Air quality early warning method and device for patient with chronic obstructive pulmonary disease

Abstract

The invention provides an air quality early warning method for a patient with a chronic obstructive pulmonary disease. The method comprises the following steps that the time, the motion speed of the patient, the accelerated speed and the distance change information of the patient are acquired, and a motion state of the patient is judged, so as to obtain the energy consumption N of a human body under the specific activity intensity level; 2) the age, sex and height characteristic parameters of the patient are acquired, and the energy E consumed in unit time is calculated by the following formula; 3) the concentration C of pollutants in air of an activity space of the patient is measured, and the daily average exposure dose ADD of the pollutants is calculated by the following formula; and 4)the health risk R of the human body exposed to a certain pollutant is calculated according to the daily average exposure dose ADD of the pollutants, the calculated health risk R of the human body exposed to the certain pollutant is compared with a risk threshold value, and if the health risk R is larger than the threshold value, an alarm is triggered to ensure the patient with the COPD to avoid the disease risk.

Description

technical field [0001] The invention relates to a medical device, in particular to an air quality early warning method for patients with chronic obstructive pulmonary disease. Background technique [0002] The most direct and easily felt consequence of environmental pollution is to degrade the quality of the human environment and affect human quality of life, health and production activities. Chronic obstructive pulmonary disease (COPD) is a common and frequently occurring chronic airway disease, which poses a serious threat to people's quality of life and health. Harmful gases, smoking, dust, etc. are important risk factors for the onset of COPD. Therefore, environmental pollution has a great health risk for COPD people with chronic obstructive pulmonary disease. If we want to avoid the health hazards caused by ambient air pollution , it is necessary to measure the individual behavior pattern track and real-time air quality and carry out real-time risk control, and the hea...
