The patient should pay attention to the following points when using the ventilator for the first time :
a. When using the ventilator for the first time, first turn it on and off once to determine whether the switch can be properly controlled and check whether the machine is working properly. If you have any questions, please contact the seller or manufacturer in time.
b. Read the product manual carefully before use, and connect the ventilator, humidifier, nasal mask or mouth-nose mask according to the instructions in the manual.
c. Wear the nasal mask or mouth-nose mask and adjust the headband tightness. The elasticity of the headband is generally suitable if the mask does not have a pressure on the patient’s corresponding parts, but it should not be too loose to avoid air leakage.
d. Make sure that the humidifier has been added with purified water or distilled water, and can not exceed the specified position.
e. Start the ventilator and feel if there is any abnormality in the operation of the ventilator. If there is no abnormality, you can use it with confidence.
f. If the patient wants to temporarily leave the machine during use, it is best to turn off the machine, take off the nasal mask or mouth and nose mask, and then leave. After returning, wear the nasal mask or mouth and nose mask before restarting.
g. After using every day, be sure to turn off the machine and then cut off the power.
h. It is best to clean the mask once a day, and filter sheets and pipes every three days. The cleaning method can refer to the disinfection method of ventilator accessories.
i. Change the water in the humidifier every day, preferably not exceeding the water level line.
j. The machine should be maintained every six months or a year. You can contact the sales company or manufacturer when maintenance is required.
