EtCO

Indications for Use
The ZOLL M Series EtCO
2
option is indicated for the
continuous noninvasive monitoring of end tidal carbon
dioxide (EtCO
2
) and respiration rate in patients requiring
ventilator support, transport, or anesthesia. The M Series
EtCO
2
option with Respironics Novametrix technology
supports two methods for continuous measurement of
end tidal carbon dioxide (EtCO
2
) and respiration rate.
The first method uses the CAPNOSTAT 3 Mainstream
CO
2
Sensor attached to an airway adapter that connects
to an endotracheal tube, mask or disposable
mouthpiece.
The second method uses the LoFlo Sidestream CO
2
Module to monitor both non-intubated and intubated
patients using specially designed sampling cannulae and
airway adapters.
The M Series EtCO
2
option is designed to monitor adult,
pediatric, and neonatal patients.
The following substances can influence CO
2
measurements made with the CAPNOSTAT 3 Sensor:
• elevated oxygen levels
• nitrous oxide
• halogenated agents
The M Series EtCO
2
option allows the user to enable
high oxygen and/or nitrous oxide compensation.
Halogenated anesthetic agents alter CO
2
readings, but
the M Series unit will monitor CO
2
within specifications
when these agents are present at normal clinical levels.
The presence of Desflurane in the exhaled breath
beyond normal values (5-6%) may positively bias
measured carbon dioxide values by up to an additional
2-3 mmHg.
The M Series EtCO
2
option is intended for use only with
the ZOLL/Respironics Novametrix CAPNOSTAT 3
Mainstream CO
2
sensor and the LoFlo Sidestream CO
2
Module, mainstream airway adapters, nasal and nasal/
oral sampling cannulae, and sidestream on-airway
adapters.
Mainstream EtCO
2
Setup
There are several steps involved with mainstream
EtCO2 setup, as follows:
• Attaching the CAPNOSTAT 3 sensor cable.
• Selecting a mainstream airway adapter.
• Attaching the airway adapter to the CAPNOSTAT 3
sensor.
• Zeroing the mainstream sensor/airway adapter.
• Attaching the airway adapter to the airway circuit.
• Applying an airway adapter with mouthpiece.
Attaching the CAPNOSTAT 3 Sensor Cable
To attach the CAPNOSTAT 3 sensor cable, plug the
cable into the CO
2
connector at the back of the M Series
unit.
Note Effective with M Series software revision 38.35 and
M Series CCT software revision 57.50, the “0” and
“REF” cells on the sensor cable are no longer used.
However, they remain on the sensor cable for
backwards compatibility with earlier versions of the
software.
Selecting a Mainstream Airway Adapter
Select an airway adapter based on the patient's size, ET
tube diameter and monitoring situation. For more
information refer to the following table or contact ZOLL
Medical Corporation.
*SPU = Single Patient Use
Attaching the Airway Adapter to the
CAPNOSTAT 3 Sensor
Before attaching the airway adapter to the
CAPNOSTAT 3 sensor, verify that the airway adapter
windows are clean and dry. Clean or replace the adapter
if necessary.
CAUTION! The disposable (SPU) Pediatric/Adult and
the Neonatal/Pediatric airway adapters are
intended for single patient use. Do NOT
reuse or sterilize these adapters as system
performance will be compromised.
1. Attach the airway adapter to the CAPNOSTAT 3
sensor, as follows:
a. Align the arrow on the bottom of the airway adapter
with the arrow on the bottom of the CAPNOSTAT 3.
b. Press the sensor and airway adapter together until
they click.
2. If the unit displays the “CHECK CO2 ADAPTER”
message, follow steps a through c, or else go to
step 3.
a. Verify proper connection of the adapter to the
sensor.
b. Verify that the airway adapter windows are clean
and dry.
Airway Adapter Type ET Tube Diameter
