Question

To prevent atelectasis and improve gas exchange, most thoracic surgery patients placed on ventilatory support receive which of the following?

A) 0 cm H2O PEEP

B) 5 cm H2O PEEP

C) 8 cm H2O PEEP

D) 10 cm H2O PEEP

Answer 1

The most appropriate PEEP level for thoracic surgery patients on ventilatory support is 8 cm H2O PEEP.

Step-by-step explanation:

The most appropriate positive end-expiratory pressure (PEEP) level for thoracic surgery patients placed on ventilatory support to prevent atelectasis and improve gas exchange is 8 cm H2O PEEP (Option C). PEEP is a technique that keeps the airways open and helps maintain lung volume during mechanical ventilation. It improves gas exchange by preventing collapse of the alveoli and maintaining a positive pressure at the end of expiration.
