SBT TIME
The SBT TIME message is displayed during the Spontaneous Breathing Trial mode of ventilation
when only two (2) minutes of SBT mode of ventilation remain.
This is an informational message only.
When a SBT TIME message is generated:
• The SBT TIME message is flashed in the display window.
• The audible alarm is sounded.
To reset the SBT TIME message:
1) Push the Silence Reset button once to silence the audible alarm.
2) Push the Silence Reset button twice to reset the alarm status message (silences the audible
alarm and clears the flashing display).
WARMUP xx
When the ventilator is first powered up, the transducers require up to 60 seconds of warm-up time
before they will operate within their normal tolerances. During this warm-up period, the ventilator will
not allow you to run the leak test or calibration. If you select an option that is not available during the
warm-up period, the WARMUP xx message is displayed. When the warm-up period has expired, the
message is removed.
When a WARMUP message occurs:
• The WARMUP message and the remaining warm-up time are displayed in the window.
• The ventilator does not allow the restricted functions to be performed.
To reset the WARMUP message:
1) The WARMUP message will automatically reset when the warm-up period has expired.
