BPM Parameter Window Options
The BPM (Breathes Per Minute) parameter window defines the number of breaths per minute
delivered by the ventilator, as well as other parameters related to breath timing.
For AC and SIMV ventilation modes, the BPM parameter displays the setting as solid text. The
BPM parameter range is 0 to 80.
The BPM measured range is from 0 to 99.9
When CPAP and BL mode are used the primary parameter is the patient's breathing rate, shown
in the outlined text.
Assisted and controlled breaths are time-triggered and time-cycled. Spontaneous breathes are
patient triggered and flow cycled.
Secondary Parameters and Alarm Thresholds/Limits
The secondary parameters for the BPM parameter window are the following:
•
High BPM alarm limit (number immediately below the Alarm Bell symbol)
•
Low BPM alarm limit (lower number below the Alarm Bell symbol)
•
Control Parameter (I:E ratio or Ti)
Note:
Display of I:E or Ti in the BPM parameter window is determined by the Control
Parameter setting in the BPM context menu
The high breath rate alarm can be set off, or it can be set from 20 to 99.
The low breath rate alarm can be set from 2 to 40.
