The results from the meta-analysis are in accord with recent literature questioning the decrease in mortality in ARDS in the past decade despite the implementation of new ventilatory strategies.6-8 In the ARDSNet trial,9 a significant reduction in mortality was observed when a "protective strategy," based on a low tidal volume (6 ml/kg), was used. But we may speculate that patients were actually being protected from an "aggressive strategy" (tidal volume 12 ml/kg in the control arm). It is likely that the application of a high PEEP in the initial phase of severe ARDS, with an expected important lung edema and inflammation, is justified.10 Even accepting this approach, it remains unanswered for how long the PEEP should be "high." The lack of clear benefits in unselected patients is probably related to the absence of objective tests that help in the individual titration of the ventilatory parameters. Several techniques have been proposed, such as the plotting of pressure-volume curves,11 the ...
A bi-level pressure support system and method of treating disordered breathing that optimizes the pressure delivered to the patient during inspiration and expiration to treat the disordered breathing while minimizing the delivered pressure for patient comfort. The pressure generating system generates a flow of breathing gas at an inspiratory positive airway pressure (IPAP) during inspiration and at an expiratory positive airway pressure (EPAP) during expirations. A controller monitor at least one of the following conditions: (1) snoring, (2) apneas, (3) hypopneas, or (4) a big leak in the pressure support system and adjusts the IPAP and the EPAP based on the occurrence of any one of these conditions.

Noninvasive positive pressure ventilation (NIPPV) has been commonly applied in several clinical and postoperative conditions, especially after coronary artery bypass grafting (CABG) surgery and it can cause breathing pattern (BP) alterations and mechanical effects on cardiovascular system, with cardiac autonomic adjustments. However, it is not well established in the literature how these alterations occur in patients submitted to the CABG and if they can be related to the application of different positive airway pressure levels. In this context, we considered the development of two studies that could contribute with new information about these topics. The first study is entitled Acute application of bilevel positive airway pressure influence cardiac autonomic nervous system and its objective was to evaluate the changes in heart rate variability (HRV) during bilevel positive airway pressure (Bilevel) application in healthy young men. Twenty men underwent a 10-min register of R-R intervals (R-Ri) ...

TY - JOUR. T1 - Hemodynamic benefit of positive end-expiratory pressure during acute descending aortic occlusion. AU - Johnston, William E.. AU - Conroy, Brendan P.. AU - Miller, Gregory S.. AU - Lin, Cheng Y.. AU - Deyo, Donald J.. PY - 2002/10/1. Y1 - 2002/10/1. N2 - Background: Acute aortic occlusion in vascular surgery patients abruptly increases arterial resistance and blood pressure, which, in turn, makes subsequent volume expansion during cross-clamp application difficult. The use of vasodilatory drugs or volatile anesthetic agents to attenuate this response may have persistent detrimental effects after clamp removal. Another potential therapy that produces rapid effects on myocardial loading conditions is positive end-expiratory pressure (PEEP). In a porcine model of acute aortic clamping, the hemodynamic consequences of 15 cm H2O PEEP with and without plasma volume expansion were studied. Methods: Forty anesthetized pigs underwent 30-min occlusion of the abdominal aorta 1 cm above the ...
Current evidence in mechanical ventilation supports a protective lung strategy that is, smaller tidal volumes and prevention of loss of positive end expiratory pressure (PEEP). There is concern that manual hyperinflation (MHI) may conflict with this strategy and cause volutrauma and atelectrauma potentially leading to biotrauma.. This single-blinded randomized study aims to compare two methods of manual hyperinflation (protective - moderate tidal volumes with positive end expiratory pressure) and non-protective (large tidal volume and no positive end expiratory pressure) in ventilated acute trauma patients, to investigate the effect on inflammatory markers, lung compliance, oxygenation and sputum volume. ...
In the acute setting non-invasive positive pressure ventilation (NPPV) is aimed at avoiding intubation and intubation-related complications. In some conditions such as acute exacerbation of chronic obstructive pulmonary disease the avoidance of intubation gained by NPPV has been shown to substantially improve intensive care unit (ICU) survival. However, NPPV is typically performed in conscious patients and might eventually fail as a reason of intolerance or inefficiency. In this scenario intubation occurs possibly too late, which negatively impacts on prognosis. Therefore, the issue of NPPV failure is acknowledged to be of major importance. In general, two global reasons can be responsible for NPPV failure, firstly, predefined conditions independent from staff handling, and secondly, common treatment mistakes. Predefined conditions are unchangeable and primarily refer to specific underlying conditions (e.g. hypoxemic versus hypercapnic respiratory failure), disease severity, and complications ...

