Diagnosis of Asthma

Blood analysis may show increase in the number of eosinophils (Eosinophil is a specific type of white blood cell that increases in allergic reactions).

  • Sputum examination may show increased eosinophils.
  • The level of a certain antibodies can be elevated.
  • Chest X ray may show abnormality in the airway.
  • Arterial blood gas analysis shows decreased oxygen concentration in blood.

Pulmonary function tests (lung function tests) are helpful in judging severity of airway obstruction. To do this test a spirometer is used and the test is often called spirometery. A spirometer is an instrument that measures the maximum volume one can exhale after breathing in as much as one can. There are various values that are calculated and the interpretation of the test is done looking at a combination of values. Some of the common values looked at are as follows:

Forced Vital Capacity or FVC: This is the total volume of air one can exhale after breathing in as much as one can inhale.

Forced Expiratory Volume in One Second, or FEV1: This measures the volume of air one can exhale in the first second. In general, the more air you breath out during the first second of a full exhalation, the better.

Asthma symptoms are less severe and you will eventually learn how to live with them. A good asthma attack is when this gets out of hand, your own coughing violently, cant inhale and the last two individuals I saw come with an asthma attack were upon on the floor clutching in their throat and chest.

Another consideration is the humidity level in the home, which can be measured using a hygrometer. A dry atmosphere has health concerns and it is a humidifier that is used to add moisture to the air in the home. A humidifier can be either for the whole house or a small humidifier ideal for a room.
