Who can use a Incentive Spirometer

Intension use of the Incentive Spirometer: 

To do breathing training.

Breathing training is divided into two types: inhalation training and exhalation training: inhalation is an active process, which requires active breathing.
Compression expands the chest cavity and reduces the pressure in the lungs; when the pressure in the lungs is lower than atmospheric pressure, air is drawn into the lungs. and
The tact of exhaling is the same as inhaling because of the pressure difference, but exhaling is because the pressure in the lungs is greater than the atmospheric pressure. threw up
Qi breathing training has a significant effect on the efficiency of gas exchange in the body.

User of Three Ball Spirometer as below: 

Pulmonary embolism\atelectasis\pneumonia\pulmonary obstruction\athletes\students before and after chest surgery
Physical training \ lung capacity exercise for office staff \ shortness of breath \ long-term smoking with poor lung function. 

Breathing training purpose:
1. It is beneficial to lung expansion. After part of the lung tissue is removed, it can promote the rapid expansion of the remaining lung and eliminate the residual cavity.
2. To expand the thorax and to form negative pressure in the chest, which is conducive to the expansion of the lungs and promotes the re-expansion of the atrophied small alveoli to prevent atelectasis.
3. Changes in intrapulmonary pressure, increased pulmonary ventilation, increased tidal volume, slowed breathing rate, and reduced postoperative wound pain caused by excessive breathing.
4. It is beneficial to gas exchange and diffusion, and improves systemic supply.
5. Promote effective cough.
