ABOUT END-TIDAL CO2 (EtCO2) MONITORING
The EtCO2 monitor is a capnometric device that uses non-dispersive infrared spectroscopy to
continuously measure the amount of CO2 during each breath and report the amount present at the
end of exhalation (EtCO2). The sample is obtained by side stream method and can be used with
intubated or nonintubated patients. Respiration rate is also measured and displayed in breaths per
minute.
Indications
EtCO2 monitoring is indicated for detection of trends in the level of expired CO2. It is used for
monitoring breathing efficacy and treatment effectiveness in acute cardiopulmonary care, for example,
to determine if adequate compressions are being performed during CPR or to rapidly detect whether
an endotracheal tube has been placed successfully. It is intended for use on adult and pediatric
patients.
Contraindications
None known.
ABOUT INVASIVE PRESSURE (IP) MONITORING
Invasive monitoring is intended for use in patients that require continuous monitoring of physiological
pressures in order to rapidly assess changes in patient condition and/or the patient’s response to
therapy. It may also be used to aid in medical diagnosis determination.
Indications
The LIFEPAK 12 invasive pressure monitor is indicated for use in measuring arterial, venous,
intracranial and other physiological pressures using an invasive catheter system with a compatible
transducer. It may be used on the adult or pediatric patient.
Contraindications
None known.
ABOUT VITAL SIGN AND ST MONITORING
The vital sign and ST monitoring features of the LIFEPAK 12 defibrillator/monitor provide
documentation of patient’s vital signs and ST segment measurements over 8 hours. All active vital
sign parameters and ST measurements can be displayed graphically for up to 8 hours. ST segment
measurement is initiated with a 12-lead ECG and is derived from the GE Medical systems 12SL
™
ECG analysis program.
ABOUT ECG MONITORING
The ECG (electrocardiogram) is a recording of the electrical activity of the heart. ECG monitoring
allows for identification and interpretation of cardiac rhythms or dysrhythmias and calculation of heart
rate. The ECG is obtained by placing either electrodes or paddles on the patient and allows the heart’s
electrical activity to be monitored and recorded.