Literature Review:. Airway management is a cornerstone of both basic and advanced life support. Paramedics and other EMS providers frequently encounter patients who can no longer protect their own airways (traumatic brain injury, major polytrauma, intoxication and overdose) or who are experiencing impending respiratory failure (exacerbations of congestive heart failure and obstructive lung disease). In-hospital management for these patients typically includes endotracheal intubation (ETI), which provides definitive control of the airway, reduces aspiration risk, and allows for mechanical ventilatory support. Do any of these patients benefit from pre-hospital ETI? Should EMS providers intubate in the field, or should they use airway adjuncts such as bag-valve mask ventilation, supraglottic airway devices, or non-invasive positive pressure ventilation to temporize their patients during rapid transport to the hospital?. As one might expect, the data on this issue are mixed and generally poor in ...
The foramen ovale is a congenital opening between the two cardiac atria that usually closes shortly after birth but may remain patent. Thus, a patent foramen ovale (PFO) is found at autopsy in 20 to 34% of the general population [1]. The PFO represents a channel through which unidirectional blood flow from the right venous blood to the left oxygenated arterial system may occur. The passage of blood from the venous blood into the left arterial blood without lung oxygenation is named right-to-left shunt. It may be associated with hypoxemia, defined in terms of reduced oxygen pressure in the systemic arterial blood (PaO2), as detected by an arterial blood gas (ABG) measurement at rest.. Right atrial pressures are elevated in patients with pulmonary hypertension (PH), which may be primary or secondary to another condition such as chronic obstructive pulmonary disease (COPD) or obstructive sleep apnea syndrome (OSAS) [2], and enhance the chance of a right-to-left intracardiac shunt through the ...
Measurements were obtained first at zero end-expiratory pressure (ZEEP). PEEP was then applied in increments of 2 cm H20. At each PEEP level, measurements were done after patients were judged to have reached a steady state by stability of the RIP sum signal and Pao signal (usually within 1 min). End-inspiratory occlusions were obtained by pressing the inspiratory hold button of the ventilator for 5 to 6 s. During this period, the contribution of reduction in pressure due to volume loss by continuing gas exchange should be negligible. On reestablishing a steady state (usually within a few breaths), end-expiratory occlusions were done by pressing the end-expiratory hold button of the ventilator for 5 to 6 s.. All patients were studied up to a PEEP of 10 cm H20. In seven patients, higher levels of PEEP were used (up to 12 to 18 cm H20). The above measurements were then performed while PEEP was reduced stepwise to zero in decrements of 2 cm HaO. The whole procedure was repeated three times. ...

Background: Positive pressure ventilation in premature infants can improve oxygenation but may diminish cerebral blood flow and cardiac output. Low superior vena cava (SVC) flow increases risk of intraventricular haemorrhage, and higher mean airway pressure is associated with low SVC flow. Whether this is a direct effect of positive pressure ventilation or a reflection of severity of lung disease is not known. This study aimed to determine if positive end expiratory pressure (PEEP) in ventilated newborns could be increased without clinically relevant cardiorespiratory changes.. Method: Ventilated newborns were studied before and 10 min after increasing PEEP (5 cm H2O to 8 cmH2O) and again when PEEP returned to baseline. Echocardiographic and respiratory function measurements were collected during the intervention.. Results: In 50 infants, increased PEEP was associated with a non-significant difference in mean SVC flow of −5 ml/kg/min (95% CI −12 to 3 ml/kg/min) but a significant reduction in ...

Positive end-expiratory pressure (PEEP) has been demonstrated to improve systemic arterial oxygenation in respiratory distress secondary to interstitially edematous lung. Clinical improvements, however, may be limited by the adverse circulatory effects of PEEP impairing venous return and reducing cardiac output. In an effort to eliminate this variable experimentally, the effects of graded levels of PEEP in the isolated canine lung made edematous by venous constriction were studied. These observations suggested that the increased mean inflation pressures of PEEP do not facilitate mobilization of interstitial fluid nor improve lung mechanics and that the observed improvement in gas exchange probably relateds to inflation of previously collapsed alveoli. In clinical use, however, PEEP is applied at one level for a prolonged period of time. Therefore, to delineate the prolonged effects of static PEEP, isolated canine lungs made edematous by venous constriction were treated with various levels of PEEP
PURPOSE: ALI and ARDS are associated with lung volume derecruitment, usually counteracted by PEEP and recruitment maneuvers (RM), which should be accurately tailored to the patients needs. The aim of this study was to investigate the possibility of monitoring the amount of derecruited lung by the forced oscillation technique (FOT). METHODS: We studied six piglets (26 +/- 2.5 kg) ventilated by a mechanical ventilator connected to a FOT device that produced sinusoidal pressure forcing at 5 Hz. The percentage of non-aerated lung tissue (V (tiss)NA%) was measured by whole-body CT scans at end-expiration with zero end-expiratory pressure. Respiratory system oscillatory input reactance (X (rs)) was measured simultaneously to CT and used to derive oscillatory compliance (C (X5)), which we used as an index of recruited lung. Measurements were performed at baseline and after several interventions in the following sequence: mono-lateral reabsorption atelectasis, RM, bi-lateral derecruitment induced by ...

