General information
Puritan Bennett™ 700 Series Ventilator System Service Manual 10070389 Rev. A 1-29
SPONT MINUTE
VOLUME (L)
(760 only) Shows the patient’s measured expiratory
minute volume for all spontaneous breaths,
based on the previous 60 seconds or
8 breaths (whichever interval is shorter).
Updated at the beginning of each breath.
The calculation is reset when ventilation
starts, when apnea ventilation starts or
autoresets, when you change the mode or
breath type, and when you press the alarm
reset key. 0 to 99 L
Accuracy:
±
(10 ml + 10% of reading)
Alarm settings
HIGH RATE An active alarm indicates that measured
respiratory rate is higher than the alarm
setting. 3 to 100 /minute
Accuracy:
±
(0.1 +1% of setting)/minute
HIGH TIDAL
VOLUME An active alarm Indicates that exhaled
volume for three out of four consecutive
breaths was above the alarm setting. 20 to 6000 ml
Accuracy:
±
(10 ml + 10% of setting)
LOW INSP
PRESSURE An active alarm indicates that monitored
circuit pressure is below the alarm setting at
the end of inspiration. Inactive in SPONT
mode unless the speaking valve option is
enabled. 3 to 60 cmH
2
O (3 to 60 hPa)
Accuracy:
±
(1 + 3% of setting)
LOW TIDAL
VOLUME An active alarm indicates that exhaled
volume for three out of four consecutive
breaths were below the alarm setting. (If this
alarm is set to 0 ml and breath type is PCV or
PSV, an active alarm indicates that delivered
volume is less than 3 ml for three out of four
consecutive breaths.) 0 to 2000 ml
Accuracy:
±
(10 ml + 10% of setting)
HIGH PRESSURE An active alarm indicates that two
consecutive breaths were truncated because
circuit pressure reached the alarm setting. 10 to 90 cmH
2
O (10 to 90 hPa)
Accuracy:
±
(1 + 3% of setting)
LOW MINUTE
VOLUME An active alarm indicates that monitored
minute volume is less than the alarm setting,
based on an eight-breath running average or
the previous minute, whichever is less. 0 to 50 L
Accuracy:
±
(10 ml + 10% of setting)
Other indicators
