Not required; however, device
allows user calibration of offset
Notes:
• Automatic partial pressure compensation for barometric and airway pressure changes.
• Recommended interval for changing oxygen sensor is one year. However, sensor may
last longer. During user calibration of the sensor, the VT MOBILE can detect if the
sensor needs to be replaced.
