Positive pressure ventilation is a technique in which large fans (usually gasoline powered, but sometimes electric) are used to force air through a structure for extremely fast ventilation. This creates a much higher pressure inside the structure than what exists outside thereby pushing the smoke and heat outside.
Provision of oxygen under pressure by a mechanical respirator.
A type of assisted breathing where air, frequently mixed with increased amounts of oxygen, is delivered under pressure by a mechanical respirator.
process of forcing gases down a patient's trachea using either a manual control technique or using an automatic ventilator. PPV can be done using a manual resuscitator or the rebreathing bag on the anesthesia machine; for long term use an automatic ventilator is usually prescribed.
(PPV): Ventilation of an area by the use of a fan to push clean air into that space and controlled use of openings for the escape of smoke and gasses.
Positive Pressure ventilators help patients with respiratory problems to breathe easier. They use high pressure gas at the opening of the patients lungs in order to mobilize oxygen flow down the pressure gradient, and into the patient's lungs.
