What Is Spirometry? What Are Its Uses:

 CBSE 11th Biology Chapter 17

A diagnostic test is a check-up to identify a person’s weaknesses and strengths to describe a disease condition.

Diagnostic test:

Doctors use a variety of diagnostic methods to diagnose the disease.

- Spirometry is the most   frequent test to check   the functioning of the   lungs. - English physician John   Hutchinson discovered   spirometry in 1846.

Spirometry

Doctors refer to spirometry using other names, such as pulmonary function test(PFT) or lung function test (LFT).

Spirometry measures lungs Function, air volume, and airflow. It helps to observe the breathing patterns of the lungs.

Spirometry is a simple device.

Components of Spirometry:

The basic components of spirometry are the mouthpiece, a hose or tube and an electron device used to measure and calculate Spirometry parameters.

The test works by measuring airflow into and out of the lungs.

Working Principle of Spirometry

The patient breathes air into the tube via the mouthpiece. During each cycle of inhalation and exhalation, the jar moves up and down.

– It depends on the   amount of air inhaled or   exhaled into the air   inside the glass jar. – The weight attached to   the string moves up and   down depending on the   movement of the jar.

- Then this device   records the amount of   inhaled and exhaled air   and speed of breath. - The election device of   spirometry shows the   readings.

Spirometry helps identify asthma, pulmonary fibrosis, cystic fibrosis, chronic obstructive pulmonary disease (COPD), and other health conditions.

Benefits of Spirometry:

Frequent spirometer use can improve lung functioning and reduce the risk of lung problems such as pneumonia, atelectasis, and lung infections.

It increases the oxygen saturation.

The patient may feel short breath or dizzy for a moment after performing the test. Sometimes it may trigger severe breathing problems.

Disadvantages of Spirometry:
