Messages
Some waveforms may show a combination of shallow and deep breaths. If
the detection sensitivity percentage is set too high, the shallow breaths will
not be detected.
Decrease the detection sensitivity percentage until the
markers correctly identify each inspiration and expiration. See the
markers in the figures below.

Incorrect Detection
Correct Detection
Below is a list of all the messages which may be displayed in the RR parameter
window during respiration monitoring. What each of these messages mean as
well as action to take is included. These messages may appear in abbreviated
form if the parameter window is sized smaller due to the number of parameters
being monitored. The abbreviated form, if there is one, is shown in
parenthesis.
LEARNING
The monitor takes approximately 8 breaths to learn the patient’s
respiration pattern before displaying a respiration value. Learning
automatically occurs whenever respiration is turned on and when the
lead from which respiration is determined is switched.
APNEA
CHECK THE PATIENT. This is an alarm condition which requires
action. Breathing has not been detected for a predetermined period of
seconds. If necessary, the apnea limit can be changed. Refer to page 12-
8.
ARTIFACT
CHECK THE PATIENT. This is an alarm condition which requires
action. The monitor is unable to successfully determine respiration. If
it is determined that patient condition is not the cause, it may be
necessary to reprep the patient’s skin and change the electrodes to
resume monitoring of respiration.
