TODAYS TOPIC NAME CHAPTER: 05 ARTICLE: 5. 3 WORKING PRIINCIPLE OF SPIROMETER

What is spirometer? A spirometer is an apparatus for measuring the volume of air inspired and expired by the lungs. A spirometer measures ventilation, the movement of air into and out of the lungs. The spirogram will identify two different types of abnormal ventilation patterns, obstructive and restrictive. There are various types of spirometers which use a number of different methods for measurement (pressure transducers, ultrasonic, water gauge).

Working principle of spirometer �Spirometer is a biomedical device which measures the lung capacity and lung volume. The constructional feature of a spirometer is very simple. It mainly consists of a container which collects gas. To understand the basic working principle of a spirometer, we need to look into the basic construction of a spirometer. The water-sealed model is one of the popular types of spirometers. Let us discuss the construction and working of a water seal spirometer for the purpose of understanding.

benefits �Generally, a spirometry procedure is very safe. Some patients report a brief shortness of breath or dizziness after the test has been performed, but these will go away after a moment or two. �Patients who have recently suffered from a heart attack or any heart-related condition are not ideal candidates for a spirometry because the test requires some effort on the patient’s part. �In very rare cases, spirometry is known to trigger breathing problems in patients.
