0 to 300 mmHg

Systolic Range

60 to 250 mmHg

Diastolic Range

30 to 160 mmHg

Blood Pressure Determination Time

Typical: 15 seconds

Mean Arterial Pressure Range

40 to 190 mmHg

Pulse Rate Range
(using SpO

2

determination)

25 to 240 bpm

Pulse Rate Range
(using Blood Pressure determination)

35 to 199 bpm

Pulse Rate Accuracy (using SpO

2

determination)

Without Motion: 25 to 240 bpm ± 3 digits
