Textbook Problem

# At sea level, a diver has the following:•Lung volume: 6 L•Pressure within the lungs: 755 mm HgIf this individual dives to a depth of 99 feet and compresses the lung volume to 2 L, what will be the pressure within the diver's lungs?A. 960 mm HgB. 1420 mm HgC. 1765 mm HgD. 2265 mm Hg

Summary Introduction

Introduction:

Environments with high pressure have a considerable effect on the cardiopulmonary system of the body. The ambient pressure with which the diver is surrounded includes the atmospheric pressure and the hydrostatic pressure. The pressure experienced is calculated by Boyle’s law, which governs the compression in the lungs when a diver descends.

Explanation

Option (d) is given as 2265 mm Hg.

Given,

Lung volume (V1) = 6L

The pressure at lung volume V1 (P1) = 755 mm Hg

At 99 feet, the lung volume (V2) = 2L

So,

P1V1=P2V2P2=P1V1V2=755
