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.
