14.3.3 Nebulization of Medication
When using a nebulizer kit with the patient circuit,
the nebulizer requires an additional flow of gas
which alters the prescribed set PIP and PEEP
levels.
Disconnect the tube with the temperature probe port
(A) from the tube (B).
Insert the nebulizer (C) into the circuit.
Connect the free end of the nebulizer supply tube
(D) to the base of the nebulizer.
Connect the nebulizer to a flow meter.
Operational Changes
When using the SLE4000/5000 with a nebulizer, the
ventilator should be used as time cycled pressure
limited device by removal of the flow sensor.
Removing the flow sensor from the ET manifold
whilst still connected to the ventilator is not advised
as the “Breath Not Detected” alarm will become
active and mask other alarm conditions that could
arise.
When nebulization of the fluid is complete the flow
sensor should be recalibrated and inserted back
into the circuit.
14.3.3.1 Nebulization Procedure
Step 1 Note the set PIP and PEEP.
Step 2 Disconnect the flow sensor cable from the
ventilator and press the “Continue without
flow sensor” button.
Step 3 Remove the flow sensor from the ET
manifold.
Step 4 Insert the nebulizer kit into the patient
circuit.
Step 5 Connect the nebulizer to a flow meter.
Step 6 Fill the nebulizer with the fluid to be
nebulized.
Step 7 Increase the high alarm threshold in the
pressure waveform window.
Step 8 Set a flow of gas through the nebulizer via
the flow meter of 6 to 10 l/min (dependant
on the rate required for nebulizing).
Step 9 Adjust the PIP and PEEP to compensate
for the increased flow of gas through the
ET manifold.
Step 10 After nebulization close off the flow meter.
Step 11 Connect the flow sensor and recalibrate.
Step 12 Remove the nebulizer kit and reconnect
the inspiratory tube to the ET manifold.
Step 13 Re-fit the flow sensor between the ET
manifold and the ET tube.
Step 14 Adjust the PIP and PEEP to compensate
for the decreased flow of gas through the
ET.
Warning: When nebulizing using flows of 6 to
10 l/min (dependant on the rate required for
nebulizing), this will cause the PEEP and PIP
pressures to rise and will require adjustment
of the PEEP and PIP pressures at
commencement and completion of
nebulizing.
