14. Basic Operating Instructions
This panel on the ventilator gives basic operating instructions to assist the infrequent user of
the babyPAC ventilator. These instructions are not intended to replace, in any way, the
more comprehensive instructions and information given in this Manual. A table is provided
to assist the user in calculating ventilatory frequency from the settings of T
I
and T
E
.
15.
Alarm Information Label
This label provides alarm battery information and a key to alarm signals.
16. Patient Pressure Manometer
This pressure measuring device displays the patient pressure during both the inspiratory and
the expiratory phase. This pressure is measured at the ventilator outlet to the patient circuit
but when using the patient circuit provided the measured pressure is within 2 x100Pa (2
cmH
2
O) of the pressure at the patient connection under all modes of use.
17. Gas Output Port
This 22/15mm conical outlet connector is where the inspiratory limb of the patient circuit is
connected. The patient inflation pressure is also monitored inside this port.
18. Gas
Return Port
This 22/15mm conical connector is where the expiratory limb of the patient circuit is
connected. It contains the exhalation valve that controls the breathing circuit pressure.
Exhaled gas vents to atmosphere at this connector. The connector can be removed for
cleaning by means of the knurled diameter, as described in section 5(b)(ii).
19.
Supply Gas Inlet Connection(s)
Two connectors are provided for the supply of pressurised oxygen and air respectively. As
standard, these are non interchangeable, proprietary, permanent connectors that require a
spanner for disconnecting or connecting the supply hoses. User connectable gas specific
connections in compliance with most major European, International and National Standards
can be fitted as alternatives if specified at the time of ordering. For correct ventilator
operation the gases supplied must be regulated and must be maintained within the pressure
range of 305-600 kPa (3.05 to 6 bar) when supplying up to 20 L/min flow.
The ventilator will operate with only one gas being supplied but, as explained previously, if
only air is supplied the delivered oxygen concentration will be 21% irrespective of the
setting of the concentration control.
20.
Gas Intake Port
This port is used to take fresh air into the gas mixing system during certain modes of
operation. It must, therefore, be kept free of obstruction at all times. It is fitted with a
sintered metal filter to remove particulate matter from the entrained air.
21. Patient
Circuit
The standard patient circuit consists of a symmetrical Y circuit with equal length and
interchangeable inspiratory and expiratory limbs
WARNING:
Circuits of alternative materials may be used but if these circuits have higher
compliance ventilatory performance may be compromised. Corrugated disposable
hoses are not recommended for this reason.
