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.
The jacket ventilator, also known as a poncho or raincoat ventilator, is a lighter version of the iron lung or the cuirass ventilator, constructed of an airtight material (such as plastic or rubber) arranged over a light metal or plastic frame, or screen, and depressurized and repressurized by a portable ventilator.

Mechanical ventilation or assisted ventilation is the medical term for using a ventilator machine to fully or partially provide artificial ventilation.Mechanical ventilation helps move air into and out of the lungs, with the main goal of helping the delivery of oxygen and removal of carbon dioxide.
Inserting a tube that is too large relative to the diameter of the trachea can cause swelling. Conversely, inserting a tube that is too small can result in inability to achieve effective positive pressure ventilation due to retrograde escape of gas through the glottis and out the mouth and nose (often referred to as a "leak" around the tube).
An open-source ventilator is a disaster-situation ventilator made using a freely-licensed design, and ideally, freely-available components and parts. Designs, components, and parts may be anywhere from completely reverse-engineered to completely new creations, components may be adaptations of various inexpensive existing products, and special ...
A tracheostomy tube or endotracheal tube with a 6 or 7 mm internal diameter is then inserted, the cuff is inflated, and the tube is secured. The person performing the procedure might utilize a bougie device, a semi-rigid, straight piece of plastic with a 25-mm tip at a 30-degree angle, to provide rigidity to the tube and assist with guiding its ...
The respirator had a cylinder to determine the amount of air, and a pump. A tube was inserted into the patient's trachea, a small balloon was inflated as a seal around the tube, and then the respirator pumped air into the lungs. The amount of air and the amount per unit of time was set with a knob. Engström patented the respirator in 1950. [10]
Intubation (sometimes entubation) is a medical procedure involving the insertion of a tube into the body. Patients are generally anesthetized beforehand. Examples include tracheal intubation , and the balloon tamponade with a Sengstaken–Blakemore tube (a tube into the gastrointestinal tract ).
