S mode is also called autonomous trigger mode or synchronous mode. That is, people control the work of the machine through their own spontaneous breathing (the machine provides inspiratory pressure when inhaling, and the machine provides expiratory pressure when exhaling). The working frequency of the machine is completely controlled by the patient's own breathing, and the ventilator is closely related to the patient's breathing rate. Full synchronization is maintained, but if the patient stops breathing spontaneously, the ventilator also stops working. This mode is mainly suitable for patients with good respiratory triggering ability.
T mode is also called passive mode or time control mode. That is, the machine controls the person's breathing according to the set parameters, and the person can only passively follow the work of the machine. This mode is mainly suitable for patients with weak breathing triggering ability.
S/T mode is sync/time mode. In this mode, if the patient is breathing well on his own, the ventilator will maintain complete synchronization with the patient's respiratory rate; if the patient's breathing is unstable or stops, the ventilator will control ventilation to the patient according to the preset pressure, respiratory rate, and inhalation-exhalation ratio. .
In modern clinical medicine, ventilators, as an effective means of artificially replacing autonomous ventilation function, have been widely used for respiratory failure caused by various causes, anesthesia respiratory management during major surgery, and Supportive treatment and emergency resuscitation occupies a very important position in the field of modern medicine. The ventilator is a vital medical equipment that can prevent and treat respiratory failure, reduce complications, and save and extend the patient's life.
