I. GENERAL INFORMATION
A. Initial Inspection
An initial inspection should be performed on the PD1000 as soon as possible after receipt. When removed from
carton, an inspection should be made for any damage due to shipping. If shipping damage has occurred, call
DeVilbiss Healthcare at 800-338-1988 (814-443-4881) for replacement instructions.
B. Maintaining the PD1000
The PD1000 should be periodically maintained according to the guidelines set forth in Section IV. Maintenance, and
testing should only be done by qualied service personnel. Failure to follow the procedures set forth in this manual
may void the warranty.
C. General Description
The PD1000 PulseDose system delivers a pulse or "bolus" of oxygen at the leading edge of inspiration. This bolus is
delivered at both the proper ow and volume so that it is delivered deep into the lungs where gas exchange takes
place. The PD1000 PulseDose is rate responsive from 6 BPM to 40 BPM.
II. THEORY OF OPERATION
The PD1000 utilizes a vacuum switch to detect the negative pressure at the beginning of each inspiration
(approximately .1 inches water column due to inhalation). That, in turn, opens the solenoid for a time interval that
corresponds to the ow rate selected on the rotary selector. At higher ow rates, the valve is open longer resulting in
increased pulse volumes.
Atmospheric pressure compensation occurs automatically because the pressure side of the vacuum switch is open
to atmosphere.
All PD1000 units are set on 2 liters per minute continuous ow from the factory. Changing to a different continuous
ow rate involves changing the cannula tting as outlined in Section VI, D.
The PD1000 delivers 16.5 cc 0
2
per setting number (i.e. setting 2 = 33cc 0
2
).
