Expand-a-lung is a device that helps improve respiratory function through special exercises. The device has a silicone mouthpiece and a moving part that increases and decreases breathing resistance to strengthen respiratory muscles and increase lung capacity and efficiency. It is recommended for athletes and those with limited lung function, such as COPD patients. The exercises should be done before eating or certain exercises and the device should be washed after each use.
Expand-a-lung is a device that helps people improve their respiratory functions. Many athletes and people with limited lung function, such as those with chronic obstructive pulmonary disease (COPD), can strengthen and improve their respiratory function by doing special exercises. Expand-a-lung can help a person do this. The device is approximately four inches long (approximately 10.2 cm) and has a silicone mouthpiece, as well as a moving part that helps increase and decrease breathing resistance. It is this resistance that can help a person strengthen their respiratory muscles and can help them achieve greater lung capacity and respiratory efficiency.
To increase lung capacity, the Expand-a-lung exercises the respiratory muscles. When a person inhales, the diaphragm and external intercostal muscles expand the chest to allow the lungs to fill with air. During the exhalation at rest, the muscles relax, allowing the chest to return to its normal shape, thus expelling the air. With resistance, however, the intercostal muscles, as well as other muscles, must contract to expel air. Expand-a-lung works to increase resistance during inhalation and exhalation to strengthen muscles and increase respiratory efficiency.
To experience the strengthening effect of the device, a person must do the exercises that are recommended. To do these exercises, an individual must begin by adjusting the breathing resistance to her preference. Then you need to breathe out and inhale to work the respiratory muscles. For the exercises to work efficiently, the breathing resistance on the device needs to be challenging without restricting airflow too much. The instructions also recommend that a person pause between breaths using the device in order to recover.
Expand-a-lung works by using increased resistance to cause the target muscles to expand the lungs and chest more than is normally needed. Similarly, breathing out also causes the chest and lungs to contract more than normal. These exercises help increase the amount of air that is breathed into the lungs, as well as allow more air to be exhaled during exhalation. This increased inhalation and exhalation allows more oxygen to be taken in and more carbon dioxide to be expelled with each breath. The result is a person who has trained their lungs and respiratory muscles to be more efficient.
For an athlete, increasing lung capacity can help give him an advantage. With more lung capacity, he can achieve greater endurance while engaging in his particular activity. People with COPD can increase their lung capacity to make breathing more efficient. It is recommended that the exercises be done before a person eats and before a person performs certain exercises. The device should also be thoroughly washed with antibacterial soap after each use.
