Arterial blood gas tensions during upper gastrointestinal endoscopy. (1/1825)

Arterial blood gas tensions were measured before and during upper gastrointestinal endoscopy, with (group I) and without (group 2) sedation with intravenous diazepam. There was a highly significant fall in the PaO2, which occurred in both groups and was therefore not attributable to diazepam. Measurement of FEV, and FVC before endoscopy had no predictive value for those patients whose PaO2 fell the most.  (+info)

Energy cost of propulsion in standard and ultralight wheelchairs in people with spinal cord injuries. (2/1825)

BACKGROUND AND PURPOSE: Wheelchair- and subject-related factors influence the efficiency of wheelchair propulsion. The purpose of this study was to compare wheelchair propulsion in ultralight and standard wheelchairs in people with different levels of spinal cord injury. SUBJECTS: Seventy-four subjects (mean age=26.2 years, SD=7.14, range=17-50) with spinal cord injury resulting in motor loss (30 with tetraplegia and 44 with paraplegia) were studied. METHOD: Each subject propelled standard and ultralight wheelchairs around an outdoor track at self-selected speeds, while data were collected at 4 predetermined intervals. Speed, distance traveled, and oxygen cost (VO2 mL/kg/m) were compared by wheelchair, group, and over time, using a Bonferroni correction. RESULTS: In the ultralight wheelchair, speed and distance traveled were greater for both subjects with paraplegia and subjects with tetraplegia, whereas VO2 was less only for subjects with paraplegia. Subjects with paraplegia propelled faster and farther than did subjects with tetraplegia. CONCLUSION AND DISCUSSION: The ultralight wheelchair improved the efficiency of propulsion in the tested subjects. Subjects with tetraplegia, especially at the C6 level, are limited in their ability to propel a wheelchair.  (+info)

Pulmonary capillary perfusion: intra-alveolar fractal patterns and interalveolar independence. (3/1825)

Pulmonary capillary perfusion was analyzed from videomicroscopic recordings to determine flow switching characteristics among capillary segments in isolated, blood-perfused canine lungs. Within each alveolus, the rapid switching pattern was repetitive and was, therefore, nonrandom (fractal dimensions near 1.0). This self-similarity over time was unexpected in a network widely considered to be passive. Among adjacent alveoli, the relationship among the switching patterns was even more surprising, for there was virtually no relationship between the perfusion patterns (coefficients of determination approaching zero). These findings demonstrated that the perfusion patterns in individual alveolar walls were independent of their next-door neighbors. The lack of dependence among neighboring networks suggests an interesting characteristic: the failure of one alveolar-capillary bed would leave its neighbors relatively unaffected, a feature of a robust design.  (+info)

Lactate kinetics at rest and during exercise in lambs with aortopulmonary shunts. (4/1825)

In a previous study [G. C. M. Beaufort-Krol, J. Takens, M. C. Molenkamp, G. B. Smid, J. J. Meuzelaar, W. G. Zijlstra, and J. R. G. Kuipers. Am. J. Physiol. 275 (Heart Circ. Physiol. 44): H1503-H1512, 1998], a lower systemic O2 supply was found in lambs with aortopulmonary left-to-right shunts. To determine whether the lower systemic O2 supply results in increased anaerobic metabolism, we used [1-13C]lactate to investigate lactate kinetics in eight 7-wk-old lambs with shunts and eight control lambs, at rest and during moderate exercise [treadmill; 50% of peak O2 consumption (VO2)]. The mean left-to-right shunt fraction in the shunt lambs was 55 +/- 3% of pulmonary blood flow. Arterial lactate concentrations and the rate of appearance (Ra) and disappearance (Rd) of lactate were similar in shunt and control lambs, both at rest (lactate: 1, 201 +/- 76 vs. 1,214 +/- 151 micromol/l; Ra = Rd: 12.97 +/- 1.71 vs. 12.55 +/- 1.25 micromol. min-1. kg-1) and during a similar relative workload. We found a positive correlation between Ra and systemic blood flow, O2 supply, and VO2 in both groups of lambs. In conclusion, shunt lambs have similar lactate kinetics as do control lambs, both at rest and during moderate exercise at a similar fraction of their peak VO2, despite a lower systemic O2 supply.  (+info)

