Abstract
A system and method for calibration a system of determining blood pressure based on pulse wave transit time.
Claims20
A method of calibrating a system for determining blood pressure based on pulse wave transit time comprising:
- initiating, by a gateway device, a calibration mode;
- establishing, by the gateway device, a first connection between the gateway device and a monitoring device mounted on a body of a patient;
- establishing, by the gateway device, a second connection between the gateway device and a digital sphygmomanometer;
- receiving, by the gateway device, first collected data from the monitor device, wherein the first collected data includes ECG raw data and PPG raw data;
- receiving, by the gateway device, second collected data from the digital sphygmomanometer, wherein the second collected data includes systolic/diastolic pressure information indicative of a blood pressure of the patient obtained using a cuff positioned on the patient's body;
- checking, by the gateway device, the first collected data and the second collected data for errors;
- packaging, by the gateway device, the first collected data and the second collected data with other data, wherein the other data includes at least a time stamp;
- calculating, by the gateway device, one or more calibration coefficients based on the first collected data, second collected data and the other data;
- and
- storing, by the gateway device, the one or more calibration coefficients in a memory operatively connected to the gateway device.

A method of generating a complex wave signature associated with a position of a monitor device on a patient's body comprises:
- receiving, at a gateway device in communication with a monitor device, patient information associated with the patient on which the monitor device is positioned;
- receiving, at the gateway device, position information indicating a current position of the monitor device on the patient's body;
- receiving, at the gateway device from the monitor device, ECG data associated with a heartbeat of the patient;
- determining, by the gateway device, whether the ECG data meets at least one designated criteria;
- generating, by the gateway device, the complex wave signature based on median values of the ECG data;
- and
- storing, by the gateway device, the complex wave signature in at least one memory operably connected to the gateway device.

A method of automatically determining a position of a monitor device on a patient's body comprises:
- receiving, by a gateway device in communication with the monitor device, a first complex wave signature associated with a first position and a second complex wave signature associated with a second position;
- receiving, by the gateway device from the monitor device, ECG data associated with a heartbeat of the patient;
- determining, by the gateway device, whether the ECG data meets at least one designated criteria;
- generating, by the gateway device, a current complex wave signature based on median values of the ECG data;
- comparing, by the gateway device, the current complex wave signature to the first complex wave signature and the second complex wave signature;
- and
- selecting, by the gateway device, one of the first position and the second position based on a relationship of one of the first complex wave signature and the second complex wave signature to the current complex wave signature.
