A Bird Mk. 8 respirator has been modified to permit the use of PEEP, CPAP and IMV. Gas supply is from an oxygen blender to allow easy adjustment of the inhaled oxygen concentration. A special fitting was made to mount a flow meter which supplies the IMV reservoir. PEEP is generated by the Mk. 8 negative pressure generator mounted in opposition to exhalation and its magnitude can be adjusted by the negative pressure control of the respirator. This modified machine is simple, reliable and relatively inexpensive.
