Abstract Background CPAP is characterized by the application of a constant and continuous positive pressure into patient’s airway. By delivering during both inspiration expiration, increases functional residual capacity opens collapsed or under ventilated alveoli, thus decreasing right to left intrapulmonary shunt improving oxygenation in obese individuals. Main body abstract Obesity several al...

To the Editor: We have read with interest the RESPIRATORY CARE article entitled “Use of high-flow nasal cannula oxygen therapy in subjects with ARDS: a 1-year observational study”.1 We are surprised that, compared with an overall mortality of 29%, the mortality in the group treated with high-flow nasal cannula (HFNC) oxygen therapy and subsequently needing intubation was 50%. This is close to t...

H epatopulmonary syndrome (HPS) occurs in the setting of liver disease when oxygenation is impaired as a result of intrapulmonary vascular dilatation. The exact mechanism is not entirely clear, but is felt to be related to increases in pulmonary vasodilators, such as nitric oxide. Diagnosis requires the presence of liver disease, inadequate oxygenation, and confirmation of intrapulmonary shunti...

conclusions: in the present study, applying positive airway pressure methods (cpap or imv) during cpb was associated with better postoperative abg measurements and (a-a) do2. results: the demographic data were similar in between three groups. graft number, pump time and preoperative abgs were not significantly different. postoperative pao2 were significantly higher in the cpap and imv groups an...

In 10 patients undergoing ventilation, venous admixture was measured at different values of positive end-expiratory pressure (PEEP). The measurements were performed at the level of fractional inspired oxygen (FIO2) at which each patient was ventilated, and at FIO2=1. In patients ventilated at FIO2 between 0.21 and 0.3 venous admixture was not modified by PEEP, while in patients ventilated with ...

BACKGROUND Atelectasis may occur and ventilation-perfusion mismatch may increase during general anaesthesia with neuromuscular paralysis and mechanical ventilation, though preservation of some intermittent muscle contraction might mitigate this process. There is still no ideal manoeuvre to minimize such mismatch or atelectasis. Bi-level positive airway pressure (BiPAP) ventilation adjusts to ex...

Hepatopulmonary syndrome is a rare complication of liver disease and portal hypertension. It has not been previously described in medical literature Nigeria. We report this case 64-year-old man who presented with 3 months’ history recurrent breathlessness, platypnoea leg swelling. He had diagnosed cirrhosis variceal band ligation 2018, managed for 2 episodes hepatic encephalopathy prior to refe...

INTRODUCTION Acute lung injury (ALI) can result from various insults to the pulmonary tissue. Experimental and clinical data suggest that spontaneous breathing (SB) during pressure-controlled ventilation (PCV) in ALI results in better lung aeration and improved oxygenation. Our objective was to evaluate whether the addition of SB has different effects in two different models of ALI. METHODS F...
