Respiration
Overview
The respiration function detects and displays a waveform that:
• represents each breath.
• provides the respiration rate.
• detects and rejects cardiovascular artifact.
• initiates alarms when limits are violated for either the respiration rate or
apnea.
Changes in thoracic impedance during patient inspiration and expiration provide
respiration data through the use of the ECG cable. Lead selection for respiration is
independent of lead selection for ECG, even though both receive data from the
same electrodes.
Varitrend 3, an optional feature in some modules, generates a graph that plots
heart rate, SpO
2
, and respiratory rates. You can view this plot on the monitor or
print it on a system or bedside printer.
The Event Trend feature of Varitrend 3 enables you to screen for apparent life
threatening events such as bradycardia, with desaturation, or apnea accompanied
by a change in heart rate. This feature plots bradycardia, tachycardia, apnea and
desaturation trends for viewing and printing. A 24-hour trend of events is
maintained and up to 48 events are stored in memory. Refer to Configuring
Varitrend 3 Graphs on page 12-10 for more details.

• You can define your own default settings for alarm limits and the
display configuration. Refer to Setting User-Defined Default
Values on page 7-7 for further details.
