What is a Safety Stop during Scuba Diving?
A safety stop is a voluntary pause during a diver’s ascent, usually lasting around 3 minutes and occurring at a depth of approximately 5 meters (15 feet).

What is a Gas Fraction?
In the context of scuba diving, a gas fraction refers to the proportion of each gas component within a breathing gas mixture. Understanding gas fractions is crucial for divers to ensure safe and efficient breathing under water. The significance of gas fractions cannot be overstated, as they directly influence dive planning, physiological effects on the body, and overall safety. By grasping the fundamentals of gas fractions, divers can make informed decisions that enhance their underwater experience while minimizing risks.
What is Nitrox in Scuba Diving?
What is Nitrox in Scuba Diving? Nitrox, or Enriched Air Nitrox (EANx) or simply EAN, is a breathing gas mixture consisting of nitrogen and oxygen in which the proportion of nitrogen is less than the naturally occurring 78% found in atmospheric air. The primary benefit of using nitrox in scuba diving is reduced nitrogen absorption, […]
What is the No-Decompression Limit (NDL)?
The No-Decompression Limit (NDL) is a fundamental concept in scuba diving, representing the maximum time a diver can spend at a specified depth without the need for mandatory decompression stops during ascent. Understanding and adhering to NDLs is essential for dive planning and ensuring the safety of divers. This entry will explore the concept of NDL, its importance, how it is calculated, and its implications for diving practices.
What is Altitude Diving?
What is Altitude Diving? Altitude diving refers to the practice of scuba diving at locations where the water surface is at an altitude that requires modification of decompression schedules, typically more than about 300 meters (980 feet) above sea level. Altitude diving presents unique challenges for divers, as the reduced atmospheric pressure at higher elevations […]
What is Enriched Air Nitrox (EAN)?
Enriched Air Nitrox (EAN) is a specialized breathing gas mixture used by recreational scuba divers to increase their bottom time or safety margin while diving.
