5.10 Ventilatory Control Functions
With the correct supply gas (oxygen/air), note the following delivered parameters at the stated
control settings whilst ensuring no pressure limiting occurs: (Patient = 20C+20R, mode = adult
run & min fresh gas.) After changing any settings wait for compliance compensation to come
back on before taking any readings.
BPM TV(L) Ratio Delivered and Monitored Parameters to Note
6 1.0 1:1.0 Freq Ratio TV
6 1.0 1:Max Ratio
10 1.0 1:2.0 Ratio TV
20 0.6 1:3.0 Freq TV
20 0.4 1:Min Ratio
20 0.2 1:2.0 Ratio TV
40 0.2 1:2.0 Freq
60 0.2 1:1.0 Ratio TV
90 0.1 1:2.0 Freq Ratio TV
Max ratio for the 8500 is 1:5. Min ratio for the 8500 is inverse 2:1
5.11 Expired Volume and Alarms
Set ventilatory controls to: MV/TV = 10L/1000ml
Freq = 10 BPM
Ratio = 1:2.0
After one minute note the ventilator monitored MV and TV.
Reduce MV/TV to 4L/200ml and increase frequency to 20 BPM.
Press the Alarm menu button – choose Alarm Limits and set MV Low alarm at 2.
Open a small leak in the airway and verify the MV low alarm turns on immediately the
first MV reading occurs below 2.0 L (50% of set MV). Check active alarm stops 30 seconds
after MV reading is increased to
≥
2.0 L. (After the leak is closed off.)
Set frequency to 20 BPM.
Set MV low alarm to 4 and MV high alarm to 6
Increase the fresh gas supply until the ventilator monitored MV rises to >6.0 L (> 150% of set
MV) and verify the MV high alarm turns on immediately the first MV reading occurs
above 6.0 L. Check active alarm stops 30 seconds after MV reading is reduced to
≤
6.0 L.
Set the MV high alarm to 25.
