Respiratory protective devices - Human factors - Part 3 : Physiological responses and limitations of oxygen and limitations of carbon dioxide in the breathing environment

This document gives:a description of the composition of the Earth's atmosphere;a description of the physiology of human respiration;a survey of the current biomedical literature on the effects of carbon dioxide and oxygen on human physiology;examples of environmental circumstances where the partial pressure of oxygen or carbon dioxide can vary from that found at sea level.This document identifies oxygen and carbon dioxide concentration limit values and the length of time within which they would not be expected to impose physiological distress. To adequately illustrate the effects on human physiology, this document addresses both high altitude exposures where low partial pressures are encountered and underwater diving, which involves conditions with high partial pressures. The use of respirators and various work rates during which RPD can be worn are also included.

Sumary
Respiratory protective devices - Human factors - Part 3 : Physiological responses and limitations of oxygen and limitations of carbon dioxide in the breathing environment

This document gives:

  • a description of the composition of the Earth's atmosphere;
  • a description of the physiology of human respiration;
  • a survey of the current biomedical literature on the effects of carbon dioxide and oxygen on human physiology;
  • examples of environmental circumstances where the partial pressure of oxygen or carbon dioxide can vary from that found at sea level.

This document identifies oxygen and carbon dioxide concentration limit values and the length of time within which they would not be expected to impose physiological distress. To adequately illustrate the effects on human physiology, this document addresses both high altitude exposures where low partial pressures are encountered and underwater diving, which involves conditions with high partial pressures. The use of respirators and various work rates during which RPD can be worn are also included.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
