How to know if you have asthma.

Asthma is a condition that can affect anybody. That is why you need to make sure that you take care of your respiratory tract so that you can avoid this condition. If you feel you are going through something similar to this condition then you need to seek the advice of a specialist. This is because there are ways through which the diagnosis for asthma can be done. The first thing your specialist will do is to test the capacity of your lung. This will help in determining how severe your asthma is.


Steps in asthma diagnosis

You will be asked by your lung specialist to breathe into a closed tube that is connected to a machine. This machine will be able to measure the speed and the total volume of air expelled from your lungs. The fact that there is nothing wrong with the level of air you expel does not mean that all is okay with your bronchial tubes. This means that your bronchial tubes may be blocked and this may prevents air from being exhaled at the normal rate that is required and this usually leads to asthma.


The use of bronchodilator drug

The bronchodilator drug is used when the first test conducted by an asthma patient shows that there is abnormality in his breathing. The bronchodilator will be inhaled and the patient will be made to repeat the test. A 20% improvement in the rate at which air is exhaled means that the patient has asthma.


Asthma machines

Spirometer is an inexpensive asthma detection machine. There are also many other ones that are quite expensive, some of these machines may be the sophisticated high-tech computer that can be used to record complete functioning of the lungs. Breathe monitoring machines can also be used to diagnose and monitor the progress of the asthma patient.

The peak flow meter is another asthma machine that can be used to monitor air flow through the bronchial tubes in the lungs. This machine enables the asthma patient to monitor their lungs easily at home. When you are looking for the right means to monitor the different stages of an asthma attack and what could be responsible for triggering the attack then you need to make use of the peak flow meter. Apart from using the peak flow meter to measuring the above events, you can also use the machine to adjust your daily medication with the machine according to your doctor’s recommendation. You can only make use of the peak flow machine if you are having the acute or chronic asthma. So if your asthma is the mild one then forget the Peak flow machine.
