, and respiratory alkalosis.. Upon inhalation, gas exchange occurs at the alveoli, the tiny sacs which are the basic functional component of the lungs. The alveolar walls are extremely thin (approx. 0.2 micrometres). These walls are composed of a single layer of epithelial cells (type I and type II epithelial cells) in close proximity to the pulmonary capillaries which are composed of a single layer of endothelial cells. The close proximity of these two cell types allows ...
The most likely diagnosis is asthma. Asthma is a reversible airway obstruction secondary to bronchial hyperreactivity, airway inflammation, mucous plugging and smooth muscle hypertrophy. Patients often present with cough, episodic wheezing, dyspnea, and chest tightness. Symptoms often worsen at night or early in the morning. Physical exam reveals wheezing, prolonged expiratory duration (decreased inspiratory to expiratory ratio), accessory muscle use, tachypnea, tachycardia, decreased breath sounds (late sign), decreased oxygen saturation (late sign), hyperresonance and possible pulsus paradoxus. Arterial blood gases demonstrate mild hypoxia and respiratory alkalosis. Normalizing PCO2, respiratory acidosis and more severe hypoxia in an acute exacerbation warrant close observation as they may indicate fatigue and impending respiratory failure. Spirometry may show a decreased FEV1/FVC ratio. Eosinophilia may be seen on a CBC while a CXR shows signs of hyperinflation. Asthma can be definitively ...

Zonisamide causes hyperchloremic, non-anion gap, metabolic acidosis (i.e., decreased serum bicarbonate below the normal reference range in the absence of chronic respiratory alkalosis) (see PRECAUTIONS, Laboratory Tests subsection). This metabolic acidosis is caused by renal bicarbonate loss due to the inhibitory effect of zonisamide on carbonic anhydrase.. Generally, zonisamide-induced metabolic acidosis occurs early in treatment, but it can develop at any time during treatment. Metabolic acidosis generally appears to be dose-dependent and can occur at doses as low as 25 mg daily.. Conditions or therapies that predispose to acidosis (such as renal disease, severe respiratory disorders, status epilepticus, diarrhea, ketogenic diet, or specific drugs) may be additive to the bicarbonate lowering effects of zonisamide.. Some manifestations of acute or chronic metabolic acidosis include hyperventilation, nonspecific symptoms such as fatigue and anorexia, or more severe sequelae including cardiac ...

Diuretic use is the most common cause of phosphorus loss through the kidneys. Thiazides, loop diuretics, and acetazolamide are the diuretics that most commonly cause hypophosphatemia.. The second most common cause is diabetic ketoacidosis (DKA) in diabetic patients who have poorly controlled blood glucose levels. In DKA, high glucose levels induce an osmotic diuresis. This results in a significant loss of phosphorus from the kidneys. Ethanol affects phosphorus reabsorption in the kidneys so that more phosphorus is excreted in urine.. A buildup of PTH, which occurs with hyperparathyroidism and hypocalcemia, also leads to hypophosphatemia because PTH stimulates the kidneys to excrete phosphate.. Finally, hypophosphatemia occurs in patients who have extensive burns. Although the mechanism is unclear, the condition seems to occur in response to the extensive diuresis of salt and water that typically occurs during the first 2 to 4 days after a burn injury. Respiratory alkalosis and carbohydrate ...
A 47-year-old woman was admitted to the cardiac surgery ICU with severe end stage cardiomyopathy following placement of RVAD and LVAD for biventricular cardiac support as a bridge to heart transplantation. The patient had a previous implanted permanent internal pacemaker and transthoracic pacing wires placed at the time of her current surgery. During the cardiothoracic procedure it was found that the internal pacer wires had been transected, necessitating the need for external pacing. Four days following a complicated postoperative course, while the patient was heavily sedated on high dose sedation/analgesia and multiple pressors, an arterial blood gas revealed a respiratory alkalosis (pH 7.61, PaCO2 23 mm Hg) secondary to hyperventilation. Ventilator settings using the Galileo ventilator (Hamilton, Bonaduz, Switzerland) at the time were pressure control continuous mandatory ventilation mode, pressure control setting of 25 cm H2O, target exhaled tidal volume 300 mL (8.8 mL/kg predicted body ...
An explanation of our approach which does not use technical language can be found on the Understanding Your Symptoms tab, which also has a page explaining the words which we use.. There is substantial evidence that patients with medically unexplained symptoms (MUS) and functional somatic syndromes (FSS) suffer from the physiological effects of sustained psychosocial stress. Within the loss of homeostasis, hyper-arousal creates a widespread imbalance affecting limbic system self-regulation, the hypothalamo-pituitary-adrenal (HPA) axis (creating a sympathetic/parasympathetic imbalance), and immune competence. Breath regulation may also be disturbed, resulting in hyperventilation and subsequent respiratory alkalosis and reduction in transfer of oxygen to the brain and tissues. The patient will find it difficult to release their symptoms whilst there is a sustained focus of distress within a persistent state of fight, flight, freeze and fold response. However, explaining such symptoms to patients ...

