Pulse Dose Mode Specifications
Pulse Settings
1.0 to 6.0, in 8mL increments up to 96 mL; 7-9 in 32mL increments up to 192 mL
Trigger Sensitivity
Adjustable between settings of 1 (most sensitive) to 3 (least sensitive)
Adjustable Bolus Rise Time
Adjustable settings of Fast(factory setting), Medium, or Slow
Trigger Criteria
• Cannula pressure has dropped below the trigger point (typically between
0.135—0.37 cm of H
2
O of negative pressure)
• At least 1¼ seconds has passed since the last pulse began
Minimum time between breaths 1.25 seconds (max. 3 consecutive breaths)
Response to Missing Breaths
While in Pulse Dose Mode, the eQuinox is always monitoring for breath detection.
After 15 seconds of no breath detected, the eQuinox “delivers” Continuous Flow at the
last Continuous Flow setting. After another 15 seconds, the eQuinox stops delivering
Continuous Flow and waits 15 seconds for a breath. The eQuinox will stay in this modality
until a breath is detected.
