Using the Electrocardiograph Safely

Before using or servicing the electrocardiograph, you must read and understand the following safety-related information.

General Warnings

The following warning statements apply to electrocardiograph use in general. Warning statements that apply specifically to particular procedures, such as connecting the patient cable or performing an ECG test, appear in the corresponding sections of the manual.

Warning statements indicate conditions or practices that could lead to illness, injury, or death.

Warnings Related to the Environment

WARNING To ensure patient and device safety, leave 5 feet (1.5 meters) of

open area around the patient.

WARNING To avoid a possible explosion, do not use the electrocardiograph in the presence of flammable anesthetics.

WARNING When transporting the electrocardiograph on a cart, tuck the patient cable away from the wheels so that it does not present a hazard.

Warnings Related to Accessories and Other Equipment

WARNING For operator and patient safety, peripheral equipment and

accessories that can come in direct patient contact must be in compliance with all appropriate safety, EMC, and regulatory requirements. See “EMC Guidance

and Manufacturer’s Declarations” on page 69.

WARNING All signal input and output (I/O) connectors are intended for connection of only devices complying with IEC 60601-1, or other IEC standards (for example, IEC 60950), as appropriate to the device. Connecting additional devices to the electrocardiograph may increase chassis or patient leakage currents. To maintain operator and patient safety, consider the requirements of IEC 60601-1-1. Measure the leakage currents to confirm that no electric shock hazard exists.

WARNING The electrocardiograph has not been designed for use with highfrequency (HF) surgical equipment and does not protect against hazards to the patient.

Directions for Use Chapter 1 Introduction 15

Warnings Related to Using the Electrocardiograph

WARNING This device captures and presents data reflecting a patient’s

physiological condition. When reviewed by a trained physician or clinician, this data can be useful in determining a diagnosis. However, the data should not be used as a sole means for determining a patient’s diagnosis.

WARNING To avoid serious injury or death, take these precautions during patient defibrillation:

• Avoid contact with the electrocardiograph, patient cable, and patient.

• Verify that the patient leads are properly connected. See “Connecting the

Patient Cable” on page 20.

• Place defibrillator paddles properly in relation to electrodes.

• After defibrillation, pull each patient lead out of the patient cable and inspect the tips for charring (black carbon marks). If there is any charring, the patient cable and individual leads must be replaced. If there is no charring, fully reinsert the leads into the patient cable. (Charring can occur only if a lead is not fully inserted into the patient cable before defibrillation.)

WARNING To prevent the spread of infection, take these precautions:

• Dispose of single-use components (for example, electrodes) after using them once.

• Regularly clean and disinfect all components that come in contact with patients. See “Cleaning the Equipment” on page 52.

• Avoid ECG testing for patients with open, infectious sores.

WARNING Avoid positioning any leads or cables so that they could easily trip someone or become wrapped around a patient’s neck.

WARNING Satisfactory maintenance procedures must be implemented, or equipment failure and health hazards may result.

WARNING Only qualified service personnel should attempt to repair the electrocardiograph. In case of a malfunction, call Technical Support and precisely describe the problem. For phone numbers, see page ii.

mechanical or electrical failures. Form the patient cable into a loose loop before storing.

Caution Avoid positioning the patient cable where it might get pinched or stepped on. If the cable’s impedance is altered, measurements might no longer be accurate, and repair might be necessary.

Caution Using the equipotential terminal for anything but grounding purposes may contribute to damage of the device.

Caution Use only parts and accessories supplied with the device and available through Welch Allyn. The use of accessories other than those specified may result in degraded performance of this device.

Caution Portable and mobile RF communications equipment can affect the performance of the electrocardiograph.

Caution The electrocardiograph meets the Class A requirements of IEC 606011-2:2000 regarding incidental emission of radio frequency interference. As such it is suitable for use in commercial grade electrical environments. If the electrocardiograph is used in residential grade electrical environments and you experience incidental interference with other equipment that uses radio frequency signals to operate, minimize the interference as described under

“EMC Guidance and Manufacturer’s Declarations” on page 69.

Caution Other medical equipment—including but not limited to defibrillators, ultrasound machines, pacemakers, and other stimulators—may be used simultaneously with the electrocardiograph. However, such devices may disturb the electrocardiograph signal.

Inspecting the Electrocardiograph

1. Look for obvious signs of shipping damage. If you find any damage, contact Technical Support. For phone numbers, see page ii.

2. Verify that you have received all appropriate options and accessories. See “Options” on page 4 and “Accessories” on page 5.

Connecting the Patient Cable

WARNING Conductive parts of the patient cable, electrodes and associated connections of Type CF applied parts, including the neutral conductor of the patient cable and electrode, should not come into contact with other conductive parts, including earth ground.

WARNING To avoid injury to the patient or damage to the device, never plug patient leads into any other device or wall outlet.

1. Insert all leads into their proper positions, as labeled on the connectors.

Insert connectors fully so that no part of the metal ring remains exposed. For example, see Figure 12. (To see the whole patient cable with all leads inserted, see Figure 11 on page 11.)

WARNING Failure to insert all connectors fully may result in a loss of energy being delivered to the patient during defibrillation and damage to the patient cable itself. For other warnings related to defibrillation, see page 15.

2. Plug the patient cable into the port on the front of the electrocardiograph. See Figure 13.

Powering the Electrocardiograph

The electrocardiograph can run on AC or battery power.

WARNING To ensure that electrical safety is maintained when using AC power, the device must be plugged into a hospital-grade outlet.

WARNING Where the integrity of external protective earth conductor arrangement is in doubt, use battery power.

Caution Medical electrical equipment needs special precautions regarding EMC and must be installed and used according to the information provided in “EMC

Guidance and Manufacturer’s Declarations” on page 69.

To Connect to AC Power

Plug one end of the power cord into the electrocardiograph’s AC power inlet. Plug the other end into an AC outlet. The green LED on the keyboard lights up, indicating that power is connected. See Figure 17.

To Keep the Battery Charged

Leave the electrocardiograph connected to AC power whenever possible. Battery charge status is indicated on the screen by an icon: . When the charge gets low, the icon flashes. When the charge gets too low to operate, a warning message appears and the electrocardiograph beeps every 15 seconds for 1 minute, then it turns off.

For more, see “Recharging a Fully Discharged Battery” on page 54.
