Very. Incorrect sizing could lead to measurement error when the mis-sized cuff fails to properly compress the brachial artery. Cuff size is determined by the size of the bladder, also known as the inflation bag. According to AHA and ANSI standards, the bladder should measure at least 80% of the intended limb circumference in length. The bladder width should measure at least 40% of its length. The cuff itself should then be designed AND marked to encourage or even restrict use to the limb circumference established by its bladder.

Material Safety Data Sheets are not required for most of our products and are not available in most cases. We do offer Material Safety Data Sheets for our mercury blood pressure instruments. These are available upon request OR by clicking here.

Latex sensitivity is a serious problem for both patients and healthcare workers. It is estimated that 7% of the general population and up to 17% of healthcare workers are latex sensitive, with reactions ranging from mild skin irritation to anaphylactic shock.

ALL ADC products are 100% LATEX-FREE.

ADC's 804 series gauge uses a quick release luer slip connector designed to allow rapid selection of the appropriate cuff. To attach, push and twist the tube connector into the gauge air inlet. When properly attached, less than 1/16" of the connector should show and the tubing should remain secure even under the harshest conditions. Do not force as it may be difficult to separate the connector from the port.

It depends on the manufacturer. In our case, it indicates that the gauge has been produced and tested to meet the U.S. Accuracy Standard of +/- 3 mmHg. This certification is our pledge and your guarantee for an accurate reading.

By law, both instruments must initially be within 3mmHg of a reference standard. However, because aneroid gauges rely on gears and mechanical linkages, mercury instruments will likely REMAIN accurate for a longer period of time. However, there is a trade-off; mercury instruments are generally not as portable and necessitate the use of 99.9999% pure elemental mercury, which is being banned by more and more municipalities and states.

Aneroid sphygs utilize mechanical gears and a mechanical linkage which can wear out or be knocked out of calibration. ADC aneroids are designed to provide a visual indication of accuracy. Our aneroid will require re-calibration if the indicator needle is outside the oval at the bottom of the dial. Unfortunately, when the needle is inside the oval, you can't be absolutely sure that the gauge is in calibration, unless it is a brand new unit from a reputable manufacturer (that's because gauges can be tampered with - some more easily than others).

All medical device manufacturers and most medical devices are regulated by the Food and Drug Administration (FDA). The FDA has accepted the sphygmomanometer standards established by the American National Standards Institute. The ANSI/AAMI/ISO 81060 series of standards set performance requirements for non-automated (aneroid & mercurial) sphygmomanometers as well as automated (electronic) sphygmomanometers. You may obtain copies of these standards by contacting ANSI or visiting their website.

A pacemaker will not cause interference. Defibrillators may cause some interference, but only at those times that the defibrillator is actively firing.

Five factors – Performance, Quality, Durability, Warranty, and Value.

• Performance: According to independent lab tests, ADC PROSCOPE and ADSCOPE stethoscopes perform as well, or better than comparable competitive models. Depending on model, they may include AFD Technology, PVC diaphragm rims and bells, ADSOFT eartips, bi-lumen design internal spring binaurals and convertible chestpieces for unmatched versatility.
