What should you do first when preparing to clean an ECG machine

What is power down and unplug the machine?

100

Turning off nearby devices may fix this artifact type

What is eliminating electrical interferences?

100

This is the setting for standard gain

What is 10mm/mV

100

How many small boxes make up one big box?

What is 5?

100

This method is used on both regular and irregular rhythms

What is the 6 second method?

200

What should be used when cleaning the external surfaces on an ECG machine

What is a soft cloth dampened with a mild detergent?

200

This artifact appears when there is a break in the baseline or a lead that is not recording

What is an interrupted baseline?

200

These are used to attach to the skin to detect the heart's electrical signals

What are electrodes?

200

What does one small box on the ECG paper represent in terms of time?

What is 0.04 seconds?

200

This method involves counting the number of small boxes between 2 consecutive P waves or 2 consecutive R waves before dividing

What is the Small Box Method (1500 Method) 

300

What areas of an ECG machine require more attention?

What are high touch areas? (control buttons, display screens, handles)

300

This artifact happens when the patient's muscles move during an ECG

What is a somatic tremor?

300

This is the standard setting for paper speed

What is 25mm/sec

300

What is the time duration represented by 5 large boxes?

What is 1 second?

300

This method involves counting the number of big boxes between 2 consecutive waves or 2 consecutive R waves before dividing.

What is the Big Box Method (300 Method) 

400

What should you ensure not enter vents, plugs or jacks?

What is liquid?

400

Poor electrode contact, loose skin, or patient breathing deeply can cause this artifact that looks like the entire tracing is slowly drifting.

What is a wandering baseline?

400

What do you increase on an ECG machine when dealing with faster heart waves

What is Speed

400

How many seconds are represented by 4 small boxes?

What is .16 seconds

400

Which of the methods would be used on a Sinus Dysrhythmia?

What is the 6 Second Method 

500

What does proper maintenance of an ECG ensure?

What is machine functions accurately and delivers precise recordings?

500

When skin oils or lotions prevent electrodes from sticking, this step is essential to ensuring a clean tracing

What is re-cleaning the skin?

500

What setting should you change on an ECG machine when dealing with short and low waves

What is Gain?

500

How many big boxes are in 2 seconds?

What is 10?

500

This method involves counting the number of P waves or R waves and multiply by 10 to get the heart rate for one minute 

What is the 6 Second Method?
