Monitoring blood distribution in a subject

A method of monitoring blood distribution in a subject, comprising:

• receiving Doppler ultrasound data representing a first arterial blood flow value at a first location and a second arterial blood flow value at a second location of the subject;
• performing a first comparison of the first arterial blood flow value and the second arterial blood flow value, wherein the first comparison comprises calculation of a ratio between the first arterial blood flow value and the second arterial blood flow value, wherein the ratio is associated with the blood distribution in the subject;
• performing a second comparison of the ratio to a first threshold associated with hypovolemia and to a second threshold associated with hypervolemia;
• detecting the hypovolemia when the ratio is greater than the first threshold;
• detecting the hypervolemia when the ratio is less than the second threshold;
• and
• generating an output indicative of the hypovolemia when the ratio is greater than the first threshold and indicative of the hypervolemia when the ratio is less than the second threshold.

A non-transitory computer readable medium comprising a plurality of instructions stored thereon, wherein, when executed by a processor, the plurality of instructions is configured to cause the processor to:

• receive Doppler ultrasound data representing a first arterial blood flow value at a first location and a second arterial blood flow value at a second location of a subject;
• perform a first comparison of the first arterial blood flow value and the second arterial blood flow value, wherein the first comparison comprises calculation of a ratio between the first arterial blood flow value and the second arterial blood flow value, wherein the ratio is associated with a blood distribution in the subject;
• perform a second comparison of the ratio to a first threshold associated with hypovolemia and to a second threshold associated with hypervolemia;
• detect the hypovolemia when the ratio is greater than the first threshold;
• detect the hypervolemia in the subject when the ratio is less than the second threshold;
• and
• generate an output indicative of the hypovolemia when the ratio is greater than the first threshold and indicative of the hypervolemia when the ratio is less than the second threshold.
