INTRODUCTION: It is estimated that 121,000 people are awaiting organ transplant while there are 13,700 listed donors. Brain death donors make up the overwhelming majority of the donor pool as opposed to cardiopulmonary death donors because of the relatively preserved oxygenation. We illustrate the role of high-frequency percussive ventilation (HFPV) by volumetric diffusion respirator (VDR) as a bridge to procurement in donors with hypoxemic respiratory failure who have failed traditional ventilator. HFPV delivers pneumatically powered, time cycled, pressure limited, flow-interrupted breaths. The diffusive and convective effects of the percussive air flow create biphasic oscillations that generates countercurrent flow of gas, facilitating removal of intrapulmonary secretions, displacement of trapped gas and recruitment of the lung is achieved through improved intrapulmonary diffusion allowing for better gas exchange (Figure 1). We present a case where HFPV improved donor’s oxygenation, thus allowing time for successful procurement of donor organs.