Evidence of O2 supply-dependent VO2 max in the exercise-trained human quadriceps. (5/1825)

Maximal O2 delivery and O2 uptake (VO2) per 100 g of active muscle mass are far greater during knee extensor (KE) than during cycle exercise: 73 and 60 ml. min-1. 100 g-1 (2.4 kg of muscle) (R. S. Richardson, D. R. Knight, D. C. Poole, S. S. Kurdak, M. C. Hogan, B. Grassi, and P. D. Wagner. Am. J. Physiol. 268 (Heart Circ. Physiol. 37): H1453-H1461, 1995) and 28 and 25 ml. min-1. 100 g-1 (7.5 kg of muscle) (D. R. Knight, W. Schaffartzik, H. J. Guy, R. Predilleto, M. C. Hogan, and P. D. Wagner. J. Appl. Physiol. 75: 2586-2593, 1993), respectively. Although this is evidence of muscle O2 supply dependence in itself, it raises the following question: With such high O2 delivery in KE, are the quadriceps still O2 supply dependent at maximal exercise? To answer this question, seven trained subjects performed maximum KE exercise in hypoxia [0.12 inspired O2 fraction (FIO2)], normoxia (0.21 FIO2), and hyperoxia (1.0 FIO2) in a balanced order. The protocol (after warm-up) was a square wave to a previously determined maximum work rate followed by incremental stages to ensure that a true maximum was achieved under each condition. Direct measures of arterial and venous blood O2 concentration in combination with a thermodilution blood flow technique allowed the determination of O2 delivery and muscle VO2. Maximal O2 delivery increased with inspired O2: 1.3 +/- 0.1, 1.6 +/- 0.2, and 1.9 +/- 0.2 l/min at 0.12, 0.21, and 1.0 FIO2, respectively (P < 0.05). Maximal work rate was affected by variations in inspired O2 (-25 and +14% at 0.12 and 1.0 FIO2, respectively, compared with normoxia, P < 0.05) as was maximal VO2 (VO2 max): 1.04 +/- 0.13, 1. 24 +/- 0.16, and 1.45 +/- 0.19 l/min at 0.12, 0.21, and 1.0 FIO2, respectively (P < 0.05). Calculated mean capillary PO2 also varied with FIO2 (28.3 +/- 1.0, 34.8 +/- 2.0, and 40.7 +/- 1.9 Torr at 0.12, 0.21, and 1.0 FIO2, respectively, P < 0.05) and was proportionally related to changes in VO2 max, supporting our previous finding that a decrease in O2 supply will proportionately decrease muscle VO2 max. As even in the isolated quadriceps (where normoxic O2 delivery is the highest recorded in humans) an increase in O2 supply by hyperoxia allows the achievement of a greater VO2 max, we conclude that, in normoxic conditions of isolated KE exercise, KE VO2 max in trained subjects is not limited by mitochondrial metabolic rate but, rather, by O2 supply.  (+info)

Analysis of blood flow in the long posterior ciliary artery of the cat. (6/1825)

PURPOSE: Experiments were undertaken to use a new technique for direct on-line measurement of blood flow in the long posterior ciliary artery (LPCA) in cats and to evaluate possible physiological mechanisms controlling blood flow in the vascular beds perfused by this artery. METHODS: Blood flow in the temporal LPCA was measured on a continuous basis using ultrasonic flowmetry in anesthetized cats. Effects of acute sectioning of the sympathetic nerve and changes in LPCA and cerebral blood flows in response to altered levels of inspired CO2 and O2 were tested in some animals. In others, the presence of vascular autoregulatory mechanisms in response to stepwise elevations of intraocular pressure was studied. RESULTS: Blood flow in the temporal LPCA averaged 0.58+/-0.03 ml/min in 45 cats anesthetized with pentobarbital. Basal LPCA blood flow was not altered by acute sectioning of the sympathetic nerve or by changes in low levels of inspired CO2 and O2, although 10% CO2 caused a modest increase. Stepwise elevations of intraocular pressure resulted in comparable stepwise decreases of LPCA blood flow, with perfusion pressure declining in a linear manner throughout the perfusion-pressure range. CONCLUSIONS: Ultrasonic flowmetry seems to be a useful tool for continuous on-line measurement of LPCA blood flow in the cat eye. Blood flow to vascular beds perfused by this artery does not seem to be under sympathetic neural control and is refractory to modest alterations of blood gas levels of CO2 and O2. Blood vessels perfused by the LPCA show no clear autoregulatory mechanisms.  (+info)

