A<unk>  (FROPVD), also referred to as a manually triggered ventilation<unk>  (MTV), is used to assist ventilation in apneic or hypoventilating patients, although these<unk> s can also be used to provide supplemental<unk>  to breathing patients. It can be used on patients with spontaneous breaths, as there is a valve that opens automatically on inspiration. When ventilating a patient with a (FROPVD) you must ensure an adequate, constant<unk>  supply is available. Once the<unk>  source is depleted, the<unk>  can no longer be used because it is driven completely by an<unk>  source. The (FROPVD) has a peak<unk>  rate of 100%<unk>  at up to 40 liters per minute. To use the<unk> , manually trigger it until chest rise is noted and then release. Wait five seconds before repeating. The<unk>  must have a pressure relief valve that opens at 60cm of water pressure to avoid over ventilation and trauma to the lungs. The (FROPVD) is contraindicated in adult patients with potential chest trauma and all children. 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<unk> s. The main components of<unk> s include * An inspiratory pressure safety release valve. * A trigger or level positioned to allow both hands to remain on the mask to provide an airtight seal while supporting and tilting the patients head. * A peak<unk>  rate of 100%<unk>  at up to 40 L/min. * An audible alarm that goes off when the relief valve pressure is exceeded.
