SYSTEMS AND METHODS FOR NON-INVASIVE BLOOD PRESSURE MONITORING |
摘要 |
According to embodiments, systems and methods for non-invasive blood pressure monitoring are disclosed. A sensor or probe may be used to obtain a plethysmograph or photoplethysmograph (PPG) signal from a subject. From the signal, the time difference between two or more characteristic points in the signal may be computed. The time difference may correspond, for example, to the time for a pulse wave to travel a predetermined distance from the senor or probe to a reflection point and back to the sensor or probe. From this time difference, blood pressure measurements may be computed continuously or on a periodic basis. |
