Chapter 13, Problem 13.50P

Interpretation Introduction

Interpretation:

The reason for the treatment of respiratory problems with devices that deliver air with a higher partial pressure of ${\text{O}}_2$ than normal air is to be determined.

Concept introduction:

The partial pressure is the pressure that is exerted by the gas in a mixture if it was supposed to occupy the same volume as the mixture acquires at the same temperature. It is the measure of the thermodynamic activity of the gas molecules. It is represented by $P$. It is used to determine the blood levels of oxygen and carbon dioxide. The total pressure of the mixture of gas is the sum of partial pressures of the individual gases.

Respiratory problem is the medical condition due to which the organs and tissues that make gas exchange difficult are affected. It includes various diseases such as asthma, lung stiffness, common cold, pneumonia, and lung cancer.
