introduction: finding the probable governing pattern of peep and cvp changes is an area of interest for in-charge physicians and researchers. therefore, the present study was designed with the aim of evaluating the relationship between the mentioned pressures. methods: in this quasi-experimental study, patients under mechanical ventilation were evaluated with the aim of assessing the effect of ...

OBJECTIVE To investigate the effect of different ventilation settings on hemodynamic stability in severe controlled hemorrhagic shock. DESIGN Prospective, randomized, controlled animal study. SETTING Research laboratory in a university hospital. SUBJECTS Approximately 35-45 kg domestic pigs. INTERVENTIONS Twenty-four domestic pigs were bled 45 mL/kg (estimated 65% of their calculated bl...

Twenty two babies receiving artificial ventilator support were studied on 29 occasions to determine the effects of low levels of positive end expiratory pressure. Mean positive end expiratory pressure during these studies was 2.6 cm H2O. Changes in tidal volume, minute volume, compliance, and transcutaneous gas trends produced by the use of positive end expiratory pressure were investigated. Po...

PURPOSE OF REVIEW To compare the positive end-expiratory pressure selection aiming either to oxygenation or to the full lung opening. RECENT FINDINGS Increasing positive end-expiratory pressure in patients with severe hypoxemia is associated with better outcome if the oxygenation response is greater and positive end-expiratory pressure tests may be performed in a few minutes. The oxygenation ...
