Abstract
Systems are provided for determining the pulse wave velocity of blood flowing within a blood vessel. Disclosed systems may include first and second sensors at spaced apart locations in the blood vessel. The first sensor, in a first position, x1, in the vessel, r is configured to obtain a first area measurement, m1, of the vessel. The second sensor, in a second position, x2, in the vessel, is configured to obtain a second area measurement, m2, of the vessel. Disclosed systems may also include a processor configured to determine the pulse wave velocity of the vessel based on the first and second area measurements.
Claims22
A system for determining the pulse wave velocity of a blood vessel, comprising:
- a first sensor in a first position, x1, in the vessel, the first sensor configured to obtain a first area measurement, m1, of the vessel;
- a second sensor in a second position, x2, in the vessel, the second sensor configured to obtain a second area measurement, m2, of the vessel;
- and
- a processor configured to determine the pulse wave velocity of the vessel based on the first and second area measurements.
(canceled)
A method for determining the pulse wave velocity of a blood vessel comprising:
- obtaining a first area measurement, m1, of the vessel from a first sensor in a first position, x1, in the vessel;
- obtaining a second area measurement, m2, of the vessel from a second sensor in a second position, x2, in the vessel;
- determining the pulse wave velocity of the vessel based on the obtained first and second area measurements.
A system for determining the pulse wave velocity of a blood vessel, comprising:
- a first sensor in a first position, x1, on the skin overlying the vessel, the first sensor configured to obtain a first measurement, m1, of the vessel;
- a second sensor in a second position, x2, on the skin overlying the vessel, the second sensor configured to obtain a second measurement, m2, of the vessel;
- wherein the distance between the first position and the second position is determined by the equation Δx=x2−x1, and
- a processor configured to determine the pulse wave velocity of the vessel based on the first and second area measurements.
