Spirometry & Related Testing Equipment
Spirometer Definition
Any Device used to measure lung volumes and flows
Volume Displacement Spriometers
Water-Seal Spirometers (Collins, Stead-Wells)
Volume Displacement Spriometers
Water-Seal Spirometers
Bell factor Kymograph
32,160,1920 mm/min
ATPS to BTPS Potentiometer
Flow/Volume FV Loop
Spirometers
ATPS to BTPS Coversion
Actual values must be corrected to body temperature pressure saturated (BTPS)
Volume Displacement Spriometers
Water-Seal Spirometers
Problems Cracks → Leaks Positioning
Too high Too low
Infection Control Hoses Mouth Pieces Filters
