1. The S mode of the ventilator (Spontaneous spontaneous breathing mode)

Also known as autonomous trigger mode or synchronous mode. It means that people trigger the ventilator to send air through their own breathing (the machine provides inspiratory pressure IPAP when inhaling, and the machine provides expiratory pressure EPAP when exhaling). The working frequency of the machine is completely controlled by the patient's own breathing. This mode is mainly suitable for in spontaneously breathing patients. Advantages: good synchronization, high ventilation efficiency and low airway pressure.

2. T mode of ventilator (Timed time control mode)

Also known as passive mode or time-controlled mode. That is, the machine controls people's breathing according to the set parameters, and people can only passively follow the work of the machine. This mode is mainly suitable for patients with weak breathing trigger ability. It is mainly suitable for patients with no spontaneous breathing or weak spontaneous breathing. That is, the BiPAP ventilator can perform invasive ventilation under certain conditions.

Note: The T function can drive the patient to breathe by the machine when the patient's breathing is weak and cannot breathe spontaneously, which is equivalent to a first aid mode.

3. S/T mode of ventilator (Spontaneous/Timed spontaneous breathing and time control automatic switching mode)

That is, when the patient's breathing cycle is less than the cycle corresponding to the backup ventilation frequency, the machine works in S mode; when the patient's breathing cycle is greater than the backup ventilation frequency, the machine works in T mode. For example (for example): BPM=10 times/min, breathing cycle=60 seconds/10=6 seconds, then the ventilator waits for 6 seconds, if the patient can trigger the ventilator within 6 seconds, the ventilator will work in S mode, on the contrary Then it is T mode. This mode is the most commonly used and is used for various patients related to breathing.

4. PC mode of the ventilator (Pressure Control pressure control mode)

When the patient's breathing cycle is less than the cycle corresponding to the backup ventilation frequency, the ventilator not only provides IPAP and EPAP, but also controls the patient's inspiratory time, but does not control the breathing time; when the patient's breathing cycle is greater than the backup ventilation frequency, it is T mode . It is mainly used for patients with fast respiratory rate, low tidal volume and hypoxemia. Only BiPAP Synchrony has this mode.

5. The CPAP mode of the ventilator (Continuous Positive Airway Pressure continuous positive airway pressure ventilation)

The patient has strong spontaneous breathing, and the ventilator provides the same pressure in both the inspiratory and exhalation phases to help the patient open the airway. It is mainly used for patients with OSAD obstructive sleep apnea syndrome, strong spontaneous breathing, and only need a little assistance from the ventilator.
