The difference between the alveolar pressure and the pleural pressure is called the

A. transpulmonary pressure.

B. transthoracic pressure.

C. driving pressure.

D. transrespiratory pressure.

Summary Introduction

Introduction:

Alveolar pressure is the pressure inside the alveoli of the lungs and it plays a key role during inspiration. The alveolar pressure decreases during inspiration due to the expansion of the lungs to a value lower than atmospheric pressure. This results in the movement of air into the lungs. The pleural pressure refers to the pressure within the pleural cavity, which is also slightly less than the atmospheric pressure and is termed as negative pressure. The alveolar pressure of the lungs is always greater than the pleural pressure in case of normal lungs, which is also necessary for maintaining the inflated state of the lungs.

Explanation

Justification/ Explanation for the correct answer:

Option (a) is transpulmonary pressure. The difference between the alveolar pressure (Pal) and the pleural pressure (Ppl) is called the transpulmonary pressure Transpulmonary pressure can be measured using pressure transducers and represented as Ptp. It increases when there is an increase in alveolar pressure (Palv) during inspiration. Hence, option (a) is correct.

The explanation for the incorrect answers:

Option (b) is transthoracic pressure. The transthoracic pressure is the difference between the alveolar pressure and the body surface pressure and is represented as Ptt. It measures the pressure difference across the lungs...
