WebJay M. Wilson, John W. DiFiore, in Pediatric Surgery (Seventh Edition), 2012 Adjusting the partial pressure of oxygen. In most conditions requiring mechanical ventilation, patchy atelectasis, caused by a drop in FRC toward closing capacity, results in a significant intrapulmonary shunt that is relatively insensitive to increases in F i O 2.Recruitment of …
WebProne positioning can be used in mechanically ventilated patients with severe hypoxic respiratory failure to optimise oxygenation. most studied in patients with acute respiratory distress syndrome (ARDS) where short lived improvements in oxygenation are common (70%) and sometimes dramatic (e.g. Gattinoni et al, 2001). WebSep 28, 2024 · Summary. The main function of the respiratory system is gas exchange (O 2 and CO 2 ). Ventilation is the movement of air through the respiratory tract into (inspiration) and out of (expiration) the respiratory zone ( lungs ). The. physiologic dead space. is the volume of inspired air that does not participate in gas exchange.
