Q. How Does A Conserving Device Work? How Does It Know When I'm Inhaling?
A. W hen inhaling, your diaphragm moves down and causes a drop in pressure in the lungs. Air flows in through the nose and mouth to
equalize the pressure. This negative pressure is also present at the nose and mouth during inhalation. This pressure signal travels through
the nasal cannula to a pressure sensor in the conserving device. A mechanical or electronic circuit then opens a valve to deliver a
precisely metered dose of oxygen. When the valve is closed, the sensor is ready to detect the next inhalation.
Q. The Pulse(s) Seem So Short. Am I Really Getting Enough Oxygen?
A. Y es. PulseDose delivers a precise amount of oxygen at a relatively high flow rate during each inhalation. This assures that the oxygen
delivered flows deep into the lungs for maximum benefit. PulseDose requires less oxygen to deliver the same therapeutic benefit as
continuous flow oxygen delivery.
Q. I Can't Hear The Pulse. Is PulseDose Working?
A. I f the pulse can't be heard, simply look at the green PulseDose indicator to see that the device is being triggered by inhalation. For
further assurance, hold the end of the cannula in front of your lips while inhaling through your mouth and feel the pulse. PulseDose does
not monitor the supply of oxygen. 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 With PulseDose?
A. T he 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. N o. PulseDose is not able to sense inhalation through the water in the humidifier. Also, many patients find that humidification is not
necessary; they find that PulseDose improves comfort because it delivers oxygen by pulse while the rest of the inhalation is composed of
normal room air.
Q. W hen I'm Breathing Faster, I Don't Get A Pulse With Each Breath. Don't I Need A Dose Every Time?
A. B ecause 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, the devices still deliver 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.
CaRe & MaInTenanCe
The DeVilbiss iFill Oxygen Cylinders should be kept clean and free from moisture and dust. The cylinders should be protected from extreme
temperatures. Clean the cylinders periodically by wiping with a dry, lint-free cloth. Do not clean with a solvent based cleaning solution. Avoid
dropping the cylinder 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 the Hideaway or Walkabout bags to carry the cylinder. This will help to protect it in case of a fall. Avoid getting fluids or debris
such as sand or dirt inside the oxygen cylinder and/or oxygen connector. Do not immerse in water. Do not attempt any other maintenance.
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.
