True statement regarding ‘prone position’ ventilation in a polytrauma patient with ARDS:
Correct Answer: Should be tried for 6 -8 hours
Description: - Prone ventilation is not a mode of ventilation - Means patient put on prone position and ventilated Prone position ventilation- Has improved oxygenation of patient- Cannot be tried for long hours- Practiced when moderate or severe ARDS is suspected in patient- When patient put in prone way the dorsal surface of the lung also gets a uniform perfusion- So, the area of V/P mismatch is very much minimized in prone position- Decrease ventilation lung injury because venous drainage is good, lymphatic drainage is good, pressure on alveoli minimized The prone position has been utilized to improve respiratory function in patients with adult respiratory distress syndrome (ARDS). In anesthetized patients, the prone position has advantages over the supine position with regard to lung volumes and oxygenation without adverse effects upon respiratory mechanics. This benefit has also been demonstrated in obese and pediatric patients When patients are prone, weight should be distributed to the thoracic cage and bony pelvis, allowing the abdomen to move with respiration.