Given the fundamental role that the kidney has in the maintenance of homeostasis, it is not uncommon to observe the appearance of water and electrolytic disorders in patients who suffer from chronic terminal renal failure. In the case of patients undergoing peritoneal dialysis, due to the particular aspects which are characteristic of this dialytic modality, there is a series of hydro-electrolytic problems which are more frequently detected in this subgroup of patients: hydrosaline retention, hypokalemia, hypermagnesemia, and respiratory alkalosis. Regarding hydrosaline retention, it is observed when water and salt intake exceeds its urinary and/or dialytic excretion. The latter is observed when there is scarce ultrafiltration, be it due to an inadequate dialytic strategy or to stress of the peritoneal membrane. Concerning hypokalemia, it can be observed up to 30% of the peritoneal dialysis patients, originating from the effect of the released insulin due to the glucose absorbed from the ...

In large amounts, and especially over extended periods of time, caffeine can lead to a condition known as caffeinism.[62][63] Caffeinism usually combines caffeine dependency with a wide range of unpleasant physical and mental conditions including nervousness, irritability, anxiety, tremulousness, muscle twitching (hyperreflexia), insomnia, headaches, respiratory alkalosis[64] and heart palpitations.[65] Furthermore, because caffeine increases the production of stomach acid, high usage over time can lead to peptic ulcers, erosive esophagitis, and gastroesophageal reflux disease.[66] However, since both regular and decaffeinated coffees have been shown to stimulate the gastric mucosa and increase stomach acid secretion, caffeine is probably not the sole component of coffee responsible.[67 ...
This chapter focuses on the ways in which a changing CO2 concentration might alter the pH of a solution, particularly that of your precious bodily fluids. The physiological consequences of acidaemia and alkalaemia are discussed in dedicated chapters, as are the various effects of having an excessively high or precipitously low blood CO2 level (independent of pH changes). A chapter which summarises the bedside rules and equations used in the interpretation of blood gases is also available as a brief overview of the empirically derived formulae which describe acute and chronic compensation for acidosis and alkalosis.

N2 - Respiratory acid-base status has recently been shown to affect pulmonary vascular resistance (PVR) in adults following cardiac surgery. The purpose of this study was to examine what influence cardiopulmonary bypass has on the pulmonary vascular response to changes in respiratory acid-base status. Fifteen consecutive patients undergoing aortocoronary bypass were studied under general anesthesia both before and after cardiopulmonary bypass. Arterial PCO2 was manipulated by the addition of 5 percent carbon dioxide to the breathing circuit. Both before and after bypass, PVR increased significantly as PCO2 rose from 30 mm Hg to 50 mm Hg (p,0.05). The PVR returned ...

Metabolic Alkaloses can be compensated by the actions of the lungs which serve to realign the bicarbonate buffer Henderson-Hasselbalch Equation over a period of hours. As described in Respiratory Acid-Base Control, the lungs respond to alkalosis by decreasing alveolar ventilation, essentially a physiological hypoventilation, which in turn increases the partial pressure of arterial carbon dioxide (PaCO2). The increased PaCO2 realigns the Henderson-Hasselbalch Equation for the bicarbonate buffer and thus largely corrects the ECF pH. Consequently, a respiratory-compensated metabolic alkalosis is characterized by increased levels of ECF bicarbonate (caused by the primary metabolic disturbance) as well as increased levels of PaCO2 (caused by the respiratory compensation). More colloquially, the lungs compensate for the metabolic alkalosis by slowing Breathing Off of acid in the form of CO2, thus helping reduce ECF pH. However, it is important to point out that respiratory compensation cannot ...
Blood gas tests can be used in the diagnosis of a number of acidosis conditions such as lactic, metabolic, and respiratory acidosis, diabetic ketoacidosis, and also of respiratory alkalosis.[1] Particularly, umbilical cord blood gas analysis can give an indication of preceding fetal hypoxic stress. In combination with other clinical information, normal paired arterial and venous cord blood gas results can usually provide a robust defence against a suggestion that an infant had an intrapartum hypoxic‐ischaemic event.[2]. Abnormal results may be due to a wide range of diseases, including poisoning and trauma as well as lung, kidney, or metabolic diseases. Drug overdose and uncontrolled diabetes may be determined from abnormal results.[4] Head or neck injuries or other injuries that affect breathing can also lead to abnormal results.[1]. ...

