## Indications for use
The 750C monitor is intended to continuously calculate and display the following physiological vital signs: end tidal carbon dioxide, respiration rate, capnograph waveform, functional arterial oxygen saturation, pulse rate, plethysmograph waveform and an optional non-invasive blood pressure measurement of systolicdiastolic, mean arterial pressures along with pulse rate derived from a NIBP pressure waveform. The 750C is intended for monitoring of adult, pediatric and neonatal patients in the care of health care professionals.
