Oxygen therapy is primarily aimed at correcting hypoxemia, reducing work of breathing and reducing heart load, preventing and reversing tissue damage and organ dysfunction due to hypoxia, while maintaining the patient's mobility as much as possible. The main risks of oxygen therapy are ineffective correction of hypoxemia, aggravation of carbon dioxide retention, and even oxygen poisoning. The standard oxygen therapy principle is to ensure the safety and the effectiveness of the oxygen therapy. Two famous clinical control tests internationally can clearly prove the effectiveness and corresponding conditions of the family oxygen therapy, and are scientific bases for bringing the family oxygen therapy into the national health care system in many countries.
In the 1970 s, studies of the National Institutes of Health (NIH) nighttime oxygen therapy trial (not) and the british medical research council clinical trial (MRC) showed that five-year survival rates of COPD patients with chronic hypoxemia were improved in proportion to the duration of oxygen therapy (hours) per day. The survival rate of patients who do not undergo adjuvant oxygen therapy is worst; survival rates were better for patients receiving oxygen therapy 12 to 15 hours a day; the survival rate of patients receiving nearly 24 hours of continuous oxygen therapy with mobile oxygen systems is best.
The national treatment guidelines of the national institute of health and clinical optimization (NICE), the American Thoracic Society (ATS), the European Respiratory Society (ERS), and the british national institute of health and clinical optimization (NICE) have established the prescription standards and treatment goals for home oxygen therapy. The Chinese medical authoritative textbook also brings the indications and indications of oxygen therapy into the textbook of internal science, and the core contents of the national guidelines are different from the standards established by the American Thoracic Society (ATS). Arterial partial oxygen pressure PaO in stable phase after hypoxemia or COPD acute exacerbation in COPD disease progression2<55mmHg or arterial oxygen saturation SaO2<88% or partial arterial blood oxygen pressure PaO255-59mmHg with pulmonary heart disease, polycythemia, pulmonary hypertension, etc. The treatment target is: guarantee PaO during rest, sleep and activity2>60mmHg(SaO2>90 percent), the oxygen inhalation time per day is more than 15 hours, preferably 18 to 24 hours.
According to the relevant documents at home and abroad, the oxygen treatment quality management means is generally lack and the monitoring effect is poor in the aspects of compliance and treatment effect. The main points are as follows: whether the patient is inhaling oxygen, how long the time of inhaling oxygen, how much the flow rate, whether the doctor's advice is followed, and how effective the patient is inhaling oxygen (degree of blood oxygen saturation, respiratory rate, symptom improvement, mental state, appetite, etc.)
The utility model aims at the above problem, whether the real-time supervision problem of oxygen uptake, oxygen uptake time and respiratory frequency etc. is solved in key. In particular, clinical studies show that the monitoring of the variability of the respiratory rate can effectively predict the acute onset of COPD and provide an effective means for early intervention.
