• A ventilator is a piece of medical era that provides mechanical air flow via transferring breathable air into and out of the lungs, to deliver breaths to a patient who’s physically not able to respire, or respiratory insufficiently. Ventilators are computerized microprocessor-managed machines, however patients can also be ventilated with a simple, hand-operated bag valve masks. Ventilators are mainly used in extensive-care remedy, domestic care, and emergency medicine (as standalone units) and in anesthesiology (as a component of an anesthesia system).

• Ventilators are now and again referred to as “respirators”, a time period usually used for them within the Fifties (mainly the “Bird respirator”). However, cutting-edge sanatorium and clinical terminology uses the word “respirator” to refer instead to a face-mask that protects wearers towards unsafe airborne materials.
