Summary Introduction
To determine:
The false statement in case a person were to dive with scuba equipment to a depth of 66 feet.
Introduction:
The concentration of gases in the blood and plasma depends on various factors. There will be a change in the plasma concentration of gases because of an alteration in the atmospheric pressure, partial pressure of gases and temperature. With an increase or decrease in the altitude from the sea level, the atmospheric pressure of gases changes and so does the plasma concentration of gases.
