Pulse Rate Delay Alarm Management Feature

The oximeter also monitors pulse rate by determining the number of pleth waves
over unit time. With traditional alarm management, upper and lower alarm limits are
set for monitoring pulse rate. When the pulse rate fluctuates near an alarm limit, the
alarm sounds each time it violates an alarm limit. The Pulse Rate Delay feature allows
a period of threshold violation before the pulse rate alarm sounds. Thus, the Pulse
