Model 1000 User Manual
Pulse Flow Mode is designed to deliver 16 ml boluses of oxygen
per incremental flow setting for each patient inspiration detected.
Bolus volume is held constant regardless of breath rate within
a given setting. Delivery of the bolus is triggered by detection
of the end of inspiration followed by the start of a subsequent
inspiration. Sensitivity is dealer/provider adjustable. Based on
this inspiration trigger signal, a "pulse" of oxygen is released to
the patient by an electronically controlled flow valve. There is
no mixing of oxygen with room air.
Increments of 1– 6 times (x) the bolus of 16 ml
(16 to 96 ml per breath)
± 15%
6 to 25 breaths per minute average, sustainable
1.25 seconds (maximum 3 consecutive breaths)
ECLIPSE switches to Continuous Flow Mode after 30 seconds
without breath detection.
