Working as a nurse in drug detox, most of the patients have extremely low blood pressures, of 70/50 and below, with high levels of methadone etc. Taking blood pressures is extremely challenging with the population particularly with damaged veins due to IV abuse. The EKO is one of the few devices that allows for accurate readings over time, and provides a better baseline for safe administration of medication before morning dosing! Thanks for making this! A lot of the older nurses use the wrist cuffs because the can't hear but with the Eko its made it an equal playing field and at the cost of an expensive cardiac stethoscope provides an affordable high quality hearing device!
