International Pumping Systems 313 Heinz Rd., Dearborn, MI 48124 To: B. Franklin, P.E., Consulting Division Manager International Pumping Systems 313 Heinz Rd., Dearborn, MI 48124 From: L.A. Larson, Project Manager Date: 11/14/2011 Re: Motor Sizing for Oxygen Pressure Control Dist: H.L. Smith, M.D., Director of Research, Respiration Division Our company is currently developing a new type of oxygen delivery system for emergency response personnel, and we require an expert opinion on how to size our pumping components. Existing protocols for oxygen delivery typically call for a fixed flow rate of oxygen to the patient, with manual pressure on a breathing mask or oxygen bag used to adjust pressure. We believe that for certain medical conditions where the patient is clearly conscious and responsive, more benefit may be obtained if an oxygen supply is maintained at slightly elevated pressures, but with flow rate variable according to the patient’s own activity.
