The BVM consists of a flexible air chamber (the "bag", roughly 30 cm in length), attached to a face mask via a shutter valve. When the face mask is properly applied and the "bag" is squeezed, the device forces air through into the patient's lungs; when the bag is released, it self-inflates from its other end, drawing in either ambient air or a ...
The well-known Bag Valve Mask (BVM) quickly became the core functional component of their design, [19] with the goal of utilizing 3D printed and traditionally manufactured components for localized assembly of the systems to maximise potential manufacturing capabilities around the globe.
Note: ( In cases with an apneic patient the best results will be achieved using the Two person bag-valve-mask technique.) Proper training and considerable practice is required to correctly use the FROPVD devices. [3] The main components of flow-restricted, oxygen-powered ventilation devices include An inspiratory pressure safety release valve.
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.
Pocket Masks are used to provide rescue breaths similar to a bag valve mask, but the rescuer is using their own breath instead of a bag. The device consists of a mask attached to a one-way filter valve. The filter valve prevents bodily fluids such as blood vomit from entering the rescuer's mouth. The mask is secured to the face with both hands ...
An open circuit SCBA typically has three main components: a high-pressure gas storage cylinder, (e.g., 2,216 to 5,500 psi (15,280 to 37,920 kPa), about 150 to 374 atmospheres), a pressure regulator, and a respiratory interface, which may be a mouthpiece, half mask or full-face mask, assembled and mounted on a framed carrying harness.

Simple orinasal face mask for oxygen therapy at normal atmospheric pressure CPR pocket mask Bag valve mask. Part 1 is the flexible mask to seal over the patients face, part 2 has a filter and valve to prevent backflow into the bag itself (prevents patient deprivation and bag contamination) and part 3 is the soft bag element which is squeezed to expel air to the patient
A PAPR, gown, and biosafety cabinet in use in a BSL-3 laboratory. All parts of the PAPR are visible: the waist unit holding the fan, filter, and battery; the hose; and the mask, in this case a flexible, loose-fitting one. A powered air-purifying respirator (PAPR) is a type of respirator used to safeguard workers against contaminated air.