Metabolic acidosis-induced retinopathy in the neonatal rat. (7/1825)

PURPOSE: Carbon dioxide (CO2)-induced retinopathy (CDIR) in the neonatal rat, analogous to human retinopathy of prematurity (ROP), was previously described by our group. In this model, it is possible that CO2-associated acidosis provides a biochemical mechanism for CDIR. Therefore, the effect of pure metabolic acidosis on the developing retinal vasculature of the neonatal rat was investigated. METHODS: A preliminary study of arterial blood pH was performed to confirm acidosis in our model. In neonatal rats with preplaced left carotid artery catheters, acute blood gas samples were taken 1 to 24 hours after gavage with either NH4Cl 1 millimole/100 g body weight or saline. In the subsequent formal retinopathy study, 150 newborn Sprague-Dawley rats were raised in litters of 25 and randomly assigned to be gavaged twice daily with either NH4Cl 1 millimole/100 g body weight (n = 75) or saline (n = 75) from day 2 to day 7. After 5 days of recovery, rats were killed, and retinal vasculature was assessed using fluorescein perfusion and ADPase staining techniques. RESULTS: In the preliminary pH study, the minimum pH after NH4Cl gavage was 7.10+/-0.10 at 3 hours (versus 7.37+/-0.03 in controls, mean +/- SD, P < 0.01). In the formal retinopathy study, preretinal neovascularization occurred in 36% of acidotic rats versus 5% of controls (P < 0.001). Acidotic rats showed growth retardation (final weight 16.5+/-3.0 g versus 20.2+/-2.6 g, P < 0.001). The ratio of vascularized to total retinal area was smaller in acidotic rats (94%+/-4% versus 96%+/-2%, P < 0.001). CONCLUSIONS: Metabolic acidosis alone induces neovascularization similar to ROP in the neonatal rat. This suggests a possible biochemical mechanism by which high levels of CO2 induce neovascularization and supports the suggestion that acidosis may be an independent risk factor for ROP.  (+info)

Continuous arterial P(O2) and P(CO2) measurements in swine during nitrous oxide and xenon elimination: prevention of diffusion hypoxia. (8/1825)

BACKGROUND: During nitrous oxide (N2O) elimination, arterial oxygen tension (PaO2) decreases because of the phenomenon commonly called diffusive hypoxia. The authors questioned whether similar effects occur during xenon elimination. METHODS: Nineteen anesthetized and paralyzed pigs were mechanically ventilated randomly for 30 min using inspiratory gas mixtures of 30% oxygen and either 70% N2O or xenon. The inspiratory gas was replaced by a mixture of 70% nitrogen and 30% oxygen. PaO2 and carbon dioxide tensions were recorded continuously using an indwelling arterial sensor. RESULTS: The PaO2 decreased from 119+/-10 mm Hg to 102+/-12 mm Hg (mean+/-SD) during N2O washout (P<0.01) and from 116+/-9 mm Hg to 110+/-8 mm Hg during xenon elimination (P<0.01), with a significant difference (P<0.01) between baseline and minimum PaO2 values (deltaPaO2, 17+/-6 mm Hg during N2O washout and 6+/-3 mm Hg during xenon washout). The PaCO2 value also decreased (from 39.3+/-6.3 mm Hg to 37.6+/-5.8 mm Hg) during N2O washout (P<0.01) and during xenon elimination (from 35.4+/-1.6 mm Hg to 34.9+/-1.6 mm Hg; P< 0.01). The deltaPaCO2 was 1.7+/-0.9 mm Hg in the N2O group and 0.5+/-0.3 mm Hg in the xenon group (P<0.01). CONCLUSION: Diffusive hypoxia is unlikely to occur during recovery from xenon anesthesia, probably because of the low blood solubility of this gas.  (+info)

