dc.description.abstractThe use of current devices for 'bagging' patients presents two hazards: peak inflation pressure cannot be regulated or measured, and therefore barotrauma could result and hypoxia secondary to inadequate ventilation is a distinct possibility. A pressure regulated lung expansion device with controlled oxygen concentration has been developed. The device was tested on 19 patients who were ventilated on pressure cycled ventilators in surgical and medical intensive care units. Tidal volumes were measured and arterial blood samples were analysed before and after treatment. With the ventilation settings the same before and after treatments, the tidal volumes showed a clinically significant increase (21.6%). Arterial blood gas analysis showed a mean increase in arterial oxygen concentration of 1.3% indicating that no significant hypoxia resulted from the procedure. Arterial carbon dioxide concentration showed a mean increase of 7.1% indicating slight underventilation during the procedure.