A congenital diaphragmatic hernia (CDH) is an early developmental defect that results in the extrusion of intraabdominal organs (ie. stomach, small intestines, kidney, liver) into the thoracic cavity. This defect can be isolated or associated with multiple congenital abnormalities with cardiac anomalies being the most common. Ninety-percent of CDH are located in the posterolateral diaphragm (Bochdaleks hernia), 3/4 of which are left sided. Physiologic consequences of CDH include lung hypoplasia, pulmonary hypertension, and pulmonary arteriolar dysregulation/reactivity (Davis, et al). Historically, CDH was considered a surgical emergency. It was approached using aggressive hyperventilatory strategies with the goal of obtaining pulmonary vasodilation through hyperoxia and respiratory alkalosis. This strategy often used high peak inspiratory pressures, ventilatory frequency, and oxygen concentration. This tactic was eventually abandoned after further research stressed the harmful effects of large ...
Inborn errors of metabolism (IEM) comprise a group of over 600 disorders, each with a specific metabolic impairment due to a genetic defect. Urea cycle disorders (UCD) are IEM that affect the nitrogen disposal system, leading to hyperammonemia and the accumulation of other toxic metabolites in tissues of affected patients. UCD arise from mutations in the genes coding any of the enzymes participating in the urea cycle, either directly or as regulators of this pathway, causing severe respiratory alkalosis. Considering that the exact mechanisms underlying the damage found in UCD, the purpose of this minireview is to obtain data and search for links between UCD and oxidative stress, a phenomenon common to several IEM ...

Volume depletion and potassium depletion may coexist in some disorders (eg vomiting). Severe potassium depletion alone can cause a metabolic alkalosis but this is typically only of mild to moderate degree. The mechanism seems to be related to an intracellular shift of H+ (intracellular acidosis) in exchange for K+. The alkalosis is generated predominantly due to non-renal mechanisms. Renal mechanisms are frequently involved in causing the potassium depletion (eg in syndromes of mineralocorticoid excess).. Volume depletion has long been implicated in maintenance of an alkalosis. The idea is that hypovolaemia is associated with increased fluid and sodium reabsorption in the proximal tubule and bicarbonate is reabsorbed in preference to chloride; the alkalosis thus being maintained. The role of volume depletion has probably been over-emphasised: the co-existing chloride depletion is the most important factor responsible for persistence of the alkalosis. Correction of the volume deficit without ...

Cerebral blood flow was measured with the 133Xenon clearance method during short-lasting (20 minutes) and more prolonged (90 minutes) infusions of Na2CO3 solutions in anesthetized cats under controlled ventilation. The infusion protocol was regulated so as to produce a given increase in the plasma [HCO3-] in the first 15 minutes, followed by a constant high plasma level for the rest of the infusion period. A high Paco3 level was induced before and at the end of the infusion, when prolonged infusions were made. The results indicate that, in acute experiments (20 minutes), an increase in plasma [HCO3-] of 14 mEq/l does not influence CBF. During more prolonged infusions (90 minutes), an increase of 12 mEq/l produces a reduction of CBF and an increase in the CSF [HCO3-]. These changes are more pronounced when the increase in plasma [HCO3-] is more marked (18 mEq/l).. ...

We measured cerebral intracellular pH using in vivo phosphorus-31 nuclear magnetic resonance spectroscopy during 1 week after forebrain ischemia or sham operation in eight and seven rats, respectively. Mean maximum pH was significantly higher (p less than 0.003) in the ischemic group than in the sham-operated group (7.34 +/- 0.03 and 7.19 +/- 0.02, respectively). The difference between mean maximum pH and baseline pH (7.08 +/- 0.01 in each group) was significantly greater (p less than 0.02) in the ischemic group than in the sham-operated group. In the ischemic group, alkalosis occurred primarily after 48-72 hours of recirculation. We speculate that brain tissue alkalosis occurring chronically after ischemia is associated with delayed ischemic neuronal death. ...
