Blowing balloons can increase vital capacity and help improve lung function. Especially for patients after lung surgery, balloon blowing can be beneficial to the recovery of the disease and avoid postoperative dyspnea and atelectasis. After 3~4 days of balloon exercise, lung function can usually be improved. In addition to non-balloon exercise, you can also do lip contraction breathing and abdominal breathing, which are helpful to improve lung function. People with low lung function should pay attention to avoid inducing factors such as colds and colds.
When blowing a balloon, you usually take a deep breath until you can't breathe any more, and then hold your breath. Blow into the balloon mouth slowly until it stops blowing. Keep the frequency at 15 to 20 times per minute and practice 2 to 3 times a day. What needs to be reminded here is that the speed of blowing balloons is not fast, and the number of times is not doing it, but trying to blow out the air. This is because this is practicing abdominal breathing. If you work part-time for a long time, it will help to reduce the residual lung volume, improve lung function and delay the progress of chronic lung obstruction.
