How to measure pressure by a mechanical tonometer

To determine the pressure, you can use automatic or mechanical tonometer. To obtain reliable results, you should not only learn how to use a tonometer, but also to properly prepare for the measuring procedure. Automatic tonometer to use simply. It is much harder to measure the pressure by a mechanical tonometer.

You will need

• - stethoscope;
• - tonometer.

Instruction

1. Before measuring the pressure, do not smoke for 1-2 hours, do not be nervous, do not drink caffeinated and alcoholic beverages.
2. Sit in a comfortable position at the table, place your feet exactly. Put your hand on the table at heart level. Put the cuff above the elbow of 2.5 cm. Secure it to the arm with Velcro. Select sphygmomanometer with cuff size appropriate for your hand size. The average size is width 13 cm and length 35 cm. If you have a large or low weight, then buy a larger or smaller number of values. If you use the wrong size, then the pressure reading will be incorrect.
3. Next, rotate the wheel located under the pointer device to the maximum stop. Install a stethoscope on pulse point, feel it with your finger right or left hand, it depends on which hand you perform a measurement. Usually the pressure is measured on the left arm, but to check the results, you can use the right hand.
4. Inflate a bag of air readings 200. Very gently loosen the wheel. The arrow slowly begins to move. At the first sound of the pulse you will see readings systolic blood pressure. It means the force of ejection of blood from the heart.
5. The last sound will record on the device diastolic pressure, meaning the vascular tone, which made the blood output of the heart muscle.
6. Heart rate count at the second hand for 30 seconds and multiply the result by two. If you've been counting for 1 minute, then multiply the result not necessary.
7. The first measurement will seem quite difficult, but with time you will learn how to measure blood pressure and do it automatically.
