A Bird Mark VIII ventilator was modified to produce a simple and inexpensive C.P.P.B. and I.M.V. circuit. A Bain Breathing Circuit allowed the manifold to be placed near the ventilator. The negative pressure and flow to the injector produce C.P.P.B. The continuous flow of the Mapleson D Modification furnished constant inflow to provide humidified fresh gas to the reservoir and the patient circuit for I.M.V. An accompanying graph illustrates suggested flow rates and CO2 elimination (Figure 2).
