The fundamental item of diving equipment used by divers other than freedivers, is underwater breathing apparatus, such as scuba equipment, and surface-supplied diving equipment, but there are other important items of equipment that make diving safer, more convenient or more efficient.
Dräger Fabius Tiro Anaesthetic machine Draeger Evita v500 respirator. Arrow indicates Neoflow air flow sensor. Dräger Medical is a manufacturer of medical equipment. The company offers products and services including Emergency Care, Perioperative Care, Critical Care, Perinatal Care and Home Care.
They may have manual backup mechanisms to enable hand-driven respiration in the absence of power (such as the mechanical ventilator integrated into an anaesthetic machine). They may also have safety valves, which open to atmosphere in the absence of power to act as an anti-suffocation valve for spontaneous breathing of the patient.
Draeger Ray dive/surface valve with bite grip scuba mouthpiece, non-return valves, and breathing hoses. A breathing hose or sometimes breathing tube on a rebreather is a flexible tube for breathing gas to pass through at ambient pressure. They are distinguished from the low-, intermediate-, and high-pressure hoses which may also be parts of ...
manual ventilation Bain circuit: respiratory maintenance circuit Laryngoscope: used to view larynx including the vocal cords, the glottis, etc. Endotracheal tube: a tube introduced into the patient's trachea to maintain a patient to ensure that air reaches the lungs for respiration: Laryngeal mask airway (LMA)
This is a form of back-pressure regulator. The supply of gas for inhalation is through a demand valve which works on the same principles as a regular diving demand valve second stage. Like any other breathing apparatus, the dead space must be limited to minimise carbon dioxide buildup in the mask. [citation needed]
A resuscitator is a device using positive pressure to inflate the lungs of an unconscious person who is not breathing, in order to keep them oxygenated and alive. [citation needed] There are three basic types: a manual version (also known as a bag valve mask) consisting of a mask and a large hand-squeezed plastic bulb using ambient air, or with supplemental oxygen from a high-pressure tank.
Some types are also referred to as a compressed air breathing apparatus (CABA) or simply breathing apparatus (BA). Unofficial names include air pack, air tank, oxygen cylinder or simply pack, terms used mostly in firefighting. If designed for use under water, it is also known as a scuba set (self-contained underwater breathing apparatus).
