Background
Noninvasive ventilation generally refers to a mechanical ventilation mode in which a ventilator is connected to a patient through a nasal mask or an oronasal mask, and positive pressure support is provided by the noninvasive ventilator to accomplish ventilation assistance, the main difference from invasive ventilation being that the latter is connected to the patient through an airway tube or tracheostomy tube. In invasive ventilation, the airway intubation is easy to cause throat edema and airway mucosa to be damaged, and the tracheotomy can leave a incised wound, and the infection probability is increased due to the drainage effect of the catheter. The noninvasive ventilation has no wound, has no drainage effect of a catheter, is simple and convenient to operate, is easy to accept by patients, is mainly used for acute or chronic respiratory failure, sleep apnea syndrome, acute exacerbation of chronic obstructive pulmonary disease and related diseases, has good curative effect in off-line treatment for assisting invasive ventilation, and is widely applied to the medical fields of first aid and treatment. The mask exhaust holes of the current noninvasive breathing machine are all arranged on the mask and are responsible for exhausting the exhaled air of patients. Without the vent, the patient may repeatedly inhale his own exhaled air, resulting in an increase in the partial pressure of carbon dioxide in the blood. The noninvasive ventilator has large air pressure and flow velocity, and the exhaust holes are arranged on the mask, so that the noninvasive ventilator can help effectively exhaust carbon dioxide and correct hypercarbonated blood. However, clinically, there are some patients with hypocarbonic emia, which causes respiratory alkalosis, or central sleep apnea. In this portion of the patient, the vent is on the mask which further reduces the patient's carbon dioxide and is no longer suitable. There is no method for correcting respiratory alkalosis and central sleep apnea by means of medical instruments in clinic at present.

The utility model can prevent the carbon dioxide in the blood from being reduced too low, and can be applied to patients with central sleep apnea. The partial pressure of carbon dioxide may rise 3-6mmHg during sleep over awake periods. The initiating factor in the occurrence of central sleep apnea is hypersensitive ventilation, and the partial pressure of carbon dioxide in blood is reduced to a waking level, and sleep apnea occurs.
