implement treatment strategies accordingly. In addition, the prehospital 12-lead ECG provides a
baseline for serial ECG evaluations. For further information, refer to the booklet, Prehospital 12-Lead
ECG: What You Should Know.
Indications
The 12-lead electrocardiogram is used to identify, diagnose and treat patients with cardiac disorders
and is useful in the early detection and prompt treatment of patients with acute myocardial infarction.
Contraindications
None known.
ABOUT SPO2 MONITORING
A pulse oximeter is a noninvasive device that checks the saturation of oxygen in arterial blood (SpO2).
The pulse oximeter uses an optical sensor that directs light through the patient’s finger and then
measures the received light with a detector. This received light is translated into a saturation
percentage and is displayed as an SpO2 reading.
Indications
Pulse Oximetry is indicated for use in any patient who is at risk of developing hypoxemia.
Contraindications
None known.
ABOUT NIBP MONITORING
The LIFEPAK 12 NIBP monitor measures the blood pressure of the adult or pediatric patient. The
monitor automatically inflates an occluding cuff and, using the oscillometric measurement technique,
determines systolic, diastolic, mean arterial pressures, and pulse rate. The measurement can be
initiated manually or set to recur at a predetermined interval.
Blood pressure measurements determined with this device are equivalent to those obtained by a
trained observer using the cuff/stethoscope auscultation method, within the limits prescribed by the
American National Standard, Electronic or automated sphygmomanometers (AAMI SP-10).
When a patient is experiencing arrhythmias during a measurement, the accuracy of the pulse
determination may be affected or the time needed to complete a measurement may be extended. In
shock conditions, the low amplitude of blood pressure waveforms makes it difficult for the monitor to
accurately determine the systolic and diastolic pressures. The device automatically deflates if a blood
pressure measurement cannot be obtained in 120 seconds.
Indications
Noninvasive blood pressure is indicated for detection in trends of hypertension or hypotension. These
include patient conditions indicated by abnormalities in various physiologic parameters such as shock,
evaluation of perfusion during dysrhythmias, major fluid shifts, evaluation of response to fluid therapy,
and titration of vasoactive and cardiotonic drugs. Noninvasive blood pressure monitoring may be
useful during ECG monitoring or for post-defibrillation recovery analysis.
Contraindications
None known.
