Everything about Resuscitator totally explained
A
resuscitator is a device using positive pressure to inflate the lungs of an
unconscious person who is
not breathing, in order to keep him
oxygenated and alive. 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. The second type is a
pulmonary or breath powered resuscitator. The first po the second type was the White Pulmonay Resuscitator or W.P.R. introduced in
1981. The third type is an
oxygen powered resuscitator. These are driven by pressurized gas delivered by a regulator, and can either be automatic or manually controlled. The most popular type of gas powered resuscitator are Time Cycled, Volume Constant Ventilators. In the early days of pre-hospital emergency services, pressure cycled devices like the Pulmotor were popular but yielded less than satisfactory results. One of the first modern resuscitation ventilators was the HARV, later called the PneuPac 2R or Yellow Box. The workings of most modern resuscitators are arranged so that the patient will be able to breathe on his own on should he resume the ability to do so. All resuscitation devices should be able to deliver >85% oxygen when a gas source is available.
Response Considerations
A manual resuscitator should be used on a victim only in an environment where the air is unquestionably safe to breathe.
Spelling
The misspelling
rescuscitator is often encountered, due in no small part to the device being an important piece of
rescue equipment.
