All of the following are indications of PEEP, except:
|C||Interstitial lung disease|
|D||To decrease bleeding in thoracic surgery|
|E||Expansion of atelectatic lung|
Interstitial lung disease
Positive end expiratory pressure is the positive pressure given at end expiration.
This positive pressure will prevent the collapse of alveoli during expiration facilitating more oxygen diffusion through alveolar capillary membrane.
So PEEP is useful in conditions like ARDS and pulmonary edema where oxygen transfer along alveolar capillary membrane is impaired.
Positive pressure expands atelectatic lung and decreases bleeding from thorax by causing tamponade.
