Claim 11:
12. A method for detecting a lung pulse in a patient, comprising:
obtaining, by an ultrasound probe, ultrasound imaging data representative of a lung of the patient;
generating, by a processor communicatively coupled to the ultrasound probe and using the ultrasound imaging data received from the ultrasound probe, an M-mode image including a pleural line of the lung, the M-mode image comprising a plurality of samples obtained along a scan line;
generating, by the processor, a difference image from the M-mode image, the difference image comprising a plurality of difference lines generated by subtracting adjacent samples of the M-mode image, each of the plurality of difference lines comprising a plurality of intensity values;
determining, by the processor, whether the difference image includes a periodic signal representative of a lung pulse, wherein the lung pulse comprises a movement of a pleural line corresponding to a heartbeat of the patient; and
outputting, to a display in communication with the processor, a graphical representation of detecting the lung pulse in response to determining that the difference image includes the periodic signal.
