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 qualied 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 02 per setting number (i.e. setting 2 = 33cc 02).

INSTALLATION AND OPERATION

III. INSTALLATION AND OPERATION

A. Installation

The PD1000 utilizes a rotary selector that has three
modes for use by the patient. Those modes are: OFF,
"PulseDose", and Continuous Flow. The PD1000 is
battery operated and is turned off by turning the Rotary
Selector to the "OFF" position. The unit requires (2)
"AA" batteries to operate in PulseDose mode (Figure

1). The batteries will not become discharged as a
result of not turning the Rotary Selector to the "OFF"
position.

1

Press Latch to
Open Battery Door

The PD1000 mounts on a standard CGA870 type post

using guide pins and the knob (Figure 2). It can be
used on C, D, E, ML-6, M4 and M-6 size tanks at

pressures between 500-2250 PSIG. Also verify that the
regulator seal (Part #9286-RD) is in place and in good
condition (Section VI, A). Position the guide pins into

the tank post holes, and tighten the knob until the

PD1000 is securely in position and there are no seal

leaks.

The tank valve can now be slowly opened and the
rotary selector can be set to the prescribed ow rate.

Verify that a pulse is being delivered at the leading

edge of each inhalation. As the ow rate is increased,

so is the duration of the pulse (Figure 3).

To use the PD1000 in the "Continuous Flow" mode,
turn the Rotary Selector to the "CF" position (Figure 3).
See Note in the Important Parts section of the
instruction guide A-1000.

The "CF" ow rate is set at 2 liters per minute. This
ow rate can be changed by changing cannula ttings

(Figure 4). See Service Instructions Section VI, D.

Cannula Fitting

B. Operation

When using the PD1000 in the PulseDose mode, the
patient must breathe through the nose only. A standard
nasal cannula must be used. Do not use a pediatric or

low-ow cannula. The cannula with tubing can be up to

35 feet in length, but a 10 foot maximum is
recommended to lessen the chances of the oxygen
cylinder tipping over while in use.

Do not use on patients who can only mouth breathe.
The PD1000 should only be used on patients capable
of nose breathing.

LT-1859

INSTALLATION & OPERATION / MAINTENANCE PROCEDURES

Remaining battery life can be observed as the Pulse
Indicator Lights illuminate with each breath (Figure 5).

5

Battery
Indicator
Lights

If the Green Pulse Indicator Light illuminates with each

breath, the batteries have sufcient power (8 or more

hours).

If the Red Pulse Indicator Light illuminates with each
breath, the batteries have between 4-8 hours of battery
life remaining.

If the Red Indicator Light illuminates continuously, the
batteries must be changed. The unit can be used on

the continuous ow "CF" setting if no batteries are

immediately available.

NOTE-Turn the Rotary Selector to the OFF setting
prior to changing batteries.

NOTE-The oxygen cylinder will not last as long in

continuous ow mode as it would in PulseDose mode.

The contents gauge indicates the approximate amount

of oxygen left in the tank. It reads 1/4, 1/2, 3/4, and
full. It also has a red area to emphasize when the tank

needs to be changed (Figure 6).

IV. MAINTENANCE PROCEDURES

A. Testing

NOTE-The following should be performed after repair

or between patients

1. Install known good batteries.

2. Connect the unit to a pressurized oxygen cylinder
as described in Section III-A and connect a nasal
cannula.

3. Open the tank valve and verify that the PD1000
contents gauge indicates that there is a full tank.

4. Verify that there are no leaks around the tank seal
between the PD1000 and the oxygen tank.

5. Select any ow rate and simulate an inhalation

through the nasal cannula while verifying that a
"pulse" or bolus of oxygen is delivered with each
simulated breath.

6. Position the Rotary Selector to the "CF" position
and verify that the Continuous Flow Mode of
operation is functioning.

7. Verify that the top and bottom covers are not

cracked or broken.

8. Verify that the label can be read and is not
damaged.

9. Turn the Rotary Selector to the "OFF" position,

dose the tank valve, and remove PD1000 from

cylinder.

B. Cleaning

Wipe with a damp cloth having a maximum 5.25%
Sodium Hypochlorite (Bleach) or 3% Hydrogen

peroxide solution. Avoid getting uids or debris such as

sand or dirt inside the oxygen connections. Do not
immerse in water.

pulse with each inhalation
while properly connected to a
pressurized cylinder with the
post valve open.

Type II-

The regulator is leaking or the
gauge is broken or not reading

accurately.

Type III-

The cannula fitting is broken.

Type IV-

There is leakage between the
tank and the PD1000.

Type V-

Broken, damaged, or

non-functioning rotary selector.

1. Verify that the batteries are good and of specified type.

2. lf batteries are good, verify proper cannula connection and that patient is nose
breathing.

3. If yes, remove top and bottom covers (Section VI, C). Use a digital volt meter

and check the resistance across the Vacuum Switch (figure 7) with Rotary

Selector "OFF" when breath is simulated.

4. Refer to Section VI, E. If the resistance doesn't go to "0" when breath is simu­lated, change the vacuum switch.

5. If the resistance goes to "0" check the solenoid voltage (3VDC) when breath is

simulated and set to 6 LPM. (Refer to Figure 8)

6. If no voltage is present, change the PC Board.

7. If voltage is present, change the solenoid.

Refer to Section VI, C to remove the Regulator/Gauge Assembly and replace the
gauge or regulator.

Refer to Section VI, D to change the cannula fitting.

Close the tank valve, loosen the knob and verify that the post, the PD1000 regu­lator yoke and the tank surfaces are smooth and free of burrs. If they are smooth,

replace the regulator seal (#9286-RD). Refer to section VI, A.

D. Cannula Fitting Removal/Replacement

First remove the front and back covers.

NOTE-When removing or installing the cannula tting,
orient the manifold so the tting faces down to prevent
any debris from falling into the manifold which could
obstruct the continuous ow orice.

Use a 5/16" open end wrench and remove the cannula

tting by turning it counter-clockwise (Figure 12).
Replace with a new cannula tting and torque to 10

inch-lbs.

E. Solenoid/Vacuum Switch Testing and

Removal

Connect a piece of tubing to the cannula tting so that

a negative pressure can be created. Using a digital

voltmeter, check the resistance across the vacuum

switch as a negative pressure is created (Figure 7). If
the resistance doesn't go to "0" when a breath is
drawn, replace the vacuum switch.

If it goes to "0" but the solenoid doesn't open, check

the solenoid voltage (3VDC) (Figure 8). If there is no
voltage, change the PC Board. If there is voltage,
replace the solenoid (Figure 14).

To replace the vacuum switch, pull it apart from the
manifold/solenoid and the PC Board terminals (Figure

14). The vacuum switch can then be replaced by
pushing the manifold, vacuum switch, and PC Board
together. No tools are required.
