An Ambu bag is a self-inflating bag resuscitator from Ambu A/S, which still manufactures and markets self-inflating bag resuscitators. [citation needed] Today there are several manufacturers of self-inflating bag resuscitators. Some, like the original Ambu bag, are durable and intended for reuse after thorough cleaning.
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.
Non-rebreather mask covering a woman's nose and mouth. The non-rebreather mask covers both the nose and mouth of the patient and attaches with the use of an elastic cord around the patient's head. The NRB has an attached reservoir bag, typically one liter, that connects to an external oxygen tank or bulk oxygen supply
A non-rebreather mask (NRB) is a device used to deliver supplemental oxygen to a spontaneously breathing person. An NRB allows the delivery of relatively high concentrations of oxygen while using a constant flow rate, with relatively low waste, by accumulating the oxygen flow during exhalation in a soft bag, to be inhaled at the start of the ...
The B circuit is not in clinical use, but the C circuit is commonly used during patient transfer and in resuscitation as it is compact. The Waters bag, developed by Ralph Waters, comprises a C system with an attached soda lime absorption canister to remove exhaled carbon dioxide, meaning that exhaled gases can safely be rebreathed.
Both rebreather and open circuit equipment have been used in this application, where either pure oxygen or supplemental oxygen is provided by the equipment. Minor leakage in either direction usually only affects efficiency and gas endurance, as the ambient air is usually only hypobaric due to low ambient pressure.
The bags along either side of the chest unit cool the air mixture before inhalation and is a surprisingly effective system, with the air being quite cool when entering the face mask. [clarification needed] There is a 60-minute timer at the top of the chest unit which, during the fighting of a casualty, [clarification needed] is set for only 45 ...
Non-rebreather mask, an oro-nasal mask used in medicine to assist in the delivery of oxygen therapy; Oxygen mask, which covers the mouth and nose of a patient undergoing oxygen therapy as first aid or longer-term treatment, or a passenger in an aircraft which has depressurised at altitude; Continuous positive airway pressure mask; Anesthetic mask
