ECG and Heart Rate Monitoring
3. ECG and Heart Rate Monitoring
3.1. Overview of ECG and 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 PPM3 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 Nightingale PPM3 include:
•
Displaying up to three leads of ECG continuously
•
3-wire cable with lead II monitoring
•
5-wire cable with leads I, II, III, V, AVL, AVR, and AVF.
•
Calculating the average heart rate (HR) in beats per minute (based the top
displayed ECG lead, or Lead II if no ECG lead is displayed)
•
Detecting asystole and ventricular fibrillation (based on heart rate lead)
•
Pacer pulse detection (performed on Lead II)
•
Generating an audible pulse tone for each detected beat
The Nightingale PPM3 is suitable for use in the presence of electrosurgical (ESU)
equipment.
WARNING
– ELECTROSURGERY. Consult the safety instructions at
the front of this manual before using electrosurgical equipment.
3.2. Getting Started with ECG on the PPM3
To begin monitoring ECG, use the following procedure:
1. Select and prepare the electrodes.
We recommend using pregelled, Ag/AgCl disposable electrodes. Depending
on the situation, you may want to use either the short-term (foam-backed) or
