Care & Maintenance - DeVilbiss PulseDose PD1000I Instruction Manual

Remember to check the oxygen contents gauge periodically to verify that there is an adequate oxygen
supply. If the oxygen supply runs out, the green PulseDose indicator light will continue to illuminate,
indicating that the conserving device is being triggered by inhalation.
Q. Why can't I use a cannula which is longer than 35 feet?
A. The PulseDose triggering is not significantly affected by the cannula length, but the delivery of oxygen is
affected. If the cannula is longer than 35 feet, the pulse of oxygen is delayed. Remember the therapeutic
moment during the inhalation cycle. If the oxygen is not delivered during this time, the benefits will not be
realized.
Q. I've always used humidifiers with oxygen. Should I use a humidifier with PulseDose?
A. No. PulseDose is not able to sense inhalation through the water in the humidifier. Also, many patients find
that humidification is not necessary with PulseDose. They find that PulseDose improves comfort because
it delivers a very small amount of oxygen during the early part of inhalation, while the rest of the inhalation
is composed of normal room air.
Q. When I'm breathing faster, I don't get a pulse with each breath. Don't I need a dose every time?
A. Because PulseDose breathes with the patient, it has an upper limit (40 Breaths Per Minute) that keeps
you from getting too much oxygen. When breathing slowly, you receive a dose with every breath. As
breath rate increases (up to 40 BPM) PulseDose still delivers a dose with every breath. At this point, you
are getting more oxygen per minute because each pulse delivers the same amount of oxygen with each
breath while the number of breaths has increased. With continuous flow oxygen, the oxygen delivered is
constant. As you breathe faster, the enrichment of inhalations actually decreases because each breath is
being diluted with a greater amount of room air.
Q. Why is my conserving device beeping every three seconds?
A. The PulseDose conserving device will beep if breathing is not sensed while the device is on. This could
be affected by the cannula position or mouth breathing/shallow breathing.
USER CARE AND MAINTENANCE
The unit should be kept clean and free from moisture and dust. Clean the unit at least weekly by wiping with a
dry, lint-free cloth. Avoid getting fluids or debris such as sand or dirt inside the oxygen connections. Do not
immerse in water. Do not clean with a solvent based cleaning solution. Avoid dropping the unit or placing it in a
position where it could topple or fall since this can damage the device. Whenever possible, use a padded
carrying bag such as those listed in the Accessories section to carry the unit. This will help to protect it in case
of a fall. The unit should be protected from extreme temperatures. Do not attempt any other maintenance.
STORAGE & HANDLING WARNINGS
When attached to a cylinder, do not place oxygen cylinders in unventilated spaces such as car trunks.
Excessive heat can make the relief valve suddenly and quickly discharge the cylinder contents,
possibly making it a projectile and greatly increasing the oxygen level in unventilated spaces.
Do not leave oxygen cylinders in the cabs of vehicles without ventilation. If a cylinder leaks, a spark
could start a fire causing serious injury or death.
Remove cylinders from the vehicle when the destination is reached. Be sure to secure cylinders from
movement during transport.
Heat, Humidity, Sun and Artificial Light have no effect on operation as long as the device is used
within the product specifications.
This device contains electrical and/or electronic equipment. Follow local governing ordinances and
recycling plans regarding disposal of device components.
