The human body is an amazingly complicated machine, capable of adapting and responding to various stressors and environmental conditions. Even in extreme situations the body is able to adjust core physiological processes and systems to ensure optimal function, and ultimately, survival. When studying human physiological response the most basic measurements, such as ECG and respiration, can hold huge amounts of information. But, their value is much greater when integrated with other physiological measurements such as blood pressure, oxygen saturation and respiratory gas concentrations.
However, accurate co-registration of physiological data is no trivial pursuit. Moreover, the complexity of such research endeavors is compounded when we venture out of traditional laboratory spaces and seek to study human response and adaptation in extreme environments. Sensors and systems must offer practical application and reliable data collection -- moreover, data storage and management is of critical importance.
In this webinar sponsored by ADInstruments, Dr. Trevor Day, Associate Professor of Physiology at Mount Royal University in Calgary Alberta, shares his research on the effects of tilt, exercise and high altitude on respiratory sinus arrhythmia (RSA). These case studies serve as representations of more complex applications of human physiologic monitoring, in particular, his trek to Everest Base Camp where he and his research team monitored and tracked acclimatization in the context of high altitude hypoxia. During this expedition multiple physiological measures were recorded simultaneously on both rest and exercise days in order to test for signs of altitude sickness. Dr. Day shares his experiences from this exciting study and others conducted at his lab at Mount Royal to offer perspective regarding the importance of being able to record and integrate multiple data streams simultaneously.
