-If the patient is spontaneously breathing between the set mandatory rate, Pressure Support (Pps) can
be added. The patients spontaneous VT between the set rate can be adjusted by increasing or
decreasing the amount of PS. For larger
VT increase the PS and for less VT decrease the amount of
PS.
-When a patient triggers a spontaneous breath either with PS or the trigger turned on, a vertical line
will be noted at the on the Pressure and Flow waveform at the start of inspiration to indicate the breath
was trigger by the patient and was not the routine mandatory breath.
Pressure Support Ventilation (PS) –Depress the “Press. Supp.” Soft key. The default key parameters
for Pressure Support ventilation appear. To change a setting, simply depress the soft key below that
parameter, turn the rotary knob and confirm. Once the desired settings are present, confirm the rotary
knob once more to activate the ventilator. Indications for use of Pressure Support are a spontaneous
breathing patient that needs their own VT augmented to ensure adequate ventilation. The amount of PS
set will determine the VT delivery. By increasing the amount of PS set will increase the VT and
decreasing the amount will decrease the VT
-The set respiratory rate on PS ventilation is a back-up rate for apnea ventilation. The set rate functions
as time cycled ventilation. For example, if the rate is set at “4” the ventilator will need to see a
spontaneous breath every 15 seconds. If a spontaneous breath does not occur, a mandatory breath will
be delivered at the set PS and will continue at the set rate of 4 breaths every minute until the patient
performs a spontaneous effort. When the patient resumes breathing, the mandatory breaths cease and
allows the patient to initiate the spontaneous pressure supported respirations.
Most common alarms- (For a complete list of troubleshooting, refer to Chapter 12 of the Operator’s
Manual)
“FG LOW OR LEAK” – more flow is needed or a leak has occurred in patient circuit.
“VT NOT ACHIEVED” – The set volume was not delivered. Check for leak, correct any pressure
limiting of inspiration time or check the fresh gas supply setting.
“PINSP NOT ACHIEVED” Check the ventilation parameters, more fresh needed or possible leak.
“PRESSURE LIMITING” - This message occurs if the patients peak pressure reaches the P-MAX set
in Volume Control. You either have to increase the P-MAX, decrease the set VT or try “Pressure
Control.” Also check tube, hoses and filter for occlusion.
The three categories of alarms based on priority and identified by color.
Warning - message with high priory (red)
Cautions - message with medium priority (yellow)
Advisory - message with low priority (white)
End of Day
Turn machine off at the end of day – Power switch on front of machine. Assure all flow meters are off.
Soda Lime – The Apollo scrubs CO2 from the bottom-up. If the granules are depleted by ¾, replace.
Vaporizers – Check site glass for fill level. Fill as needed.
*Please remember* When filling the Sevo and Iso Vaps, the lever does not need to be flush!
