A spirometer is a team of medical tests is often used to measure and analyze the functions of the lung. This plastic device used to measure the amount of air a person can have in their lungs. It also measures how a patient moves air into and out of your respiratory tract . Generally, people who are suspected of having symptoms associated with lung disease often tested using the spirometer. Spirometers also used to diagnose other lung diseases, including asthma , chronic bronchitis and emphysema. In addition, the computer is used to determine the effectiveness of certain prescription drugs for lung disease . The objectives of the spirometer are :

· Detection of lung disease

The spirometer can be used to detect most of the lung disease. Lung problems often cause lung capacity to decrease with time. The device allows doctors and patients to monitor the progression of the disease when it starts to occur. In the context of therapy, it is important to provide a baseline. Therefore, when the patient experiences a sudden decline in the volume of the lungs, is a strong indication that something is wrong.

· Assist breathing

The spirometer is perfectly designed to help patients learn to take deep breaths. The device is simple and requires very little training. When used properly , offers surprising results. Help take a deep breath or sustained maximum inspiration. Patients learn to hold your breath for a few seconds .

· Optimized Pulmonary Ventilation

Inflation can be beneficial for the lungs. When you have bigger lungs , the air will manage to reach all parts of the lungs. It is thus possible for the oxygen to find their way into the bloodstream more efficiently .

· Best cough

Cough allows the lungs to move and get rid of toxins , fluids and contaminants. When you can not use their lungs to breathe heavily and deeply , cough can be unproductive. This may result in an increased risk of infection. Or satiety after a long illness , this problem is noticed when patients receive sedatives that lead to slow or weak diaphragm.

· Preventing pneumonia

Care of the lungs is very important after surgery to prevent runoff into the lungs, and remains closed if the cell fluid or mucus accumulates pneumonia may develop. Therefore, after the surgery, patients are encouraged to use spirometers , cough (if necessary) and breathe deeply . This helps to get rid of fluid and mucus in the lungs.
