Vital Metrix has developed a breakthrough technology for cardiac patients, enabling sophisticated, non-invasive, essential cardiac output monitoring to be performed in a non-hospital environment. We believe that a cardiac output measurement that can be performed with no risk to the patient has the potential to both improve patient outcomes and reduce healthcare costs. We provide patient monitoring technology that can be easily integrated with existing, off-the-shelf pulse oximeters as input and produces a measurement of the patient’s cardiac output or stroke volume as an actionable output for the physician. The Vital Metrix technology can be applied to a range of cardiac diseases, with an initial focus on home monitoring for patients with Congestive Heart Failure.
Our innovative, patented (US8494829, US9060722) Vital Metrix technology takes cutting-edge digital signal processing techniques that were developed for Department of Defense aerospace applications and applies them to the human cardiovascular system. By utilizing sensors that patients are already capable of using at home, and extracting blood flow information, Vital Metrix will make it possible to cost-effectively monitor CHF patients at home. This will enable their cardiologists to adjust the medications that these patients rely on to survive more frequently and accurately, which will reduce hospitalization rates and lower costs for payers. More importantly, keeping these patients out of the hospital will improve their quality of life.
The pulse wave form captured by a pulse oximeter; whether the sensor is placed on the finger, earlobe, nasal alar, forehead, or another location; is driven by the pumping action of the heart driving blood flow through the circulatory system. The pulse waveform encodes changes in the blood pressure and flow rate at the location in the body where the measurement is taken. Our measurement technique uses a multi-element mathematical model of the human cardiovascular system. This mathematical model includes equations and parameters describing the blood flow from the heart and through the sequential elements of the cardiovascular system. The mathematical model is used to interpret the non-invasive measurements made with the pulse oximeter sensor. This enables an indirect measurement of the cardiac output, stroke volume, and pressure at various points in the cardiovascular system to be produced, along with a confidence level for the measurement.
