aged asthma usually tends to be perennial and has a longer period of onset, but because of the poor tolerance to cold in the elderly, the incidence of winter is significantly higher than that of other age groups, and the severity of the symptoms in winter is greater than that of the others. Season。 Usually, the remission period of Senile Asthma is relatively short, especially the self remission rate is low. At the same time, the daily variability of asthma onset was smaller, and asthma at night was relatively less.
cough, expectoration, shortness of breath and episodes of paroxysmal nocturnal wheezing. In the TUCSON survey of asthma, 70% elderly asthma patients were found to have shortness of breath and wheezing, while only 11% of the non asthmatic elderly had shortness of breath and wheezing. In 63% of elderly patients with asthma, there were decades of cough or decades of cough before onset. However, due to the insensitivity of the elderly to the timely treatment, the correct diagnosis and timely treatment are delayed. Lee and other studies found that 14 of 15 elderly asthmatic patients had coughing and paroxysmal nocturnal wheezing, accompanied by chest tightness and chest tightness.
due to the dysfunction of the systemic and respiratory system of the elderly and the slowing of the nerve conduction velocity of the elderly, the slow response to the symptoms, the decrease of the threshold of the airway response and the insufficiency of the basic pulmonary function reserve, it may lead to severe severe asthma and even respiratory failure once the onset of the disease. The domestic study shows that the risk of severe asthma in elderly patients with asthma is almost 2~3 times as high as that of the non aged group. Therefore, it is important to be vigilant for the elderly asthma, and the timely diagnosis and active treatment are very important.
