A bag valve mask (BVM), sometimes known by the proprietary name Ambu bag or generically as a manual resuscitator or "self-inflating bag", is a hand-held device commonly used to provide positive pressure ventilation to patients who are not breathing or not breathing adequately.
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.
A ventilated balance enclosure Vented balance safety enclosures are used in pharmaceutical, chemical, biological, and toxicological laboratories to provide maximum containment for weighing operations in weighing scales .
Ventilators may be computerized microprocessor-controlled machines, but patients can also be ventilated with a simple, hand-operated bag valve mask. Ventilators are chiefly used in intensive-care medicine, home care, and emergency medicine (as standalone units) and in anesthesiology (as a component of an anesthesia machine).
Medical students demonstrate the use of a portable hyperbaric bag. A portable hyperbaric bag, of which one brand is the Gamow (pronounced) bag, is an inflatable pressure bag large enough to accommodate a person. The patient can be placed inside the bag, which is then sealed and inflated with a foot pump.
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. Mapleson D systems are inefficient for spontaneous ventilation due to needing high gas flows to prevent rebreathing, but are efficient for ...
