Is it possible to get blood pressure from a person without touch?

Introduction

Blood pressure is a critical vital sign that is often measured using a cuff wrapped around the arm. However, some people feel anxious or uncomfortable during this process, which can lead to inaccurate readings especially around doctors or nurses which often causes white coat syndromes, a condition that occurs when blood pressure readings are higher than they are in other settings, such as at home. Additionally, some patients may require frequent monitoring, and a traditional cuff may not be convenient. Therefore, it is natural to wonder if there are ways to obtain blood pressure readings without touching the patient. In this article, we explore the possibility of getting blood pressure from a person without touch.

Non-invasive methods of measuring blood pressure without touch

There are various non-invasive methods of measuring blood pressure without touching the patient, lets detail some of these here:

Oscillometric blood pressure monitoring

Oscillometric blood pressure monitoring is a non-invasive technique that measures the pressure changes in the artery by detecting the pulse waves using an electronic sensor. The sensor is placed on the patient's skin, usually on the wrist, and connected to a monitoring device. The device can then display the blood pressure readings.

Photoplethysmography

Photoplethysmography is a non-invasive technique that measures changes in blood volume by detecting light absorption in the skin. A device called a pulse oximeter is placed on the patient's finger or earlobe, which then uses a light source to detect changes in blood volume.

Smartphone applications

Advancements in technology have made it possible to measure blood pressure remotely using a smartphone application. The applications use the phone's camera and light absorption to detect changes in blood volume in the fingertip or the face. This is what we do at Vastmindz.

Benefits of measuring blood pressure without touch

Convenience and comfort

Measuring blood pressure without touch can be more convenient and comfortable for patients who require frequent monitoring. Non-invasive techniques can also be used in situations where traditional cuff methods are not possible or appropriate, such as in patients with burn injuries or infants.

Reduced risk of infection

Touchless blood pressure monitoring reduces the risk of infection and cross-contamination that may occur with traditional cuff methods.

Improved accuracy

Some patients may experience anxiety or discomfort during a traditional blood pressure measurement, which can lead to inaccurate readings. Non-invasive methods may reduce these effects, leading to more accurate blood pressure readings.

Frequently Asked Questions (FAQs)

Can you get accurate blood pressure readings without touch?

Yes, non-invasive techniques such as oscillometric monitoring and photoplethysmography can provide accurate blood pressure readings without touching the patient.

Are smartphone applications reliable for blood pressure measurement?

While smartphone applications are convenient, their accuracy may vary. Patients should consult with their healthcare provider before using smartphone applications for blood pressure monitoring.

Conclusion

In conclusion, it is possible to get blood pressure from a person without touch using non-invasive methods such as oscillometric monitoring, photoplethysmography, and smartphone applications. These methods can be more convenient, comfortable, and safer for patients, and may improve the accuracy of blood pressure readings. The technolog is evolving and we are proud at Vastmindz to be leading the way in extracting Vital Heatlh signs using mobile applications. Patients should consult with their healthcare provider to determine the best method for their individual needs.
