Background

Oxygen therapy equipment is often used for oxygen therapy of patients in the nursing process of respiratory medicine, and the oxygen therapy is a method of inserting a special bilateral nasal catheter into a double-nostril for oxygen inhalation. The main effects are to increase the arterial oxygen partial pressure, improve the oxygen supply of the human body and reduce the respiratory and circulatory burden increased by compensating for the hypoxia. The reasons for oxygen deficiency and the oxygen therapy effects are different for different diseases. The oxygen therapy effect is obvious for patients with oxygen absorption disorder or insufficient ventilation caused by the influence of lung tissue diseases on ventilation function; for those with oxygen transport disorder caused by circulatory insufficiency or anemia, oxygen therapy has a certain effect, but the problem of oxygen deficiency cannot be fundamentally solved; the oxygen therapy method comprises five methods, which are respectively as follows: nasal catheter oxygen therapy: generally, a thin and soft catheter is used, whether a tube cavity is blocked or not is checked, and the nostrils of the children are cleaned before application. When the nasal catheter is put into the nose by about 1cm, namely, the nose opening is positioned in the nasal vestibule, the oxygen flow is 0.5-1L/min, the inhaled oxygen concentration is about 30 percent, and the oxygen is atomized and supplied through a mask: the nasal catheter has poor oxygen supply effect or the infant refuses to use the nasal catheter, oxygen can be supplied through the mask, the oxygen flow is 1-3L/min, and the inhaled oxygen concentration is 50% -60%. Recently, this method is often combined with aerosol inhalation, where the oxygen supply by aerosol not only humidifies the inhaled oxygen, but also by aerosol administration, oxygen masks: for infants or uncooperative patients, an organic glass hood is preferably adopted, and the head is covered into the hood from the upper part of the neck. The top of the cover is provided with an oxygen inlet jack and a plurality of air holes, and the oxygen concentration can be adjusted by controlling the amount of the inlet air. The oxygen flow is 4L/min, the oxygen concentration is about 45 percent, and the oxygen account: when higher concentrations of oxygen need to be inhaled. The transparent plastic film is made into a small tent with a square of 40-60 cm and is placed on the upper half body or the head and face of the infant patient without being completely sealed. Oxygen is input at 3-5L/split flow, the oxygen concentration in the tent can be maintained at about 40% -50%, no carbon dioxide is accumulated, and the special oxygen supply method comprises the following steps: including various positive pressure oxygen supplies.
