Abstract
Embodiments relate to devices, systems and methods of assisting blood flow return to the heart from a limb for fluid responsiveness and limb warming. The device comprising a wearable garment (115) and a compression apparatus (110) embedded in the garment (115) for applying an external compression according to a compression sequence to a muscle of a limb of a user based on real-time measurements during surgery.
Claims21
A method comprising:
- sensing, by a cardiac cycle sensor, real-time measurements regarding a cardiac cycle having a diastolic phase and systolic phase of a user;
- sensing, by a muscle activity sensor, real-time measurements of muscle contractions in a limb of the user;
- applying compressions, by a compression apparatus, to a muscle in the limb of the user for a desired period of time;
- and
- controlling the compression, by a processor coupled to the compression apparatus, according to a compression sequence, based on the real-time measurements of the cardiac cycle of the user and the real-time measurements of the muscle contractions such that a passive limb raise is simulated and fluid is returned to a central circulation.

A method for warming a body temperature of a user, comprising:
- sensing, by a temperature sensor, real-time measurements regarding the user's body temperature;
- sensing, by a cardiac cycle sensor, real-time measurements regarding a cardiac cycle having a diastolic phase and systolic phase of the user;
- sensing, by a muscle activity sensor, real-time measurements of muscle contractions in a limb of the user;
- warming the limb of the user by a warming apparatus;
- applying compression, by a compression apparatus, to a muscle in the limb of the user;
- and
- controlling the compression, by a processor coupled to the compression apparatus, according to a compression sequence, based on the real-time measurements of the cardiac cycle of the user and the real-time measurements of the muscle contractions to increase circulation of the user's warmed body fluid.
