Technology for measurement of static and dynamic parameters of both respiratory physiology and breathing behavior, make for objective evaluation of dysfunctional breathing and the outcomes of self-regulation interventions. This course includes: Principles – basic hardware physics, measureable physiological parameters, clinical applications, and educational applications; Measurement – respired volumes, ventilatory volumes, ventilatory capacity, respiratory muscles, metabolism, PO2, SaO2, SpO2, PaCO2, HbCO2, HHb, ETCO2, pH, and electrolytes; Instrumentation – capnometry, pH meters, spirometry, strain gauges, thermistors, thermocouples, CO-oximetry, pulse oximetry, brain oximeters, pneumotachography, polarography, respirometers, impedance pneumography, electromyography (EMG), calorimetry, amplifiers, and electrodes; Precautions – measurement misunderstandings, data misinterpretations, instrumentation limitations, and error analysis.
