Ischemic Conditioning in STEMI Patients

"A manual sphygmomanometer will be inflated over the brachial artery of the participants' arm that does not have an intravenous catheter actively infusing medications. If both arms are in use, then the participant's non-dominant arm will be used.~* The sphygmomanometer will be inflated to a pressure at least 20 mmHg greater than the participants' last recorded systolic blood pressure.~* The sphygmomanometer will be inflated for 5 minutes then rapidly deflated for 5 minutes, thereby concluding one iteration.~* Five (5) total iterations constitute the treatment.~* The left arm will be preferentially used instead of the right arm, unless the left arm is receiving medication administration."
