Philips FM20 - QRS Volume; Delta ExtrTachy, Delta ExtrBrady; Tachy Clamp, Brady Clamp

QRS Volume
The QRS Volume setting defines the default volume of the QRS Tone. The QRS Tone is derived from
either the
MECG or Pulse from SpO2, depending on which is currently selected as the Alarm Source.
NOTE
This setting is accessible in this menu, but is actually a Monitor Setting, see “QRS Volume” on
page 58.
Delta ExtrTachy, Delta ExtrBrady
Extreme bradycardia and extreme tachycardia alarms are based on the Pulse limit alarms. Use the
Δ
ExtrTachy and Δ ExtrBrady setting to define the difference between the heart rate limit and the
extreme limit.
For example, if the Pulse
High Limit is 120 bpm, and the Δ ExtrTachy is 20 bpm, the resulting ***Tachy
(Pulse)
alarm would be generated if the Pulse is higher than 140 bpm (see graphic below).
NOTE
HR and Pulse share the same alarm limits. The Δ ExtrTachy and Δ ExtrBrady settings apply to the
currently selected alarm source, either
HR or Pulse.
Tachy Clamp, Brady Clamp
The Brady Clamp and Tachy Clamp setting allows you to configure a safety threshold for the extreme
bradycardia and tachycardia alarm limits.
For example, if the Pulse
Low Limit is 50 bpm, and the Δ ExtrBrady setting is 20 bpm (50 bpm - 20 bpm
= 30), with a
Brady Clamp set at 40, a ***Brady (Pulse) alarm would be generated if the Pulse is lower
than 40 bpm.
NOTE
HR and Pulse share the same alarm limits. The Tachy Clamp and Brady Clamp settings apply to the
currently selected alarm source, either
HR or Pulse.
