Altitude illness is generally characterized by symptoms that last for only a few days and include nausea, headaches, dizziness, shortness of breath, fatigue, and the swelling of hands and feet. Life-threatening conditions such as pulmonary and cerebral edema also occasionally arise. Dr. Johnson's findings are expected to benefit the military, NASA, and certain medical specialties because adaptation to high altitude has similarities to the hypoxemia that has been identified in a number of chronic respiratory-related conditions.
"Diseases such as chronic heart failure, lung disease, and obstructive sleep apnea all have ties with hypoxia and thus research on predictors of high altitude illness may be helpful for these diseases as well," said Paul Kennedy, Chief Executive Officer of VivoMetrics. "The respiratory cardiopulmonary data captured from the LifeShirt allow us to evaluate the physiologic effects of altitude and low oxygen in a way that cannot be duplicated in a research lab."
The LifeShirt(R) System is the first non-invasive ambulatory monitoring system that collects, records, and analyzes a range of cardiopulmonary functions (such as pulmonary function, electric activity of the heart, posture) continuously in real-time. Sensors are embedded in a lightweight, machine washable garment that collects the cardiopulmonary data. There are optional peripheral devices that can measure EEG/EOG, leg movements, temperature, blood pressure, blood saturation, end tidal CO2, and cough.
VivoMetrics, founded in 1999 and based in Ventura, California, provides
wearable, non-invasive products and services, using its proprietary
LifeShirt(R) technology, which continuously monitor vital, life-sign
functions, such as heart rate, ECG, respiration rate, flow, and volume,
posture, and activity. The company's offerings, based on patented, field-
tested technologies, were initially focused on
