EKG Calibration and Interpretation Concepts

The video tutorial provides a comprehensive overview of EKG paper, focusing on its standards, calibration, and the significance of graph paper measurements. It explains the importance of deflections in EKG readings and details the standard paper speed and calibration requirements. The tutorial also covers the role of the calibration spike in ensuring accurate EKG interpretation.

What is the primary purpose of calibrating the EKG machine to the paper?

• To ensure the paper is the correct size

• To change the color of the grid lines

• To match the machine's settings with the paper for accurate readings

• To make the paper more durable

What are the dimensions of a big box on the EKG graph paper?

• 2 mm by 2 mm

• 5 mm by 5 mm

• 1 mm by 1 mm

• 10 mm by 10 mm

How many small boxes are contained within a big box on the EKG paper?

• 15

• 25

• 10

• 20

What does a deflection of 11 mm on the EKG paper represent in terms of molts?

• 0.5 molts

• 2.0 molts

• 0.8 molts

• 1.1 molts

What is the standard paper speed for EKG tracings?

• 10 mm/s

• 75 mm/s

• 25 mm/s

• 50 mm/s

Why is it important to maintain the standard paper speed of 25 mm/s?

• To save paper

• To ensure the EKG fits on one page

• To maintain consistency in interpretation rules

• To make the EKG look more detailed

What does a calibration spike indicate on an EKG tracing?

• The patient's heart rate

• The color of the grid lines

• The paper's thickness

• The paper speed and amplitude

How tall should the standard calibration spike be to indicate a 1 molt amplitude?

• 15 mm

• 20 mm

• 10 mm

• 5 mm

What happens if the calibration spike is not 10 mm tall?

• The paper speed is incorrect

• The EKG is more accurate

• The gain or amplitude standard has been changed

• The EKG is automatically invalid

What should you do if the EKG calibration does not match the standard settings?

• Adjust the grid lines

• Change the paper

• Reobtain the EKG with standard settings

• Ignore it and proceed
