Advice from the BP Measurement Experts

Kiosk Users Get Advice from FDA on Accuracy of BP Measurement

Illustration of a Blood Pressure Monitoring Kiosk

Do you ever see a kiosk that measures blood pressure (BP) and take a seat to see how you fare? Well, make sure you are aware of the latest information regarding accuracy of kiosk BP measurements. On June 24, 2014, the US Food and Drug Administration (FDA) issued a consumer update for blood pressure monitoring kiosks. In this update, users are advised that blood pressure cuffs on public kiosks do not fit everyone and consequently, may not provide accurate BP readings for every user. Luke Herbertson PhD, Biomedical Engineer at the FDA stated, “[BP kiosks] are easily accessible and easy to use. But it’s misleading to think that the devices are appropriate for everybody. They are not one-size-fits-all.” Users with arm circumferences outside of the cuff range may receive inaccurate BP values.

The Material World of BP Cuffs

The Material World of BP CuffsSo what’s in a fabric?  And why do manufacturers come up with so many choices?

Choosing the correct fabrics for medical products can be a bit more complicated than selecting the right material for a pair of jeans.

FDA Calls for Connector Standardization

Click to view the video on SunTech's Cuff Standardization ProgramTubing misconnections, wrong route errors, catheter misconnections or Luer misconnections: the FDA isn't picky about what you call them – they want them eliminated. Multiple and sometimes fatal connection errors between various medical devices, including blood pressure cuffs, have led to the need for standards designed to eliminate this potential. The intent is to achieve this by designating specific connectors for defined types of devices. Blood pressure cuffs are one of the device groups identified by the FDA for standardization1.

What is a "Long" Blood Pressure Cuff?

Long size BP cuffAs a manufacturer of blood pressure (BP) cuffs, we are often asked: “What is the difference between an Adult BP cuff (or “standard” cuff) and an Adult Long BP cuff?”

Simply put, a “long” cuff has the same range indicators and bladder size as a “standard” cuff, but the actual length is longer than that of a “standard” cuff.  Therefore, a “long” cuff is able to fit on a larger patient population than a “standard”  cuff.

You are probably asking yourself, “If the range and the bladder size is the same on both a “standard cuff” and a “long cuff”, do they both give accurate readings?”

Blood Pressure Monitoring and Infection Control

Electron microscope imageInfection control has long been a hot topic for acute-care hospitals, and has been the focus of patient advocacy groups, the popular press, and legislators for some time. Old stories of sponges and instruments being left inside patients by harried doctors and nurses have been supplanted by nightmarish scenarios containing ominous-sounding names like Clostridium difficile and Methicillin-resistant Staphylococcus aureus. Unfortunately, for many patients in today's healthcare system, hypothetical scenarios and clinical studies have become a real matter of life and death. As a result, the spotlight is expanding to include other areas of the healthcare continuum-including long-term care facilities.

Preeclampsia: Pregnancy and Hypertension

PreeclampsiaAn important health issue that expectant mothers may encounter during pregnancy is Preeclampsia, a condition in which the expectant mother is diagnosed with hypertension and has protein present in the urine.  Preeclampsia is the most common medical disorder of pregnancy and affects 10%-12% of all expectant mothers (Pickering et al, 2005).  Since blood pressure plays an important role in the health of mom and baby, accurate blood pressure measurement is extremely critical, because one would never want to be misdiagnosed with hypertension and be prescribed medications/medical interventions that could potentially injure both mom and baby.

With the obesity epidemic increasing globally, the need for larger blood pressure cuffs is becoming more pronounced. The World Health Organization states that "currently more than 1 billion adults are overweight - and at least 300 million of them are clinically obese."1
