What is the primary purpose of PAM in diving?

The primary purpose of Pressure Adjustment Maintenance (PAM) in diving is focused on the safety and health of divers. Testing a diver's air for harmful gases is crucial to ensure that they are breathing safe and breathable air while underwater. Contaminants or toxic gases in a diver's air supply can lead to serious health risks, including hypoxia or other respiratory issues, which can be fatal in an underwater environment. Therefore, regularly checking and analyzing the air quality helps maintain the safety of the diving operation.

This understanding highlights the significant role of air quality as a fundamental aspect of dive safety, making the air testing process essential in preventing potential hazards related to air contamination during dives.
