The days of going to the doctor to get a sense of your blood pressure are almost all but a distant memory. Automated blood pressure machines are rapidly replacing the stethoscope, pump, and gauge method in physician offices worldwide.
However, by taking on more automated technology, we’re also taking on more responsibility in ensuring that the machine is working properly and that we are using it correctly. Several factors can trigger an error in modern equipment, and in this article, we will look at some of the most common errors and how to remedy them.
Most Common Errors
Firstly, if you have a relatively new blood pressure machine, it’s worth bearing in mind that the vast majority of errors encountered are due to excessive movement during the reading or an improperly fitted cuff. Errors marked as ‘E’ are the most common, such as the “E3” error, which is also caused by one of the reasons mentioned above.
Other Common Errors
It’s also worth having a basic understanding of some of the other errors you may encounter. Here is a quick overview of the reasons for the different error codes.
Error code E
Reason – The monitor is not detecting your pulse correctly
How to resolve – Remove and replace your cuff. Ensure it’s fitting properly and in the right place.
Error code Err
Reason – Your blood pressure level is unstable due to some movement
How to resolve – Clear the error and try again. Remain still and silent while measuring.
Error code Err 0
Reason – Your blood pressure values are within 10 mmHg of each other
How to resolve – Remove and replace your cuff. Ensure it’s fitting properly and in the right place.
Error code Err CUF
Reason – The cuff is not applied correctly or is loose
How to resolve – Remove and replace your cuff so it’s tight enough that it doesn’t slide down your arm but loose enough for you to fit a few fingers between the cuff and your arm.
Error code Err E
Reason – Problem with device
How to resolve – Remove the batteries, press the power button, and replace the batteries. If you still see this error, contact the manufacturer for support.
Error code Err 9
Reason – Problem with device
How to resolve – Same as above
Error code Err 10 / 11
Reason – The monitor didn’t pair with another device (like a smartphone or tablet)
How to resolve – Remove and replace the batteries, then try pairing again.
What Causes Error Codes in Blood Pressure Machines?
Defective equipment is often the most common answer users jump to when they encounter an error display or inaccurate results from a blood pressure machine. While this may be possible, it’s much more likely that there is a much simpler reason.
Before you decide to have your next check-up, keep the following points in mind.
Keep still – Movement of any kind can cause significant fluctuations in the measurement results. Posture also plays a major role, so be sure you are sitting in a natural position and not leaning against anything. Also, ensure that you are not slouching or cross-legged, and keep silent.
Check the cuff – Firstly, ensure that the cuff is fitting properly. A cuff that is too loose or too tight will affect the reading or not provide one at all. Next, you want to ensure that the cuff is fastened in the correct position. The marking on the cuff should be aligned over the brachial artery so that the reading is not impaired in any way.
Check the air hose – Sometimes, the air hose may be damaged or leaking. Make sure the hose is not tangled and that nothing is applying pressure to it. You can identify a leak by listening to the sound of air coming from the hose.
Conclusion
Checking your blood pressure regularly is essential to understanding your risk level for serious illnesses such as heart disease or stroke. Modern advancements in automated testing equipment have made it easier to have these tests conducted anywhere, and at any time you feel convenient.
An E3 error, like most errors, is caused due to basic incorrect usage of the equipment and can be resolved easily by ensuring that you use the equipment correctly and take the steps necessary to allow the machine to provide an accurate reading.
