2017-06-22 02:53:21 | BioPortfolio

Summary

Particulate matter(PM) exposure has been shown to increase the morbidity and mobility of a variety of respiratory diseases, including COPD and asthma. This study focus on the effects of PM on the pulmonary function and acute exacerbation of COPD and asthma patients in China, where PM exposure is much heavier than the United States and European countries.

Description

Particulate matter(PM) exposure has been shown to increase the morbidity and mobility of a variety of respiratory diseases, including COPD and asthma. This study focus on the effects of PM on the pulmonary function and acute exacerbation of COPD and asthma patients in China, where PM exposure is much heavier than the United States and European countries. This study is an observational study which lasts 3 years. Primary outcome measures:Change in spirometry (FEV1) of COPD, asthma patients and healthy volunteers in response to different exposure doses of PM.

Medical and Biotech [MESH] Definitions

Hypertrophy and dilation of the RIGHT VENTRICLE of the heart that is caused by PULMONARY HYPERTENSION. This condition is often associated with pulmonary parenchymal or vascular diseases, such as CHRONIC OBSTRUCTIVE PULMONARY DISEASE and PULMONARY EMBOLISM.

Hospital department which is responsible for the administration of diagnostic pulmonary function tests and of procedures to restore optimum pulmonary ventilation.

Excessive accumulation of extravascular fluid in the lung, an indication of a serious underlying disease or disorder. Pulmonary edema prevents efficient PULMONARY GAS EXCHANGE in the PULMONARY ALVEOLI, and can be life-threatening.

Narrowing below the PULMONARY VALVE or well below it in the infundibuluar chamber where the pulmonary artery originates, usually caused by a defective VENTRICULAR SEPTUM or presence of fibrous tissues. It is characterized by restricted blood outflow from the RIGHT VENTRICLE into the PULMONARY ARTERY, exertional fatigue, DYSPNEA, and chest discomfort.

Backflow of blood from the PULMONARY ARTERY into the RIGHT VENTRICLE due to imperfect closure of the PULMONARY VALVE.