N2 - This study assessed the degree to which correcting blood gas measurements to rectal temperature (T(re)) rather than to the temperatures at which gas exchange occurs [pulmonary arterial (T(pa)) or intramuscular (T(m))] introduces errors into blood gas analysis of exercising mammals. Horses and steers weighing 450 kg were run on a treadmill at speeds up to those eliciting maximal rates of O2 consumption (V̇O(2max)), and temperatures were measured in various body compartments. In both species T(pa) rose faster than T(re) during the run, the degree of dissociation being a function of exercise intensity and duration. T(m) was measured only in horses, and it rose faster than T(pa) during the run and decreased more slowly postrun. Correcting blood gas values ...
Glucose control to prevent both hyperglycemia and hypoglycemia is important in an intensive care unit [1]. Recent meta-analysis, including results of the NICE-SUGAR study [2], showed that intensive insulin therapy (target blood-glucose control, 80 to 110 mg/dl) was not beneficial and increased the risk of severe hypoglycemia in critically ill patients [3-5]. Thus, it is currently recommended that insulin should be used when the glucose concentration exceeds 180 mg/dl, and target glucose concentration should generally be between 144 and 180 mg/dl [6, 7]. Even though a more-modest target for blood-glucose concentration is now accepted, the importance of glucose monitoring and its accuracy has become clearer. Because the physiological activity of glucose is dependent on its plasma concentration, central laboratory blood-glucose measurement using plasma (Glu-lab) is recommended [8, 9]. However, arterial blood gas analyzers (ABGs) and/or glucose meters, not Glu-lab, are commonly used to measure ...

The present study was designed to examine the anatomical parameters of the cardiopulmonary system, the function of venous blood gas parameters and the development of ascites incidence in two genetic line chickens. Three hundred forty day-old chickens from two pure broiler breeder lines, which were different in their growth rate and susceptibility to ascites syndrome were obtained. The relative heart and lung weights, the volumes of the heart, lung and thorax cavity, the incidence of ascites, and the venous blood gas parameters in these two genetic line chickens were followed. In the present study, the incidence of ascites and right ventricular hypertrophy was markedly higher in the fast-growing broiler chickens compared to the slow-growing chickens, as two genetic line chickens exhibited significant differences in their growth performance traits. The volumes of the thorax cavity, before and after removing the heart and lung tissues, were lower in fast-growing broiler chickens compared to the slow

The perinatal period (labor, parturition, and the days following) is one of fundamental change in the cardiorespiratory status of the baby. Nutritional, excretory, and respiratory systems must rapidly assume new responsibilities as the organism changes from a dependent to a free-living individual. Respiratory gas exchange, formerly a placental function, must be established by the lungs within minutes after birth. The cardiovascular system undergoes changes just as dramatic, with conversion from two circulations in parallel to two circulations now in series. Therefore, frequent and serious difficulties in cardiorespiratory adaptation in the perinatal and neonatal periods are not surprising.. Blood gas measurements and complementary, noninvasive monitoring techniques provide the clinician with information essential to patient assessment, therapeutic decision making, and prognostication. Blood gas measurements are as important for ill newborn infants as for other critically ill patients, but unique ...

An arterialblood gas analysis which is conducted in critical care areas contributes to the assessment of a patients ventilatory status and acid -base balance. The purpose of this research was to determine the relationship of time delays and temperature on the result of a blood gas analysis. The objective was to either accept or refute the null hypothesis, that there is no relationship between temperature and time delays and an arterial blood gas result Fifteen subjects were randomly selected. The researcher drew three samples of arterial blood from each subject. Ethical principles were observed. An inferential non-parametric statistic was used. The chi-squared test was used to test the hypothesis and the Friedman and the Wilcoxon signed ranks test were used to test the differences between the means. The results revealed that there was a relationship between time delays, temperature and the arterial blood gas result. The null hypothesis was rejected ...

