Verify the functionality of the main alarms before connecting the patient to the ventilator.

Before starting ventilation, ensure that the device is properly assembled and that the air inlet, cooling
vents, and alarm sound diffusion holes are not obstructed. Ensure also that the patient circuit is of the
proper configuration (double or single limb), is properly connected to the ventilator, and that the circuit
hoses are neither damaged nor compressed and contain no obstructions or foreign bodies.
