VITAL SIGN MONITOR FOR CUFFLESSLY MEASURING BLOOD PRESSURE WITHOUT USING AN EXTERNAL CALIBRATION
摘要
<p>The invention provides a method for measuring a patient's blood pressure featuring the following steps: 1) measuring a first time-dependent optical signal with a first optical sensor; 2) measuring a second time-dependent optical signal with a second optical sensor; 3) measuring a time-dependent electrical signal with an electrical sensor; 4) estimating the patient's arterial properties using either the first or second time-dependent optical signal; 5) determining a pulse transit time (PTT) from the time-dependent electrical signal and at least one of the first and second time-dependent optical signals; and 6) calculating a blood pressure value using a mathematical model that includes the PTT and the patient's arterial properties.</p>