Lancet. 2014 Aug 9;384(9942):495-503. doi: 10.1016/S0140-6736(14)60416-5.. PROVE Network Investigators for the Clinical Trial Network of the European Society of Anaesthesiology, Hemmes SN et al,. BACKGROUND: The role of positive end-expiratory pressure in mechanical ventilation during general anaesthesia for surgery remains uncertain. Levels of pressure higher than 0 cm H2O might protect against postoperative pulmonary complications but could also cause intraoperative circulatory depression and lung injury from overdistension. We tested the hypothesis that a high level of positive end-expiratory pressure with recruitment manoeuvres protects against postoperative pulmonary complications in patients at risk of complications who are receiving mechanical ventilation with low tidal volumes during general anaesthesia for open abdominal surgery.. INTERPRETATION: A strategy with a high level of positive end-expiratory pressure and recruitment manoeuvres during open abdominal surgery does not protect ...
Nutritional and Respiratory Support. · According to natural history of the disease, nearly all Type 1 patients require nutritional and respiratory support by 12 months of age, and are not able to swallow or speak effectively.. · As of August 7, 2017, patients who were free of respiratory or feeding support on January 20, 2017, continued without the need for supportive care.. · As of August 7, 2017, six of seven (86%) patients in Cohort 2 that did not require feeding support before treatment continued without feeding support after treatment; seven of 10 (70%) patients that did not require bi-level positive airway pressure (BiPAP) support before treatment did not require BiPAP support at last assessment.. · As of August 7, 2017, eleven of 12 (92%) patients in Cohort 2 were fed orally, and six of 12 (50%) patients were exclusively fed orally.. · Further, as of August 7, 2017, eleven of 12 (92%) patients were able to speak; three more patients than previously reported on April 25, 2017 at the ...

Case Report: On 15 July 2009, we admitted a previously healthy woman to the intensive care unit in a Hong Kong hospital for novel H1N1 human swine influenza (H1N1) pneumonia with septic shock and type 1 respiratory failure. She was 48 years of age, was not obese, and was a long-term smoker. She required pressure-controlled ventilation with 100% oxygen, 18-cm H2O positive end-expiratory pressure, and inhaled nitric oxide at 20 ppm to maintain blood oxygen saturation above 90%. We started treatment with norepinephrine infusion and physiologic doses of hydrocortisone for septic shock. Test results for bacterial co-infection were negative ...
Nasal expiratory positive airway pressure (Nasal EPAP) is a treatment for obstructive sleep apnea (OSA) and snoring. Contemporary EPAP devices have two small valves that allow air to be drawn in through each nostril, but not exhaled; the valves are held in place by adhesive tabs on the outside of the nose. The mechanism by which EPAP may work is not clear; it may be that the resistance to nasal exhalation leads to a buildup in CO2 which in turn increases respiratory drive, or that resistance to exhalation generates pressure that forces the upper airway to open wider. In OSA it appears to be effective to reduce but not eliminate apnea for people with mild to moderate OSA (Apnea-hypopnea index < 30) and for people who cannot tolerate CPAP, but within those groups it is not clear why some respond and others do not, and the evidence consists of small clinical trials with follow-up no longer than one year. As of 2015 there was evidence from one small trial that it may be useful in children with OSA. ...
Post-Polio Health International, of which International Ventilator Users Network is an affiliate, announced that it has awarded a $25,000 research grant to a team from Johns Hopkins University. The researchers propose to determine whether early use of noninvasive positive pressure ventilation (NIPPV) prolongs survival in patients with amyotrophic lateral sclerosis (ALS) and to relate their findings to other neuromuscular diseases including polio and its late effects.. ALS, also known as Lou Gehrigs disease, is a progressive neurodegenerative disease that attacks nerve cells in the brain and spinal cord resulting in muscle weakness, atrophy and, eventually, death. The respiratory muscles are invariably affected, and respiratory failure is the most common cause of death in ALS patients.. NIPPV is becoming an increasingly standard treatment for patients with chronic respiratory failure, and observational studies suggest that NIPPV prolongs survival, but it is not known whether it modifies disease ...
We examined the effect of ventilation strategy on lung inflammatory mediators in the presence and absence of a preexisting inflammatory stimulus. 55 Sprague-Dawley rats were randomized to either intravenous saline or lipopolysaccharide (LPS). After 50 min of spontaneous respiration, the lungs were excised and randomized to 2 h of ventilation with one of four strategies: (a) control (C), tidal volume (Vt) = 7 cc/kg, positive end expiratory pressure (PEEP) = 3 cm H2O; (b) moderate volume, high PEEP (MVHP), Vt = 15 cc/kg; PEEP = 10 cm H2O; (c) moderate volume, zero PEEP (MVZP), Vt = 15 cc/kg, PEEP = 0; or (d) high volume, zero PEEP (HVZP), Vt = 40 cc/kg, PEEP = 0. Ventilation with zero PEEP (MVZP, HVZP) resulted in significant reductions in lung compliance. Lung lavage levels of TNFalpha, IL-1beta, IL-6, IL-10, MIP-2, and IFNgamma were measured by ELISA. Zero PEEP in combination with high volume ventilation (HVZP) had a synergistic effect on cytokine levels (e.g., 56-fold increase of TNFalpha ...
Pearl: Strongly consider using lung-protective ventilation strategies in patient with acute respiratory failure in the emergency department3. Most patients in the ED should be placed on assist-control (AC) mode, which is usually a volume cycled or (tidal) volume controlled mode of mechanical ventilation after intubation.. Ventilation (PaCO2) settings - Tidal volume (Vt) and respiratory rate (RR). For most patient, choose Vt 6-8 cc/kg (ideal body weight) In this patient with only one lung, target 6 cc/kg initially then reduce the TV if needed (we chose 260 cc). Consider the minute ventilation the patient required before intubation as well as the cause of respiratory failure when choosing a starting point.. Oxygenation (PaO2) settings - FiO2 and PEEP. Initially start your patient on 100% FiO2 and wean down to a goal of , 60%. In patients requiring single lung ventilation, its likely they will require higher FiO2s. PEEP is positive end expiratory pressure, which helps to keep alveoli open during ...

