Scuba diving (originally the acronym for self-contained scuba, now widely considered as a word) is a form of underwater diving in which divers use a set of scuba breathing apparatus to breathe underwater, while early diving relied entirely on air pumped from the surface. Scuba divers carry their own source of breathing gas (usually compressed air, which makes They have more freedom than with air pipes - surface supply and scuba diving allow divers to stay underwater much longer than with breathing techniques such as snorkeling and free diving. According to the purpose of diving, divers usually move underwater by attaching swimsuits, but the external driving force can come from underwater vehicles or sleds pulled out of the water.

Early diving experimenters soon found that, in addition to normal atmospheric pressure, it was not enough to provide air to breathe comfortably under water. Water exerted more and more pressure on the chest and lungs, per foot per square inch. Therefore, the respiratory pressure inhaled must be almost completely opposite to the surrounding or surrounding pressure to inflate the lungs.

Usually, breathing through pipes more than three feet under water becomes difficult. Modern demand valve regulators provide breathing gas under ambient pressure, ensuring that divers can breathe in and out naturally and almost effortlessly, regardless of depth, because divers' noses and eyes are covered by diving masks, divers cannot breathe through their noses, but dive in full face Except in the case of masks, breathing through the regulator's mouth quickly becomes second nature.

水肺潜水（“Scuba”最初是自给式水下呼吸器的首字母缩写，现在被广泛认为是一个单词）是一种水下潜水的形式，潜水员使用一套水下呼吸器在水下呼吸，而早期的潜水完全依赖于从水面泵出的空气，水肺潜水员携带自己的来源呼吸气体（通常是压缩空气，这使他们比有空气管道时有更大的自由度——水面供应和水肺潜水允许潜水员在水下停留的时间比使用呼吸技术（如浮潜和自由潜水）长得多。根据潜水的目的，潜水员通常通过连接泳裤在水下移动但是外部的推动力可以来自水下航行器，或者从水面上拖出的雪橇。早期潜水实验者很快发现，除了正常的大气压力外，仅仅提供空气在水下舒适地呼吸是不够的，水对胸部和肺脏施加越来越大的压力，每英尺每平方英寸（约巴磅每平方英寸），因此吸入的呼吸压力必须几乎完全与周围或周围的压力相反，以使肺部充气。

通常情况下，通过水下三英尺以上的管子呼吸变得困难现代需求阀调节器提供环境压力下的呼吸气体，确保潜水员可以自然地、几乎毫不费力地吸气和呼气，而不管深度是多少，因为潜水员的鼻子和眼睛被潜水面罩覆盖，潜水员不能通过鼻子呼吸，但戴着全脸潜水面罩的情况除外，从监管者的口中吸气很快就成了第二天性。
