SBT > f
When the Spontaneous Breathing Trial (SBT) mode of ventilation is on and the Total Breath Rate ( f )
is greater than the SBT HIGH f setting (high limit of breath rate range) for 30 seconds, the SBT > f
alarm is generated.
For additional information concerning the Spontaneous Breathing Trial (SBT) mode of ventilation, see
SBT (Spontaneous Breathing Trial) Operations in Chapter 10 - Extended Features.
When a SBT > f alarm is generated:
The SBT > f message is flashed in the display window.
The audible alarm is sounded.
To reset the SBT > f alarm:
1) Push the Silence Reset button once to silence the audible alarm.
2) Push the Silence Reset button twice to reset the alarm (silences the audible alarm and clears
the flashing display).
When the SBT > f alarm is reset (Silence Reset button pushed twice), the alarm is
suspended for the next 60 seconds.
The 60-second suspension of the SBT > f alarm is only enabled when the alarm is manually
silenced/reset by pushing the Silence Reset button twice. It is not enabled when the SBT > f
alarm is automatically silenced/reset because the patient’s breath rate is no longer greater
than the set SBT HIGH f alarm value.
When an SBT alarm has been active in excess of 5 minutes, the SBT mode of ventilation is
terminated, the ventilator clears the alarm status, silences the audible alarm and returns to its
previous mode of ventilation / settings. To remove the flashing SBT alarm message from the
display window, push the Silence Reset button.
NOTE
The Spontaneous Breathing Trial feature is only available when Flow Sensing Patient Circuit mode is
enabled (see Chapter 12 – Operating Procedure for additional information).
REMARQUE
La fonction d’essai de respiration spontanée n'est disponible que lorsque le mode de circuit patient
de détection d'écoulement est activé (reportez-vous au chapitre 12 – Procédure d'utilisation pour
d'autre information).
