Methods, devices and systems to compute a vascular score for a user, comprising retrieving, from a measuring device, a pulse wave velocity (PWV) related datum of the user retrieving a chronological age datum of the user querying to return a quantile value, computing, using the retrieved chronological age, the returned quantile value and a predetermined law, a vascular score; and generating for display on the measuring device or on a user device, an indication associated with the vascular score.

Systems and methods for monitoring physiologic response to Valsalva maneuver (VM) are disclosed. An exemplary patient monitor may detect a natural incidence of a VM session occurred in an ambulatory setting using a heart sound (HS) signal sensed from the patient. The patient monitor may include a physiologic response analyzer to sense patient physiologic response during the detected VM session, and generate a cardiovascular or autonomic function indicator based on the sensed physiologic response to the VM. Using the physiologic response to the VM, the system may detect a target physiologic event using the sensed physiologic response to the VM.

A measurement apparatus includes a plurality of sensors wearable on different parts of a human body and a controller configured to acquire an output value of each of the sensors. The sensor each outputs an output value to calculate the same type of biological information by optical measurement, the controller selects either the sensor on the basis of each output value of the sensors, and determines a measured value of the biological information on the basis of an output values of the sensors selected.

In an embodiment, cross sectional image storage stores a cross sectional image group including multiple cross sectional images each of which is associated with time. Phase image storage stores a phase image group including multiple phase images each of which is associated with time. Blood flow information storage stores a blood flow information group including multiple blood flow information each of which is related to blood flow in a blood vessel of the living body and is associated with time. Display synchronously displays a cross sectional image included in the cross sectional image group and a phase image included in the phase image group using time associated with the cross sectional image and the phase image, and displays a blood flow image that expresses multiple blood flow information. The display performs the same change as the change to the cross sectional image, the phase image and the blood flow image.
