1. A method comprising:
receiving, by a processor, a first set of sensor data from a first sensor positioned on the epidermis of a patient in a first location and in communication with the processor, wherein the patient is being monitored to determine a level of work expended by the patient to breathe;
receiving, by the processor, a second set of sensor data from a second sensor positioned on the epidermis of the patient in a second location, the second sensor being in communication with the processor;
determining, by the processor, a phase difference between the first and second sets of sensor data;
determining, by the processor, a degree of respiratory effort exhibited by the patient over a time period based on a determined phase difference between the first and second sets of sensor data;
determining, by the processor, a change in the level of work expended by the patient to breathe over the time period responsively to the determined degree of respiratory effort exhibited by the patient over the time period; and
communicating, by the processor, the change in the level of work expended by the patient to breathe over the time period to a display device.