In view of the plethora of published material available on this area, the author justifies yet another contribution by alluding to the excessive complexities and uneven literary quality of existing texts. Unfortunately, Dr. Tullers approach is excessively simplified, in this reviewers opinion.. He suggests that plasma [HCO3-] is never directly altered by changes in ventilation because the bicarbonate ion is not volatile. If this were indeed correct, then the PCO2 would inform us about alveolar ventilation, whereas the [HCO3-] would be a purely metabolic index. Unfortunately, in the presence of protein buffers in the blood, [HCO3-] is acutely altered by ...

Solves Lactate Pre-Analytical issues ...
These advances went hand-in-hand with the establishment of pioneering national and international organ transplant programmes for heart, kidney and liver transplants in Cape Town. This necessitated improved anaesthetic skills to provide peri-operative care and anaesthesia for critically ill transplant recipients (adult and paediatric). The liver transplantation programme, regarded by many as inappropriate for the SA environment, proved to be extremely successful in both adult and paediatric patients. Further positive benefits included the acquisition of point-of-care equipment in theatre, such as thrombelastography and blood gas analysers.. In January 2008 one of the authors (PG) attended the World Health Organization (WHO) meeting to finalise the Surgical Safety Check List (SSCL). The check-list was implemented at GSH and across the Western Cape (WC) province, and was recently adopted as a national core standard for hospitals by the national Department of Health (DoH).. In 2006 the WC DoH ...

The importance of SaO2 in the assessment of respiratory distress in bronchial asthma has been reported. Objectives: To evaluate the correlation between blood gas analysis and chest X-ray lung opacities in young children presenting with acute respiratory symptoms. Methods: Eighty patients (43 males and 37 females aged 0.5-24 months; mean B SD 9.1 B 7.2 months), either with acute wheezing respiratory symptoms and/or with crackles were enrolled in our study. In all children, blood gas analysis and chest X-rays were performed within 12 h following admission to the emergency department. Results: In 55 children (68.75%) chest X-rays demonstrated lung opacities. Subjects with normal X-rays had paO2 and SaO2 higher than subjects with lung opacities (p ! 0.0001 and p = 0.0001, respectively). Children with lung opacities almost always presented paO2 !80 mm Hg. Sensitivity and specificity for the presence of lung opacities of paO2 !80 mm Hg were 81 and 90%, respectively, while sensitivity and specificity ...

Cyanosis is the bluish or purplish discolouration of the skin or mucous membranes due to the tissues near the skin surface having low oxygen saturation. Based on Lundsgaard and Van Slykes work,[1] it is classically described as occurring if 5.0 g/dL of deoxyhemoglobin or greater is present.[2] This was based on an estimate of capillary saturation based on a mean of arterial versus peripheral venous blood gas measurements.[3] Since estimation of hypoxia is usually now based either on arterial blood gas measurement or pulse oximetry, this is probably an overestimate, with evidence that levels of 2.0 g/dL of deoxyhemoglobin may reliably produce cyanosis.[4] Since, however, the presence of cyanosis is dependent upon there being an absolute quantity of deoxyhemoglobin, the bluish color is more readily apparent in those with high hemoglobin counts than it is with those with anemia. Also, the bluer the color, the more difficult it is to detect on deeply pigmented skin. When signs of cyanosis first ...

Aftercare. Maintain pressure over the arterial puncture site for several minutes. This action can be delegated to an assistant, while the person who performed the procedure disposes of the sharps, labels the specimen, and organises for it to be analysed.. Check the patient several minutes after the procedure to make sure that the perfusion of the extremity is adequate and the arterial puncture site is not haemorrhaging or forming a haematoma.. Send the sample for analysis immediately, labelling and documenting the inspired oxygen concentration clearly.. Normal values for arterial blood vary slightly in each laboratory and machine, and these values should be cross-referenced when interpreting the results of arterial blood gas analysis. Some blood gas analysers also need the patients temperature.. An unexpected or very abnormal result may indicate serious pathology or indicate that a venous sample was taken. ...
There is much controversy about the optimal bloodgas management of hypothermic patients, whether the hypothermia is caused by accidents or induced before operations. The surgeons and anestesiologists have acquired more clinical experience the last years when operating patients in hypothermia. The comparative physiology has given increased information about the blood gas strategy of heterothermic endotherms and poikilothermic ectotherms during lowering of their core temperature. There are two types of strategies which have been used in clinical medicine the last years in the blood gas management of patients in hypothermia: pH-stat method and alpha-stat method. In the pH-stat method, the arterial carbon dioxide tension (pCO2(a)) is maintained at 5.3 kPa (40 mmHg) and the pH is maintained at 7.40 when measured at the actual temperature. It is then necessary to add CO2 to the inspired gas. In the alpha-method, the arterial carbon dioxide tension and the pH are maintained at 5.3 kPa and 7.40 when ...

