Biphasic cuirass ventilation (BCV) represents a sophisticated approach to negative pressure ventilation, employing an external ventilator in the design of a cuirass to facilitate both inspiratory and expiratory phases across a range of cycle rates and pressures. The way Biphasic Cuirass Ventilation (BCV) operates is by assisting the lungs’ normal function. During the inhalation process, our respiratory muscles contract, causing our chest wall to expand and our diaphragm to flatten, thereby allowing air to enter our lungs. As we exhale, these muscles relax, thereby expelling air from our lungs. As a noninvasive method of ventilation, BCV replicates this process to support those who require breathing assistance for either an acute or chronic condition.
