What are the steps and advantages of non-invasive ventilator operation process?

So, what are the steps of the operation process of non-invasive ventilator? What are the advantages? Non-invasive ventilator is used for respiratory failure caused by various diseases, postoperative respiratory failure, neuromuscular diseases, aggravation of respiratory failure after assisted weaning or extubation, asthma, obesity hypopnea syndrome, restrictive ventilation dysfunction caused by chest diseases, sleep apnea syndrome, respiratory rehabilitation and so on. Advantages of non-invasive ventilator: 1, simple operation, avoiding tracheal intubation and tracheotomy. 2. Protect the airway defense function. Prevent the off-line difficulty caused by long-term ventilator support, reduce the hospitalization time of patients and reduce medical expenses. The operation flow of non-invasive ventilator is not difficult, and its steps are: 1, connecting oxygen flowmeter, oxygen inhalation pipeline and ventilator pipeline, adjusting oxygen flow and connecting ventilator power supply. 2. Install the ventilator: (1) Add sterilized distilled water to the humidifier, which shall not exceed the online level and not be lower than the offline level; (2) the humidifier is connected with the ventilator outlet, and the humidifier outlet is connected with the breathing tube; (3) that other end of the breathe tube is connected with an exhaust valve and a mask. The headband is fixed. 3. Parameter adjustment (1) mode: CPAP, BiPAP(PSV+PEEP). S，S/T； (2)IPAP and EPAP settings, standby breathing frequency; (3) set humidification and inhalation time and pressure delay; (4) Oxygen flow. 4. Post-evaluation of non-invasive ventilator: vital signs, SPO2, blood gas analysis and man-machine cooperation. 5. Adjust the ventilator parameters according to the evaluation, and pay attention to the tightness of the headband.
