While great advances in medicine has been made in the past century, the overall infrastructure of the healthcare system has not progressed. Patients (who are not feeling well) are still expected to travel to a centralized location for discrete, reactionary-based care where the healthcare provider only has a brief window to assess the patient’s health. Unless the symptoms are overt at the time of examination, the subjective evaluation relies heavily on the self-reporting of symptoms from the patient. This often results in delayed or improper diagnoses. In contrast, we know that physiological signals precede clinical deterioration. We have developed a suite of low-cost, unobtrusive, Band-Aid©-like physiological sensors to continuously monitor patients’ cardiovascular and pulmonary functions. We seek to continuously quantify subtle physiological changes to predict, and eventually prevent, the onset of acute clinical events.
