F7 and F8 are bacteria filters. They are connected to the inspiration port and patient port
when they are used by the ventilator. The nebulizer is pneumatic. The drive gas is introduced
into the nebulizer via the nebulizer connector on the front panel; and the liquid medicine is
nebulized, enters the inspiratory tube, and reaches the patient’s lungs. The pneumatic
nebulizer can be connected only when the machine is connected with high-pressure O2.
