2. INTENDED USE
INTENDED USE
Full Indications for Use and Contraindications may be found in the 740 SELECT User
Manual, Zoe Medical PN 21-22-0316.
The 740 SELECT monitor facilitates the monitoring of:
ECG and heart rate (HR) with the ECG option for adult and pediatric patients;
Impedance pneumography to detect respiration rate (RR) or absence of respiratory effort
with the ECG option for adult, adolescent, child and infant patients.
The 740 SELECT monitor is a prescription device intended to be used by healthcare professionals
in all areas of a healthcare facility.
OVERVIEW OF HEART RATE MONITORING
ECG Monitoring works through the sensing the electrical signals generated by the electrical
activity of the heart as it beats. These signals are acquired from chest electrodes, and the 740
SELECT monitor amplifies the signals so they can be displayed on the screen. The patient’s heart
rate (HR) is calculated and continuously updated based on running average of the R to R
intervals between each QRS complex.
The ECG and HR monitoring capabilities of the 740 SELECT monitor include:
3-wire cable monitoring capabilities
Calculating the average heart rate (HR) in beats per minute
Detecting asystole and ventricular fibrillation
Pacer pulse detection
Generating an audible pulse tone for each detected beat

INTENDED USE AND INTRODUCTION 740 SELECT
21-22-0335 Rev D Page 9 of 40
OVERVIEW OF RESPIRATION RATE MONITORING
Respiration (Resp) monitoring works by measuring the impedance between the LL and RA
electrodes (or the R and F electrodes for IEC lead designations). The impedance changes as the
patient's chest expands and contracts during the breath cycle. To measure the changes in
impedance, the 740 SELECT monitor passes a very small, high-frequency current between the
electrodes. This current is too small to cause any harm to the patient or any interference with
ECG monitoring
The Respiration monitoring capabilities of the 740 SELECT monitor include:
Calculating the average Respiration Rate (RR) in respirations per minute
Displaying the Respiration waveform continuously
The same electrodes are used for both ECG and Respiration monitoring.
Note: A 740 SELECT monitor configured with capnography modules are also able to calculate
RR from the CO2waveform. In this case the Resp/RR feature from ECG is disabled.
Refer to User Manual Addendum - ETCO2Parameter, Zoe Medical PN 21-22-0333 for more
information.
PEDIATRIC CONSIDERATIONS
Cardiogenic artifact (heart rate pulsations that appear as "breaths" in the respiration signal) can
be quite pronounced in Pediatric patients. This can cause the respiration rate to be artificially high
(approaching the heart rate). To reduce cardiogenic artifact, move the White RA electrode (AHA
lead designation) or the Red R electrode (IEC lead designation) from the right clavicle down to
the right mid-clavical line, 4th intercostal space.

3. ECG MONITORING
Note: The following Warnings and Cautions are directed toward the ECG monitoring function.
Additional Warnings and Cautions for the 740 SELECT monitor are found in the 740 SELECT
User Manual, Zoe Medical PN 21-22-0316.
WARNINGS
Warning:The monitor is not intended for use in the following cases:
Apnea monitoring
In an MRI environment
Applications requiring automated arrhythmia detection
Applications requiring diagnostic-quality ECG
Warning: –DEFIBRILLATION. To avoid the possibility of serious injury or death during
patient defibrillation, do not come into contact with patient monitor or patient cables.
Additionally, proper placement of defibrillator paddles in relation to the ECG electrodes is
required to minimize harm to the patient. Only use accessories approved by Zoe Medical for
use with the monitor.
Warning: PACEMAKER PATIENTS. Rate meters may continue to count the pacemaker rate
during occurrences of cardiac arrest or some arrhythmias. Do not rely entirely upon heart rate
meter alarms. Keep pacemaker patients under close surveillance. See the Technical Data
chapter for disclosure of the pacemaker pulse rejection capability of this instrument.
Warning: PACEMAKER PATIENTS. When Analyze Pacers is disabled, the Heart Rate may
continue to count the pacemaker rate during occurrences of cardiac arrest. Keep pacemaker
patients under close surveillance and do not rely entirely upon Heart Rate alarms.
Warning: ELECTROSURGERY. The monitor is suitable for use in the presence of
electrosurgical (ESU) equipment. The following precautions should be taken:
To minimize the risk of patient burns, only use ESU equipment that monitors the
impedance of the ESU return wires.
Users should be properly trained in the operation of the ESU equipment.
Keep patient-applied cables (e.g., ECG lead wires) off of earth ground and away from the
ESU knife and return wires to prevent burns to measurement sites.
To prevent burns to the patient in the event of a defective neutral ECG electrode of the
device, it is necessary to place ECG electrodes far from the neutral electrode, and as
equidistant as possible from the blade-neutral axis of the surgical patient monitor.
When activating the ESU device, the ECG signals may be distorted or may disappear, and
Lead Fail or Noise alarms might be present. The signal should return once the ESU
activation stops.
When activating the device, using the SpO2 parameter as the heart rate source rather than
the ECG parameter to determine heart rate may be clinically preferred.
Only use accessories approved by Zoe Medical for use with the monitor.
Warning: ARRHYTHMIA PATIENTS. The monitor is designed to operate in the presence of
cardiac arrhythmias. However, the heart rate meter may be adversely affected in some
cases.
