A liquid ventilator is similar to a medical ventilator except that it should be able to ensure reliable total liquid ventilation with a breatheable liquid (a perfluorocarbon). [ 1 ] [ 2 ] Liquid ventilators are prototypes that may have been used for animal experimentations but experts recommend continued development of a liquid ventilator ...
Although total liquid ventilation (TLV) with completely liquid-filled lungs can be beneficial, [9] the complex liquid-filled tube system required is a disadvantage compared to gas ventilation—the system must incorporate a membrane oxygenator, heater, and pumps to deliver to, and remove from the lungs tidal volume aliquots of conditioned perfluorocarbon (PFC).

Artificial ventilation or respiration is when a machine assists in a metabolic process to exchange gases in the body by pulmonary ventilation, external respiration, and internal respiration. [1] A machine called a ventilator provides the person air manually by moving air in and out of the lungs when an individual is unable to breathe on their own.

A liquid cooling and ventilation garment (LCVG) has additional crush-resistant ventilation ducts, which draw moist air from the wearer's extremities, keeping the wearer dry. In a fully enclosing suit where exhaled breathing air can enter the suit, the exhaled air is moist and can lead to an uncomfortable feeling of dampness.
The interior of the Apollo PLSS Diagram of the A7L PLSS and OPS, with interfaces to the astronaut and the Lunar Module cabin. The portable life support system used in the Apollo lunar landing missions used lithium hydroxide to remove the carbon dioxide from the breathing air, and circulated water in an open loop through a liquid-cooled garment, expelling the water into space, where it turned ...
Techniques might include head and neck maneuvers to optimize ventilation, abdominal thrusts, and back blows. Advanced techniques require specialized medical training and equipment, and are further categorized anatomically into supraglottic devices (such as oropharyngeal and nasopharyngeal airways ), infraglottic techniques (such as tracheal ...