In the blood gas analyser, the haemoglobin concentration is measured directly, using visible absorption spectroscopy. The local unit features a 128-wavelength spectrophotometer with a measuring range of 478-672 nm. Absorption spectroscopy is based on Lambert-Beers law, which relates the properties of transmitted light to the properties of the substance through which it is transmitted. The absorbance, in this scenario, is defined as the logarithm of the ratio of the light intensity before and after transmission through the compound. Each haemoglobin species has a different extinction coefficient (ε) and these are known from empiric measurements.
TY - JOUR. T1 - Serum phosphate is an important determinant of corrected serum calcium in end-stage kidney disease. AU - Ferrari, Paolo. AU - Singer, R.. AU - Agarwal, A.. AU - Hurn, A.. AU - Townsend, M.A.. AU - Chubb, P.. PY - 2009. Y1 - 2009. N2 - Background: Approximately 12% of bound blood calcium is linked to various anions including phosphate. In patients with end-stage kidney disease (ESKD), serum phosphate is highly variable. We propose that establishing a formula to calculate albumin- and phosphate-corrected total calcium would be more appropriate to estimate free calcium in ESKD patients.Methods: In 82 haemodialysis patients, serum ionized calcium (Caion) and pH were measured by blood gas analyser with ion-selective electrodes at the point-of-care, while bicarbonate, phosphate, albumin, magnesium and total calcium (Catot) were measured at the central laboratory. Linear regression analysis of measured variables was used to best fit adjusted calcium versus Caion.Results: The most ...
analysis. It is a common procedure in the hospital to allow assessment of pulmonary gas exchange. Compared with vein puncture, arterial puncture is more difficult, requires deeper needle insertion and is more painful for the patient. Cryoanalgesia would offer a noninvasive, nonpharmacologic, inexpensive and readily available tool to reduce pain associated with arterial puncture. This study sought to determine whether cryoanalgesia in the form of ice application could be an effective analgesic when applied before arterial puncture. Methodology:This was a prospective study with a convenience sample of intensive care unit patients on oxygen therapy with a physician order for an ABG test. The intervention group had a plastic bag of ice applied to their wrists for 3 min before drawing an ABG sample from the radial artery. The control group had an ABG sample drawn from the radial artery without the application of ice. Pain from the arterial puncture was measured with a pain rating scale. Results: ...

Expiratory gas sampling is commonly used as a method of continuous carbon dioxide monitoring. This is however not always easily achieved in non-intubated patients particularly those using a nasal mask. Recently, a number of studies on the usefulness of percutaneous CO2 monitoring in adult patients (non-intubated, under sedation) have been published. This is also a method which has been traditionally used in intubated neonates whose expiratory gas sampling is difficult. However, few studies have been performed on this method applied in paediatric patients. We compared percutaneous CO2 values (PtcCO2) with both arterial and end-tidal CO2 (PaCO2, EtCO2) values in paediatric patients undergoing surgical procedures to verify its reliability ...
ASL perfusion MR imaging was first described over a decade ago12,13 and has been an active area of research.14,15 One advantage of ASL over conventional bolus tracking for perfusion measurement is that it provides absolute CBF information. Quantification of CBF facilitates the identification of cases with symmetric global perfusion abnormalities (Fig 2).. Causes of global cerebral hyperperfusion include etiologies that result in global vasodilation or loss of cerebral vascular autoregulation. Carbon dioxide is a potent vasodilator, and hypercapnia can cause transient vasodilation when cerebral perfusion autoregulation pathways are intact.16-19 This property has been exploited with tests, such as the hypercapnia challenge, to evaluate the cerebral vascular reserve.17 All of the patients in our series had normal arterial blood gas measurements except for case 6. Case 6 is a case of favorable outcome while showing global hyperperfusion. Previous studies have shown up to a 200% increase in CBF as ...

