Setting Up the Ventilator

preparing the UaM and the Ventilator

1. Ensure that equipment such as the ventilator and the patient monitor are
securely attached to the top shelf of the UAM

2. Ensure that all cables and sample lines are correctly attached – refer to the
manual of each individual manufacturer.

3. Connect these essential items:

a. Patient Circuit with Y piece.
b. Ventilator to UAM using the ventilator drive hose.
c. Ventilator patient flow sensor between the patient Y piece and the

bacteria filter.
d. Ventilator patient flow sensor sample lines at rear of ventilator
e. Patient bacterial filter to prevent flow sensor contamination
f. Theatre anaesthetic gas scavenging system

Ventilator ConneCtionS

1. Flow sensor connection – The patient inspired and expired

gas is measured with a variable orifice flow sensor.
a. Distal to patient – The clear tube is connected furthest from the patient.
b. Proximal to patient – blue tube. The blue tube is connected closest to

the patient.

note: A breathing circuit filter must be used to prevent contamination.

2. Bellows connection – 17 mm male taper that is attached to the UAM

anaesthesia machine using a 15 mm x 1.5 m black corrugated breathing hose.

3. Mains power inlet socket-IEC power cable.

perforMing the pre-USe CheCkS

1. Check the ventilator for labeling to indicate if the machine has any faults or

needs to be serviced

2. Check for visible signs of damage.

3. Check the correct connection of the patient circuit and any auxiliary

equipment such as patient monitoring equipment, gas scavenger etc.

4. Perform a patient circuit leak check:
a. With the patient circuit connected check that all connections are secure

and all tubes used are in good condition.

b. With the UAM anaesthesia machine in manual bellows mode block

the patient Y piece and ensure that the manual bellows on the UAM
anaesthesia machine can generate 30 cmH2O or more pressure when the
bellows is pushed down without the bellows descending due to a leak.

iSolating the hand BellowS

Push the lever to the rear to isolate the
hand bellows and pull it forward when
the hand bellows is in use.

The Manual Bellows Isolator lever isolates
the Hand bellows from the breathing
circuit when the ventilator is being used.

On/O push button for 1 second.

Start Up Self teSt

If the patient circuit was connected
to a patient or a test lung, the ventilator
will alert you to remove the Y piece and
press to repeat tests.

When the ventilator turns on it will
perform a series of self-tests and the
bellows will move up and down. The
screen will be blank at this time.

note: During these tests, the breathing circuit must be disconnected from
the patient.

patient SeleCt SCreen

Once the self-tests are over the patient
select screen will appear.

The patient select screen allows the user to
choose patient ventilator settings by weight
– 3kg, 10kg, 25kg, 50kg, 70kg and 100kg or
by selecting one of 6 user-defined settings.

Connect, pulse oximeter probe, NIBP cu
and ECG leads for patient monitoring.

Patient select screen with body weight
setting for 50Kg selected. Note that the
selected key is now black and that the
ventilator settings for this weight are
displayed on the left hand side

Starting the Ventilator

Observe that no alarms are indicated in the
alarms dialogue box – this indicates that
there are no system errors, including mains
power, battery failures. The alarms are
disabled until the ventilator is switched to
the “start” screen allowing the ventilator to
be turned on without nuisance alarms.

Once the user has chosen the initial settings
the actual settings can be adjusted as
required prior to starting to ventilate. If
the settings are to the users satisfaction,
pressing the green “Start Case” button
shown on the lower left hand side of the
display will start the ventilator.

Patient settings are displayed in the “SET”
column on the right hand side vertical
column. These settings can be adjusted
before or during a case. All functions
require “OK” to be pressed to confirm the
setting change. If the setting change is
made and the OK button is not pressed
the screen will time out and stay at the
original setting.
