is the continuous flow position. In this position oxygen will flow from the cannula fitting at the default
continuous flow rate.

NiMH batteries for use and recharge instructions.

Alerts
No Inspiration Alert–If the unit is on and inspiration has not been sensed for 15 seconds, the audible and
visable alert will pulse until an inhalation is sensed or the selector is turned off.
NOTE–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.

INTRODUCTION

How PulseDose Works
PulseDose dramatically extends the use time from a supply of oxygen, offering increased mobility with
improved comfort and increased efficiency. The reliability and safety of PulseDose oxygen delivery has been
proven effective in clinical testing as well as through independent tests performed by physicians and
respiratory therapists.
What is PulseDose? The concept is based on the fact that the normal breathing pattern is inhalation for 1/3 of
the time, and exhalation about 2/3 of the time. At 20 BPM the oxygen delivered in continuous flow, assuming
inspiration is 1/3 of the breathing cycle, would be 16.5 cc/LPM. As a result, PulseDose extends the use time of
an oxygen system by an average of 3:1. PulseDose senses the start of inhalation and instantly releases a
short "pulsed" dose at the very beginning of the breathing cycle. Since all of the "pulsed" oxygen finds its way
deep into the lungs, less oxygen is required to accomplish the same effect than with traditional continuous flow
oxygen systems. This means that a PulseDose oxygen system will last two to four times longer than a
continuous flow oxygen system, yet still provide the same therapeutic benefit.
Because oxygen is released only during inhalation, the constant flow of oxygen into the nostrils is eliminated.
Many users find PulseDose oxygen delivery more comfortable than continuous flow delivery systems. The
short "pulse" of oxygen delivered during inhalation is almost undetectable, and the humidity in the room air
helps maintain a normal level of moisture in the nasal cavity. This greatly reduces the discomfort of
dehydration associated with a continuous flow oxygen system.
Because PulseDose responds to each individual's breathing patterns, the use time will vary for each individual
depending on the PulseDose prescription rate and the breath rate. The following chart shows the theoretical
ambulatory ranges for DeVilbiss PulseDose products.
NOTE–All ambulatory ranges are calculated assuming a breath rate of 20 breaths per minute in PulseDose
(PD) mode.
