In real time we will measure

The standard spirometry test is carried out in 4 stages:

Phases of a spirometry test:

  1. Complete inspiration (slowly, not forced)

  2. Maximum exhalation, complete and forced

  3. Maximum inhalation, complete and forced

  4. Normal breathing at rest

A curve is obtained that represents the flow and volume variation during phases 2 and 3 of the test.

  • PEF - (Peak Expiratory Flow) Maximum value of expiratory flow measured during a forced expiratory test

  • FEV1 - (Forced Expiratory Volume in 1 second) Volume of air exhaled in the first 1 second

  • FVC - (Forced Vital Capacity) Maximum volume of air that can be exhaled with force and maximum velocity after maximum inspiration

  • FEV6 - (Forced Expiratory Volume in 6 seconds) Volume of air exhaled in the first 6 seconds

  • plus more data available…

What does Spirometry measure?

  1. HOW MUCH AIR? (Volume…FVC…measured in “L”)

  2. HOW FAST IT IS EXHALED (FLOW…measured in “l/sec or l/min)

Why complete spirometry testing?

  • As part of a general patient’s health program.

  • As part of pre-employment screening.

  • As part of a regular check for employees working in high risk environments for lung disease.

  • As part of yearly evaluations of smokers over 40.

  • As part of a smoking cessation program.

  • As part of a bedside screening program.

  • Is there a history of dyspnea (shortness of breath) on exertion or at rest?

  • Is there a history of chronic cough or sputum production?

  • Is there a history of wheezing or chest tightness?

  • Is there a history of frequent colds or runny nose?

  • Is there an occupational exposure to inhaled dusts or chemicals?

  • As follow-up visits for patients with lung disease.

  • As management for all patients taking bronchodilators.

  • To evaluate he effects of air pollution.

  • As early detection of congestive heart failure.
