Why is the “minimum manifold pressure” important in diving?

The concept of "minimum manifold pressure" in diving is crucial for maintaining an adequate air supply. In a diving system where multiple tanks are connected, often through a manifold system, this pressure is indicative of the tank pressure required to ensure that divers have sufficient air throughout their dive. If the manifold pressure drops below this minimum threshold, it can signal that there may not be enough gas available to support safe diving, leading to potential risks of running out of air or facing breathing difficulties.

Thus, understanding the minimum manifold pressure is vital for divers to effectively monitor their air supply and make informed decisions during their dive, ensuring safety and adherence to diving protocols.
