Intermittent positive pressure breathing (IPPB) is a respiratory therapy treatment for people who are hypoventilating. While not a preferred method due to cost, [ 1 ] IPPB is used to expand the lungs, deliver aerosol medications, and in some circumstances ventilate the patient.
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.
Puritan Bennett has been a provider of respiratory products since 1913 originally as a medical gas supplier. In addition to critical care ventilation, Puritan Bennett provided medical devices for patients outside of the acute care environment.
It is negative pressure ventilator, a mechanical respirator which encloses most of a person's body, and varies the air pressure in the enclosed space, to stimulate breathing. [ 6 ] [ 7 ] It assists breathing when muscle control is lost, or the work of breathing exceeds the person's ability suffering from polio and botulism and certain poisons ...
If 'transpulmonary pressure' = 0 (alveolar pressure = intrapleural pressure), such as when the lungs are removed from the chest cavity or air enters the intrapleural space (a pneumothorax), the lungs collapse as a result of their inherent elastic recoil. Under physiological conditions the transpulmonary pressure is always positive; intrapleural ...
The therapy is an alternative to positive end-expiratory pressure (PEEP). Both modalities stent open the alveoli in the lungs and thus recruit more of the lung surface area for ventilation. However, while PEEP refers to devices that impose positive pressure only at the end of the exhalation , CPAP devices apply continuous positive airway ...

negative pressure breathing 1. (medical) Ventilation in which the surface of the thorax is exposed to pressure below the ambient pressure during inspiration. Used as a method of artificial respiration (iron lung). [45] 2. (diving) Breathing where the pressure of the breathing gas at the mouth is lower than the ambient pressure at the thorax.
