Abstract
A system and method for measuring blood pressure. In some embodiments, a system includes a speckleplethysmography sensor and a processing circuit. The system may be configured: to perform, using the speckleplethysmography sensor, blood flow measurements of a subject, and measurements of cuff pressure of a cuff worn by the subject, while the cuff pressure varies; and to calculate, from the blood flow measurements and the cuff pressure measurements, a first blood pressure.
Claims20
A system, comprising:
- a speckleplethysmography sensor;
- and
- a processing circuit,
- the system being configured:
- to perform, using the speckleplethysmography sensor, blood flow measurements of a subject, and measurements of cuff pressure of a cuff worn by the subject, while the cuff pressure varies;
- and
- to calculate, from the blood flow measurements and the cuff pressure measurements, a first blood pressure.

A method, comprising:
- measuring a first blood pressure,
- the measuring of the first blood pressure comprising:
- varying a cuff pressure of a cuff on an appendage of a subject;
- generating a speckleplethysmography signal from a speckleplethysmography sensor on the appendage;
- and
- determining the first blood pressure based on the speckleplethysmography signal and based on the cuff pressure.
