Are e-cigarettes and vapes really less harmful than traditional cigarettes? New study results, based in part on measurements with pulmonary function devices from GANSHORN Medizin Electronic GmbH, suggest that the supposedly safer alternative is more dangerous than previously assumed. These…
In the context of pulmonary function testing, a Z-score and LLN (Lower Limit of Normal) are statistical measures used to interpret test results: Z-Score A Z-score represents the number of standard deviations a value is from the mean of a…
A body plethysmograph is a medical device used to measure various aspects of lung function. Here are the key parameters it can measure: Lung Volumes: It can measure total lung capacity (TLC), functional residual capacity (FRC), and residual volume (RV).…
When selecting a good pulmonary function test (PFT) filter, several key parameters need to be considered to ensure accurate, reliable, and safe testing. Here are the important parameters to consider: 1. Filtration Efficiency Bacterial/Viral Filtration Efficiency (BFE/VFE): The filter should…
The basic Pulmonary Function Test (PFT) measurement parameters and their explanations are as follows: Forced Vital Capacity (FVC): Definition: The total amount of air that can be forcibly exhaled from the lungs after taking the deepest breath possible. Explanation: FVC…
Over time, different technological variants have been developed that allow a spirometric measurement to be carried out.These basic methods exist: Mechanical Spirometers: These use moving parts to measure air flow and volume. Examples include bellows and piston spirometers. Pneumotachographs: These…
