Cough time with the throat, not only can not effectively clean up the respiratory secretions, but also lead to sore throat hoarseness, resulting in a cough time extension, the formation of a vicious circle, and aggravating the symptoms.

An effective and complete cough should be divided into the following steps:

Step 1: Take a deep breath and gently expand your abdominal muscles. Feel comfortable, take as deep as possible, and then hold your breath for 3 seconds.

Step 2: forcefully contract the abdominal muscles to discharge the gas, cause a cough, if there is residual air and then shrink the lip breath.

Step 3: Generally inhalation can cough three consecutive times, and then calm breathing for a moment.

Need to be reminded, have a cerebrovascular rupture, embolism, or hemangioma history should avoid hard cough. In the special period of the epidemic, it is very important to avoid cross infection caused by cough and grasp the correct cough method.

During the SARS outbreak in 2003, the cough was adopted and promoted in Hong Kong, China, and tissues were still used in many local households: That is, when not wearing a mask, cough or sneeze to try toward the ground. If possible, cough to the basin or urinal, and wash the basin or urinal immediately after coughing. This position may be a more hygienic and easy-to-operate way when coughing or sneezing occurs.
