Spirometry
Definition:
A spirometer is a transducer used to measure the volume and/or flow of air that can be inhaled and exhaled
Amplitude: -10L/s to 10L/s
Typical Use:
Clinically, spirometers can be used to assess conditions such as asthma, cystic fibrosis, and chronic obstructive pulmonary disease (COPD). Two very common spirometry-based measures are the forced vital capacity (FVC) test, which examines the amount of air a subject can move into and out of the lungs, and pressure-volume curves, which evaluate the compliance of the lungs.
Typical BioRadio Configuration:
- When using aspirometer, make sure you are set to Advanced View when programming your BioRadio.
- Coupling: DC
- Range: ±280 mV
Typical Setup:
Step 1:
Zero the spirometer before starting and then collect a baseline signal of the subject breathing normally. Step 2:
Instruct the subject to sit up as straight as they can through the duration of data collection in order to ensure a change in body position doesn’t skew the data.
