Ventilators, which should also be classified according to different ways, such as noninvasive ventilators, invasive ventilators, and portable ventilators. According to the country, they are mainly divided into imported ventilators and domestic ventilators. If they are classified according to the method of use, they are divided into domestic ventilators and medical ventilators.

Lower limit of tidal volume alarm: range 0-2500ml, increment 5ml; When the exhaled tidal volume of the last breathing cycle is less than the set value, the machine will give an audible and visual alarm.
Upper limit alarm of respiratory rate: range 0-150bpm, increment 1bpm; When the monitored respiratory rate exceeds the set value, the machine will give an audible and visual alarm.
Lower limit alarm of respiratory rate: range 0-150bpm, increment 1bpm; When the monitored respiratory rate is lower than the set value, the machine will give an audible and visual alarm.
Upper limit alarm of airway peak pressure: range 0-120cmh2o, increment 1cmh2o; When the airway pressure is higher than the set value (more than 0.15s), the machine will give an audible and visual alarm immediately; In another breathing cycle, when the peak pressure is lower than the set value, the alarm stops.
Lower limit alarm of airway peak pressure: range 0-120cmh2o, increment 1cmh2o; When the peak pressure of the last breathing cycle is lower than the set value, the machine will give an audible and visual alarm.
Upper limit of PEEP: range 0-50 cmH2O, increment 1 cmH2O; The measured end expiratory pressure in the last respiratory cycle was higher than the set value, and the machine gave an audible and visual alarm.
Lower limit alarm of PEEP: range 0-50cmh2o, increment 1cmh2o; The measured end expiratory pressure in the last respiratory cycle was lower than the set value, and the machine gave an audible and visual alarm.
Upper limit alarm of oxygen concentration: range 21-100%, increment 1%; When the oxygen concentration monitored in the last respiratory cycle is higher than the set value, the machine will give an audible and visual alarm.
Lower limit alarm of oxygen concentration: range 21-100%, increment 1%; When the oxygen concentration monitored in the last respiratory cycle is lower than the set value, the machine will give an audible and visual alarm.

There are also different differences between home ventilator and medical ventilator. Home ventilator can be divided into two categories, one is simplified medical ventilator, the other is noninvasive ventilator. According to the situation of patients, different ventilator can be selected.
Relatively speaking, medical ventilators are mainly used in hospitals with complex and diversified functions. They are suitable for all kinds of diseases and have a wider range of applications. Of course, they are more expensive.
As for invasive ventilator and noninvasive ventilator, invasive ventilator is connected to patients through endotracheal intubation, so it needs to open endotracheal intubation and direct nasal intubation, which is mainly suitable for patients with severe respiratory failure.
Noninvasive ventilator is connected with the patient through the mask, which will not cause damage to the patient's body, and is suitable for patients with mild to moderate respiratory failure.
The above is the main types of ventilator and the symptoms used, patients or medical staff according to the need to buy suitable for the use of ventilator!
