Breathe normally, the
conserving device will deliver
a bolus of oxygen at the
leading edge of inspiration on
every breath up to 40 breaths
per minute.
WARNING
To prevent injury from cylinders tipping over, do not use cannula tubing lengths over 10 feet with small
compressed oxygen cylinders. Unattended cylinders should be secured in a cylinder stand.
NOTES
•
When this rotary selector is set to "OFF," the unit is not using battery power and will not pulse. When the
selector is set to one of the numbers, the unit is on and awaiting inspiration through the nasal cannula at
which time it will dose on every breath. The volume of the oxygen delivered varies according to which
prescription flow setting is chosen. The final setting on the rotary switch is "CF"; this is the continuous
flow position. In this position oxygen will flow from the cannula fitting at the default continuous flow rate.
•
Continuous flow mode is not powered by the batteries and can be used regardless of the battery level.
In the event of a device failure or dead batteries, the user must manually switch the unit to continuous
flow for delivery of oxygen. The device will not automatically switch to continuous flow. The oxygen
cylinder will not last as long in continuous flow mode as it would in PulseDose mode. Unless there is a
problem with the unit, such as dead batteries, the unit should be used in PulseDose mode.
•
When operated within the specified Operating Temperature Range, there is no "warm up" period
required. Should the device be outside the specified Operating Temperature Range, allow the unit to
stabilize within the Operating Temperature Range prior to use.
•
A mask should not be used in the PulseDose delivery mode as it may not fit to the face well enough to
allow the conserving device to sense inhalation efforts. Also, the therapeutic effect of PulseDose would
not be realized, as the dose of oxygen would be diluted in the mask prior to inhalation.
•
A pediatric or low-flow cannula should not be used in PulseDose delivery mode. The reduced diameter
of the cannula causes too much back pressure and will affect the oxygen volume delivered.
•
PulseDose delivers oxygen in a very short "puff." It does not deliver oxygen during the entire inhalation.
The length of time that PulseDose delivers oxygen will not vary from breath to breath. The time is set in
correlation to the oxygen dosage set on the conserving device (patient's prescription setting).
•
PulseDose is designed to prevent the delivery of pulses more than every 1 1/2 seconds. If the breath
rate is greater than 40 BPM, this feature prevents delivery of excessive oxygen by not dosing on every
breath.
•
If using NiMH batteries, carefully monitor when the low battery indicator flashes red. It is recommended
that a spare fully-charged set of alkaline batteries be kept in reserve and installed when the change
battery indicator is constant red.

When you are finished using
oxygen, turn the rotary
selector to the "OFF" position.
Close the cylinder.
