Resuscitators Information

Resuscitators are medical devices which use positive pressure to manually respirate patients who have compromised breathing. Lungs expel the air due to their natural elasticity. These devices are typically temporary implements until the patient can be transferred to a medical ventilator. Resuscitators are much smaller than ventilators, making them effective for emergency medical treatment.

There are three types of resuscitators. Manual resuscitators require an individual to intermittently compress and decompress a handheld bag that is connected to a face mask. Self-inflating resuscitators have an air inlet valve to refill the bag, and an oxygen inlet valve which draws O2 from a reservoir. An individual must still compress the bag to initiate respiration. Finally, gas-powered resuscitators are driven by pressurized gas delivered to a regulator.
