Ensure that the exhalation block is completely dried after cleaning and prior to use.
Warning
When an exhalation block is set up, each time it is removed, or after installing a new exhalation
block on the machine, it is essential that the exhalation flow sensor be recalibrated before the
exhalation block is used.
The exhalation block requires calibration and should only be removed or cleaned by qualified personnel.

4.8.1 Administering Oxygen
Warning
The ventilator must not be used with flammable anesthetic substances.
Oxygen therapy for patients with respiratory failure is a common and effective medical
prescription. However, be aware that inappropriate oxygen use may potentially lead to serious
complications, including, but not limited to, patient injury.
To avoid injury to the patient and/or possible damage to the ventilator: before using the
ventilator, use a flow meter (flow regulator) to regulate the oxygen supply to specifications
before connecting the ventilator to the oxygen supply.
Ensure that the oxygen supply pressure to the machine never exceeds 7 psi (50 kPa) or a flow of
15 lpm. Refer to