OBJECTIVE: Cognitive dysfunction and postoperative hypoxia are common sequelae of coronary artery bypass grafting, but there has been no study to determine whether there is any relationship between them. METHODS: Arterial blood gas measurements were performed before surgical intervention and on the second and fifth postoperative day, and neuropsychological assessments were performed before surgical intervention and 5 days and 3 months postoperatively by using a battery of 10 psychometric tests in 175 patients undergoing coronary artery bypass grafting. An estimate of overall performance on the battery at each assessment point was provided by a simple aggregate cognitive index score calculated from the mean z scores of 4 normally distributed test variables. Multiple regression analysis was performed by using the cognitive index score at day 5 as the dependent variable, with age, sex, duration of the operation, presence or absence of cardiopulmonary bypass, preoperative cognitive index score, and arterial

A multi-component Fourier Transform InfraRed (FTIR) gas analyzer with a low spectral resolution (8cm-1) is described in this paper. The hardware of this analyzer is consisting of a rugged Fourier Transform Spectrometer (FTS), an uncooled pyroelectric Deuterated L-Alanine TriGlycine Sulfate (DLATGS) detector, a glass body long-path gas cell and relevant sampling devices. The transplantable software and algorithms include the building of spectral library from the free sources such as EPA, NIST, HITRAN etc, identification of spectrum components and a modified classical least square regression with automatic baseline compensation. In order to validate this system, we implemented a continuous on-line experiment using the 55 μmol·mol-1 methane and 28 μmol·mol-1 nitrous oxide standard mixtures. The experimental results show this low resolution analyzer has accuracy and robust analysis abilities. The description in this paper is helpful to facilitate the development of a FTIR multi-component gas ...
While the findings of our investigation are promising, we acknowledge several limitations. Our study was an observational, unblinded prospective trial, and although poor clinical outcomes and major adverse events strongly correlated with ScvO2less than 40% and 50%, a prospective trial to evaluate the utility of continuous ScvO2as a target parameter of goal-directed therapy to improve clinical outcomes is warranted. Technical limitations of the ScvO2catheter were minimal from our experience and included wall artifacts caused by impingement of the catheter tip on a vessel wall that led to an unreliable signal, as detected by a signal quality index value of 4. In all cases, repositioning of the catheter resulted in restoration of an appropriate signal. Although the study was not blinded, the practice in our ICU before the study and the study protocol required therapeutic interventions to be made primarily using confirmed venous desaturations from intermittent venous blood gas samples and/or other ...
Arterial blood gas analysis with co-oximetry was performed on samples obtained from the dorsal pedal artery. Median SpO2 was 91.5% (range 80-97%) and median PaO2 was 70.1 mmHg (range 44.5-103.8 mmHg). Hypoventilation was uncommon and venous admixture was the predominant cause of hypoxemia in this population. Median SF was 435.7 (range 381.0-461.9) and median PF was 334.0 (range 211.9-494.3). Nine dogs (23.6%) had PF ,300; no dogs had PF below 200. SF and PF were correlated (ρ = 0.618, P , 0.01 ...
ABG interpretation can be perplexing to a provider, although an imbalance can lead to severe complications from the lack of homeostasis of the body and thus become a life-threatening event. There are many methods of ABG analysis, but the ultimate goal is complete comprehension to allow easier interpretation and ultimately make an impact on your patients outcome. A 6-step structured approach is reviewed during this presentation, which will allow a different approach to analyze an ABG. Each component of an ABG will be reviewed including what each component represents, and various compensatory mechanisms. To practice and confirm the providers comprehension of the steps of ABG interpretation, and the physiological principles behind blood gas analysis, actual patient case studies will be utilized and reviewed ...
