Actually I bought this pulse oximeter for home use. Meanwhile, I use it as well on a regular basis in the emergency service. The device is not tested TÜV, but often refuse confused or shocked patients, to carry the pulse oximeter of the defibrillator, since these enable the always loud warning "Schokelektroden connect" spends! Since the small Pulsoxi acts equal less threatening!
When direct consumption with the pulse oximeter of the defibrillator in an ambulance (Fred Schiller) there was little variation.
