a.
Motion for adults and pediatrics is defined as rubbing and tapping motions at 2 to 4 Hz at an amplitude of 1 to 2 cm and a non-
repetitive motion between 1 to 5 Hz at an amplitude of 2 to 3 cm in induced hypoxia studies in the range of 70-100% SpO

against a
laboratory co-oximeter and ECG monitor. This variation equals ± 1 standard deviation which encompasses 68% of the population.
b.
Motion for neonates is defined as foot motions at 2 to 4 Hz at an amplitude of 1 to 2 cm against a laboratory co-oximeter and ECG
monitor. This variation equals ± 1 standard deviation which encompasses 68% of the population.

Note: Any pulse rate above 239 will activate the pulse rate alarm, even if the
upper alarm limit is set above 239.
If the lower alarm limit is set to 25, a pulse rate of 25 will activate the pulse
rate alarm due to the limitation of the displayable numeric range.
