Setting Up Tone Modulation; Setting The Qrs Volume - Philips Avalon FM20 Instructions For Use Manual

Alarm Delays
There is a delay between a physiological event at the measurement site and the corresponding alarm at
the monitor. This delay has two components:
• The general system delay time is the time between the occurrence of the physiological event and
when this event is represented by the displayed numerical values. This delay depends on the
algorithmic processing and the configured averaging time. The longer the averaging time
configured, the longer the time needed until the numerical values reflect the physiological event.
• The time between the displayed numerical values crossing an alarm limit and the alarm indication
on the monitor. This delay is the combination of the configured alarm delay time plus the general
system alarm signal delay time.

Setting Up Tone Modulation

If tone modulation is on, the QRS tone pitch lowers when the SpO
tone is derived from either heart rate (from MECG) or pulse (from SpO
currently displayed (see "Priority for Maternal Heart / Pulse Rate" on page 155).
NOTE
Pulse from Toco MP does not provide a QRS tone.
