What is it indicated for?

The Vital Sign Monitoring Sensor (Model XK300) is intended to measure heart rate and respiration rate in adult patients

in a general care hospital environment including nursing homes. The Vital Sign Monitoring Sensor can be used for home

healthcare for data collection to inform patient care but not to acutely treat a patient. XK300 monitors presence or absence

of a patient in detection area of within 7 meters. The XK30 also monitors the length of continuous patient motion or

absence of patient motion.

Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
