What is Ambient Pressure in Scuba Diving?
What is Ambient Pressure in Scuba Diving? Ambient pressure plays a critical role in scuba diving and understanding its effects on the human body is essential for divers’ safety and enjoyment. This entry explores the concept of ambient pressure, its sources, implications for dive planning, and how it influences dive physiology and equipment. Ambient pressure […]
What is an Alternative Air Source?
An alternative air source is an essential piece of safety equipment for scuba divers. In the event of a primary air supply failure or other emergency situations, an AAS allows the diver to access an additional source of breathing gas, providing crucial time to safely ascend to the surface. By ensuring divers have an alternative air source, the risk of drowning or other serious accidents is significantly reduced.
What is a Yoke Valve?
A yoke valve or fitting is a critical component in scuba diving, serving as the connection between a regulator or filling whip and a diving cylinder.
What is a Y-Valve?
What is a Y-Valve? Y-valves, also known as dual orifice valves, are an essential piece of equipment for scuba diving enthusiasts and professionals alike. These specialized valves allow divers to connect two regulators to a single cylinder, providing an increased level of safety and convenience. In this encyclopedia entry, we will explore the function and […]
What is Anoxia?
What is Anoxia? Anoxia, a medical condition characterized by an acute deficiency of oxygen in the body, is a critical concern for scuba divers. It can occur due to various reasons and poses severe risks to divers’ health and safety. In the context of scuba diving, it is essential to understand the causes, symptoms, and […]
What is a Yoke Adapter?
What is a Yoke Adapter? The scuba diving world is filled with an array of equipment designed to facilitate the underwater experience. One crucial piece of equipment that often goes unnoticed is the yoke adaptor. This seemingly small component is an essential part of the scuba diving setup, allowing divers to connect their regulators or […]
What is a Scuba Diving Regulator?
What is a Scuba Diving Regulator? A regulator is a fundamental and essential piece of equipment in scuba diving, responsible for managing the delivery of breathing gas from the scuba tank to the diver. The primary function of the regulator is to reduce the high pressure of the compressed air or mixed gas in the […]
What is a First Stage when Scuba Diving?
The first stage is a vital component of the diving regulator, as it is responsible for reducing high-pressure gas from the tank and delivering it to the second stage and buoyancy compensator (BC)
What is a Second Stage in Scuba Diving?
The second stage regulator, also known as the demand valve, is an essential component in a scuba diver’s breathing apparatus. It is responsible for delivering air from the first stage regulator (connected to the scuba cylinder) to the diver’s mouth at a pressure that matches the surrounding water pressure, also known as ambient pressure.
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.
