PULSE FLOW MODE FEATURES:
The SAROS Pulse Flow Mode delivers a high flow oxygen bolus at the beginning of each inspiration. Your SAROS Pulse Flow Mode has a
feature, called autoSAT Technology and a Pulse Flow Mode Sensitivity Setting to easily trigger the oxygen bolus delivery.
These features are provided to ensure that patients can easily trigger a delivery of an oxygen bolus and that the oxygen bolus maintains
consistency over higher breath rates.
autoSAT Technology provides a consistent bolus volume of oxygen as a patients' breath rate increases or decreases.
NOTE: Bolus volume decreases as breath rate exceeds published range.
The Pulse Flow Sensitivity (P SENS) can be adjusted in the Utility Menu from 1–3. A setting of 1 is the most sensitive and a setting of 3 is
the least.
WARNING: PULSE FLOW MODE SETTINGS MUST BE DETERMINED FOR EACH PATIENT INDIVIDUALLY. SETTINGS USED IN THE
CONTINUOUS FLOW MODE MAY NOT APPLY, OR BE APPROPRIATE, IN THE PULSE FLOW MODE AND VICE VERSA.
WARNING: AS WITH ALL OXYGEN-CONSERVING TYPE DEVICES, THE SAROS MAY NOT BE ABLE TO DETECT ALL INSPIRATORY
EFFORTS IN THE PULSE FLOW MODE.
