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 ...
These barriers should provide a one-way filter valve which lets the air from the rescuer deliver to the patient while any substances from the patient (e.g. vomit, blood) cannot reach the rescuer. Many adjuncts are single use, though if they are multi use, after use of the adjunct, the mask must be cleaned and autoclaved and the filter replaced ...
The cervical spine should be stabilized, if possible, by using either manual stabilization of the head and neck by a provider or applying a C-collar. [16] The C-collar can make ventilatory support more challenging and can increase intracranial pressure, therefore is less preferable than manual stabilization. [ 17 ]
Once the oxygen source is depleted, the device can no longer be used because it is driven completely by an oxygen source. The (FROPVD) has a peak flow rate of 100% oxygen at up to 40 liters per minute. To use the device, manually trigger it until chest rise is noted and then release. [2] Wait five seconds before repeating.

The American Heart Association still advocates the use of cricoid pressure during resuscitation using a BVM, and during emergent oral endotracheal intubation. [4] However, recent research increasingly suggests that cricoid pressure may not be as advantageous as once thought.
