What is physiological PEEP ____ and what does it do?
|
|
1-2 cm H20; Maintain alveoli patency
|
|
|
6-10 cmH20; increase Tidal volume
|
|
|
3-5 cm H20; push oxygen down to the lungs
|
|
|
3-5 cm H20; maintain alveoli patency
|
Explanation:
Detailed explanation-1: -The bottom line on PEEP is that it increases airway pressure. This improves alveolar recruitment (or the total number of alveoli open and participating in gas exchange) and improves oxygenation.
Detailed explanation-2: -Respiratory effects of positive pressure ventilation: By increasing FRC, PEEP: Increases alveolar recruitment, which gives rise to: Improved V/Q matching. Increased total gas exchange surface.
