Background
Tracheotomy is often used for rescuing patients with acute critical diseases and dyspnea caused by respiratory tract obstruction or retention of respiratory tract secretion and respiratory dysfunction, but after tracheotomy, the phenomena of dryness, sticky secretion and the like can occur on the tracheal mucosa due to obvious moisture loss of the respiratory tract, thus forming phlegm plugs or phlegm scabs, even the situations of airway obstruction and the like can occur, which threatens the life safety of the patients, so that in the nursing process of the tracheotomy patients, the humidification of the airway is critical, because inhaled air is heated, filtered and moistened by ciliated epithelial cells of the nose and the upper respiratory tract during normal breathing of a human body, however, the tracheotomy of the patients bypasses the humidification functions, and the inhaled air is cool and dry.

However, because the existing high-flow device has higher gas flow rate, the accessed oxygen and air are mixed and diluted to easily cause lower oxygen concentration, and the continuous supply of oxygen can also cause great waste in the expiration stage of a patient, therefore, for the patient with portable, transportation and high oxygen demand, if the expiration and inspiration states of the patient can be determined through real-time detection, and oxygen can be accurately supplied in the inspiration stage, the problems can be well solved.
In addition, the high-flow device needs to consider the specific situations of the patient in practical application, such as heavy illness state, weak respiration, and difficulty in forming obvious respiratory airflow in the airway, and continuous oxygen supply is needed.
