WARNING: On child settings an increase in tidal volume may be experienced when
switching to Airmix due to the nature of entrainment valve.

are advised to use additional monitoring equipment.
4.3.5 Through patient observation ensure that the patient is still being correctly ventilated and
oxygenated.
4.3.6 When the Airmix function is no longer needed then return the Airmix control (Fig:5,z) to the
