2. Spirometer - Wikipedia

   en.wikipedia.org/wiki/Spirometer

   A spirometer is the main piece of equipment used for basic Pulmonary Function Tests (PFTs). Lung diseases such as asthma , bronchitis , and emphysema may be ruled out from the tests. In addition, a spirometer often is used for finding the cause of shortness of breath, assessing the effect of contaminants on lung function, the effect of ...

3. Incentive spirometer - Wikipedia

   en.wikipedia.org/wiki/Incentive_spirometer

   An incentive spirometer is a handheld medical device used to help patients improve the functioning of their lungs. By training patients to take slow and deep breaths, this simplified spirometer facilitates lung expansion and strengthening. Patients inhale through a mouthpiece, which causes a piston inside the device to rise.

4. Spirometry - Wikipedia

   en.wikipedia.org/wiki/Spirometry

   Spirometry (meaning the measuring of breath) is the most common of the pulmonary function tests (PFTs). It measures lung function, specifically the amount (volume) and/or speed (flow) of air that can be inhaled and exhaled.

   The medical equipment maker recalled certain models of its AirLife Manual Resuscitators, a single patient-use device intended for respiratory support, due to a manufacturing defect. The use of the ...

6. Lung volumes and capacities - Wikipedia

   en.wikipedia.org/wiki/Lung_volumes_and_capacities

   The tidal volume, vital capacity, inspiratory capacity and expiratory reserve volume can be measured directly with a spirometer. These are the basic elements of a ventilatory pulmonary function test. Determination of the residual volume is more difficult as it is impossible to "completely" breathe out.

7. Helium dilution technique - Wikipedia

   en.wikipedia.org/wiki/Helium_dilution_technique

   The amount of He in the spirometer is known at the beginning of the test (concentration × volume = amount). The patient is then asked to breathe (normal breaths) in the mixture starting from FRC (functional residual capacity), which is the gas volume in the lung after a normal breath out. The spirometer measures helium concentration.

8. Vital capacity - Wikipedia

   en.wikipedia.org/wiki/Vital_capacity

   Output of a spirometer. Vital capacity (VC) is the maximum amount of air a person can expel from the lungs after a maximum inhalation. It is equal to the sum of inspiratory reserve volume, tidal volume, and expiratory reserve volume. It is approximately equal to Forced Vital Capacity (FVC). [1] [2]

9. Pulmonary function testing - Wikipedia

   en.wikipedia.org/wiki/Pulmonary_function_testing

   Pulmonary function testing (PFT) is a complete evaluation of the respiratory system including patient history, physical examinations, and tests of pulmonary function. The primary purpose of pulmonary function testing is to identify the severity of pulmonary impairment. [1]
