RULE OF 5S (KEEP IT SIMPLE VENT SETTINGS FOR ADULTS)
There are five numbered dials on the front of the Eagle/Impact Vent. Most settings can be set by remembering multiples of five. Do not hook up casualty to the breathing circuit until after the PEEP is set.
IMPACT 754 VENTILATOR PRE-MISSION CHECKS AND TROUBLESHOOTING
Routine Care
Duty Inspection
1. Power Off Checks:
a. Verify inspection is within the calibration date (6-month maintenance cycle).
b. Check the air inlet is clear of obstructions and the filter is in place (Right side of vent).
c. Verify the Gas (“OXYGEN IN” and “AIR IN”) and Patient (“EXHALATION VALVE” and “TRANSDUCER”) connections are clear and tight (Top of ventilator).
d. Verify the “GAS OUT” clear leaf valve is installed and seated (reseat if loose, replace if missing).
e. Inspect green high pressure oxygen hose for cracks, dry rot, threads, black O-ring (replace if damaged).
f. Connect the ventilator to a high pressure oxygen source, turn on the oxygen tank and ensure no leaks are present.
g. Turn off O2 when complete (conduct in environment conducive to hearing leaks).
2. Power On Checks
a. Turn “MODE” (knob 1) to desired setting (AC, SIMV, CPAP). The ventilator will run a SELF-TEST upon set up (ventilator circuit should be disconnected). At this point, (CAL) is not required. If SELF-TEST results in a Calibration Failure, place (1) to CAL until CAL OK is displayed. If the calibration fails, the ventilator must be taken out of service.
b. Check BATT OK
c. Preset ventilator knobs to:
3. Turn OFF.
4.. Make sure the air inlet and gas out ports of the ventilator are protected and covered.
EMERGENCY PROCEDURES
These procedures should be practiced before being performed on live patients.
NOTE: Any known malfunction of the ventilator should be addressed prior to utilization. The following are not for routine use, but for emergencies when alternate ventilatory measures are not available and long term BVM is not practical.
*ALL CAUTIONS, WARNINGS, AND NOTIFICATIONS THAT CORRESPOND WITH THE 754 SCREEN WILL BE IN ALL CAPS*
NOTE: First place the patient on BVM with supplemental oxygen. Second, check oxygen tank volume. Third, check the oxygen lines and connections.
Alternative Methods to Increase Delivered Oxygen Content
1. Oxygen reservoir kit for low pressure supply (Part # 820-0097-15).
2. Oxygen reservoir fashioned from primary circuit and BVM.
a. Connect short portion of main circuit tube to the BVM and to the air-inlet port.
b. Connect BVM oxygen hose to the BVM and regulator.
c. Set regulator to desired setting (~10LPM, but no lower than total minute volume).
3. Oxygen reservoir fashioned from second ventilator patient circuit.
a. Cut/disconnect exhalation valve off of second ventilator circuit.
b. Feed green transducer hose at least ¾ of the way down vent tubing (the goal is to get as close as possible to the air inlet port) and secure in place with tape (do not cover the end of the circuit).
c. Connect the 90 degree/”L” shape fitting of the green transducer line to the oxygen regulator.
d. Connect the opposite end of the vent tubing to the air inlet port.
e. Set regulator on oxygen source to 10 LPM to deliver up to 99% FIO2.
Missing or Damaged “Gas Out” Leaf Valve
Missing Gas Out leaf valve will trigger an alarm, give a DISCONNECT-CHECK CIRCUIT CONNECTIONS, no PEAK value will display, and little to no volume will be delivered to the patient.
WARNING: Occluding “Gas Out” side ports will enable the ventilator to provide full respirations, however, this will eliminate the anti-asphyxia function these ports provide. (Ventilator failure will result in increased resistance in spontaneous respiration) and strict surveillance must be kept on ventilator to ensure any further failure is caught immediately. Patients must immediately be transitioned to BVM in the event of any failure.
Compressor Failure/Alarms (may show CODE 2).
NOTE: This technique will transition the ventilator to using oxygen pressure instead of the compressor to gather drive ventilation and may hasten oxygen usage.
