Aug 8 – Day 5 Forest, Heath and Moorland
The expedition team have made great progress over the past couple of days, and has now reached the testing camp on the Shira Plateau (#3 on the map below). At 11,500ft/3500m, this Lab in the sky will start to unveil significant adaptive responses in the research subjects. The ability of a discreet wearable to capture such dynamic responses continuously, under intense motion, in an extreme environment was a deciding factor in the Mayo Clinic selecting the VSM1 device as a key enabler in this exciting project.
Lead scientist Dr Bruce Johnson and his research team are investigating how the subjects react to the demands of high altitude environments and how these insights might be applied to better understanding and promoting health and wellbeing. As the subjects climb higher up the mountain they will breath air containing less and less oxygen, we can expect their speed and rate of ascent to slow and we can expect the researchers interest in the VSM1 signals to intensify!
The researchers are seeking to leverage nature in the form of Mt Kilimanjaro, and to simulate the oxygen deprivation (hypoxia) identified in serious cardiac events. Capturing vital sign data during the ascent will provide insights to the adaptive mechanisms employed by Human Physiology and contribute to the development of diagnostic and treatment strategies.
The VSM1 device captures Heart Rate (HR), Blood Pressure Wave (BPw), Blood Oxygenation (SpO2), Skin Temperature (ST), Blood Perfusion (PI) and Activity (Act). As an example, at the current altitude a graphical illustation of such data looks as shown below.Overnight montoring at approx. 12'000ft, with red showing higher HR, green lower HR, extension of bar shows intensity of activity and the blue/grey shading around shows modulation of BPw.
