Why the extras matter
Innovo lists an improved LED and sensor that can measure SpO2 and pulse rate even at low blood perfusion, such as with cold fingers. The plethysmograph (a pulse waveform) and the perfusion index show the signal strength, so you can tell if a reading is trustworthy or should be repeated.
Features and use
The iP900AP adds an audible alarm, pulse beeps and adjustable display brightness. It's aimed at home use, climbers, skiers, cyclists and pilots. Stay still during the measurement. It includes 2 AAA batteries and a lanyard. It gives useful information, but it doesn't replace medical advice.
