Question

In the context of mechanical ventilation, identify the correct pressure components:

a. Transthoracic pressure
b. Transpulmonary pressure
c. Static pressure
d. Dynamic pressure

Answer 1

The correct pressure components in mechanical ventilation are transthoracic pressure, transpulmonary pressure, static pressure, and dynamic pressure.

Step-by-step explanation:

In mechanical ventilation, the correct pressure components are:

1. Transthoracic pressure: This is the pressure inside the chest cavity.
2. Transpulmonary pressure: This is the difference between the intra-alveolar (intrapulmonary) pressure and the intrapleural pressure. It determines the size of the lungs and prevents them from collapsing.
3. Static pressure: This is the pressure exerted by gases present in the environment.
4. Dynamic pressure: This is the pressure created by the movement of gases, such as during breathing.
