The delay due to the pulse oximeter equipment processing and averaging is

, the alarm
condition delay. The interval
t
3 -
t
2
, the alarm signal generation delay, is attributed to the alarm
system strategy and the communication time to the alarm signal generation device or distributed
alarm system (e.g. patient monitor or central station). Thus, the overall alarm system delay time is
