  • Page 15 Do not pull or stretch patient cables as this could result in mechanical and/or electrical failures. Lead wires should be stored after forming them into a loose loop.  The WAM PC will only work with the Welch Allyn UTK receiving devices that is equipped with the appropriate software. ...
  • Page 16 If electrode is not properly connected to the patient, or one or more of the patient cable lead wires is damaged, the WAM PC will indicate a lead fault. If this occurs during waveform acquisition, the WAM PC may not be able to collect enough good quality waveforms within 60 seconds and the acquisition will have to be repeated after fixing the lead fault condition.

    CARE AND MAINTENANCE Precautions • Turn off the device before inspecting or cleaning. • Do not immerse the device in water. • Do not use organic solvents, ammonia-based solutions, or abrasive cleaning agents which may damage equipment surfaces. Inspection 1. Inspect your equipment daily prior to operation. If you notice anything that requires repair, contact an authorized service person to make the repairs.

  • Page 19: Introduction

    ECGs from patients. WAM PC Description The WAM PC is a resting ECG acquisition module with memory. It does not need to be connected to a full-featured electrocardiograph while it records ECG waveforms from a patient. It is simply attached to a patient and used to acquire 60 seconds of raw ECG waveforms into its memory.

    6.7 oz. (190 g) with battery 4.45 x 4.25 x 1.1” (11.3 x 10.8 x 2.79 cm) Dimensions 1 AA alkaline battery typically powers WAM PC for acquisition of Battery Life 250 resting ECGs *Specifications subject to change without notice.

  • Page 21: Using The Wam Pc

    This will cause the unit to lose power and turn off if it wasn’t already off. Tilt the WAM PC slightly so the battery slides out. Dispose of the old battery according to local policies and ordinances. Slide a fresh AA battery into the WAM PC according to the diagram on the back of the module (negative terminal goes in first).

  • Page 22: Preparing The Patient's Skin

    RECOMMENDED ELECTRODES Low-impedance connections to the patient’s skin will minimize noise in the ECG waveforms. High quality silver-silver chloride (Ag/AgCl) electrodes similar to those provided by Welch Allyn are highly recommended. TIP: Electrodes should be stored in air-tight containers to minimize exposure to air. When left exposed to the air, electrodes will dry out quickly, lose their adhesion, and produce noisy waveforms.

    1. Ensure the WAM PC has a battery. Have a fresh battery available in case the current one starts to give the Battery Low signal (3 short beeps every 15 seconds). See Replacing the Battery. 2. If unsure that the WAM PC is ready to acquire new ECG waveforms, power it on and observe the LED: a.
  • Page 26 Tell the patient to remain still and relaxed until it is finished. c. If the WAM PC should start giving 2 audible ticks per second, it means one or more of the electrodes has stopped making good contact with the patient’s skin. Check the electrodes and lead wires and fix as necessary.
