The so-called P True ________False________ respiratory drive breaking point during a dive is about 55 mm Hg.

Summary Introduction

To review:

Whether the following statement, “The so-called PCO2 respiratory dive breaking point during a dive is about 55mm Hg (millimeter of mercury)” is true or false.

Introduction:

The most popular and simple form of diving is breath-hold diving. This includes holding breath before diving to increase the amount of time for which a diver stays underwater. This generally depends on factors, such as metabolic rate of the diver and the ability of the diver and his body to store and effectively transport O2 (oxygen) and CO2 (carbon dioxide).

Explanation

During the breath-hold dive, the diver should maintain the balance between the levels of O2 and CO2. A certain minimum level of O2 and CO2 with respect to their PaO2 (partial pressure of oxygen) and PACO2 (partial pressure of carbon dioxide) should be optimum with accordance to the optimum partial pressure needed to be maintained in the pulmonary capillaries and the alveoli...
