Spirometer with CO2 Analysis Instructable
This instructable introduces a spirometer with CO2 analysis capabilities, which measures the volume and speed of air inhalation and exhalation. In addition to standard spirometry, it includes capnographic features to gauge CO2 concentration in respiratory gases. The spirometer records expelled CO2 (up to 50,000 ppm) and exhale pressure in kilopascals using built-in sensors. These data […]
