Respiration; Cardiovascular Artifact Detection (Cva); Using Co2 As The Resp Source - Escort Prism 20401 Reference Manual

Respiration

Respiratory monitoring may be done either by impedance pneumography via ECG leads of RA
(right arm) and LA (left arm) or through ETCO2. Location of ECG electrodes may need to be
altered to allow correct count of RESPS. Review lead placement charts for respiratory
monitoring. The monitor can be set to look via an AUTO mode for source of RESPS.
To monitor a patient's Respiration:
1. Open the RESP SETUP menu by pressing the softkey next to the RESP label.

LIM

2. Press the ALM ON softkey if respiratory alarms are to be activated.
3. Press the ALM LIM softkey to adjust values for current respiratory high/low alarms. Apnea
delay alarms can be set as needed.
4. Press the SIZE softkey to allow increase or decrease of RESP waveform. Adjusting
"sensitivity" may improve count accuracy.
5. If this parameter is no longer desired or patient is not a good candidate for respiratory count
via impedance pneumography, press the MORE softkey, then press the RESP OFF softkey.

Cardiovascular Artifact Detection (CVA)

MDE's cardiovascular artifact detection gives you the ability to determine whether or not a
patient's (typically a neonate's) heart beat is being interpreted as an inspiration. When ECG leads
are used as a RESP source, artifact can occur because of the relative size of a neonate's heart, and
the close proximity of the leads to the movement created by the heart. To alert personnel to this
possible occurrence, CVA detection looks for any period when 8 out of 10 RESP's appear to
occur simultaneous with a heartbeat. If this happens, the monitor will alarm when CVA is ON.

Using CO2 as the RESP Source

When you monitor ETCO2 (CO2) in addition to ECG and your RESP source (RR) is set to
AUTO, the monitor will choose CO2 as the primary RESP source. This can be overridden if
desired in the RESP setup menu.
