11. Warning: Provision of Alternative Means of Ventilation (Section 4)
In accordance with recognised industry practice for all ventilators ensure that, whenever a
patient is being ventilated by means of an automatic ventilator, an alternative means of
ventilation (e.g. a manual ventilator) is readily available to use should ventilator failure occur.
12. Warning: Adequacy of Gas Supply (Section 4(b)(ii))
To ensure that ventilation can be maintained without interruption keep a constant check on
the adequacy of gas supply by observing the gas cylinder contents indicator and the gas
failure visual alarm.
13. Warning: Care When Using Ventilator for Manual Ventilation (Section 4(d))
The operator must maintain constant observation of the patient pressure manometer during
manual ventilation using the ventilator to ensure that over-inflation is avoided.
14. Warning: MRI Use (Section 4(h))
The normal routine of checking the ventilator system for magnetic attraction should be
followed whenever the equipment is taken into an MR environment. It is also recommended
that every time a patient is positioned in the magnetic field the manometer is checked to
confirm unchanged ventilation and the high pressure relief/alarm system is checked by a
temporary circuit disconnection and occlusion of the ventilator outlet connector. These
procedures are the minimum required in safeguarding against projectile risks or altered
performance due to the inadvertent addition of magnetically attracted parts or changed
compatibility conditions.
15. Warning: Use in Extreme Environments (Appendix B)
Although use of this ventilator outside the environmental conditions specified in this manual
will not directly lead to a safety hazard, the performance will become increasingly uncertain
as the conditions become more extreme. Therefore the operator must exercise particular
patient vigilance under these conditions.
16. Warning: Oxygen Concentration (Section 2(c))
An important safety feature of the babyPAC is that it continues to operate after the failure of one
of the supply gases during two gas operation. If both oxygen and air are connected as gas sources
then the 21% to 75% concentration (yellow scale) becomes operative. If the compressed air
supply is turned off the unit automatically reverts to the 50% to 100% concentration scale (white
scale). However an inevitable change of delivered oxygen concentration occurs as indicated by
the dual scale calibration. Therefore in the event of medical air supply failure the oxygen
concentration should be reset if clinically necessary.
If the oxygen supply ceases for any reason, the ventilator will only supply 21% oxygen to the
patient, irrespective of the oxygen control setting. The control should always be left at the 21%
setting in this mode of operation in order to achieve maximum gas economy.