While theoretical advantages exist over standard nasal cannula and face mask oxygen, current evidence does not definitively demonstrate superiority to other methods of respiratory support. Few studies have focused on clinical outcomes beyond common respiratory parameters. Given the potential lack of consistency of positive pressure generated with current HFNC systems, NIV such as CPAP and bilevel positive airway pressure should still be considered first line therapy in moderately distressed patients in whom supplementation oxygen is insufficient and when a consistent positive pressure is indicated ...
BACKGROUND: Cardiac output (CO) is a physiological variable that should be monitored during cardiac surgery. The purpose of this study was to assess the trending ability of two CO monitors, esCCO (Nihon Kohden™, Tokyo, Japan) and Volume View (VV) (Edwards Lifesciences, Irvine, USA).. METHODS: A total of 19 patients were included in the study. Before cardiopulmonary bypass (CPB), CO was measured simultaneously using both esCCO and VV devices before and after three CO-modifying manoeuvres (passive leg raise [PLR], the end expiratory occlusion test [EEOT] and positive end expiratory pressure [PEEP] at 10 cm H2O). Five CO values for esCCO and three for VV were averaged and compared during a one-minute period of time before and after each manoeuvre.. RESULTS: A total of 114 paired readings were collected. Median CO values were 4.3 L min-1 (IQR: 3.8; 5.2) and 3.8 L min-1 (IQR: 3.5; 4.5) for esCCO and VV, respectively. The precision error was 1.4% (95% CI:1.0-1.7) for esCCO and 2.2% (95% CI: 1.8-2.7) ...

Abstract. Objective. To compare the short-term effects of a heat and moisture exchanger (HME) and a heated humidifier (HH) during non-invasive ventilation (NIV).. Design. Prospective, clinical investigation.. Setting. Intensive care unit of a university hospital.. Patients. Twenty-four patients with acute respiratory failure (ARF).. Intervention. Each patient was studied with a HME and a HH in a random order during two consecutive 20min periods of NIV.. Measurements and results. Respiratory rate (RR), expiratory tidal volume (VTe) and expiratory minute ventilation (VE) were measured during the last 5 min of each period and blood gases were measured. Mean pressure support and positive end-expiratory pressure levels were, respectively, 15±4 and 6±2 cmH2O. VE was significantly greater with HME than with HH (14.8±4.8 vs 13.2±4.3 l/min; p,0.001). This increase in VE was the result of a greater RR for HME than for HH (26.5±10.6 vs 24.1±9.8 breaths/min; p=0.002), whereas the VT for HME was ...
