There are two issues to consider in attempting to answer this type of question:
- Could the other device interfere with the RJL Analyzer?
For us to answer the first question is relatively straightforward. The presence of an implanted device in the body will likely have a small impact on the measured resistance and reactance values, which will, in turn have a small impact on the estimated body composition. However, this effect should be consistent between tests, so even if the body fat estimate (for example) is offset by the implant, if subsequent tests show the estimated body fat decreasing, you can be confident that the body fat is, in fact, decreasing.Implanted Cardioverter Defibrillators (ICDs) are a special category of device. Because they work by delivering a large voltage to the heart, there is a chance that the BIA may be damaged if it is connected when the Defibrillator discharges.
- Could the RJL Analyzer interfere with the other device?
You will need to ask the manufacturer of the other device. Give them the link to this page, and tell them that if they need more information, they can email email@example.com or contact us by phone.RJL Systems’ analyzers measure impedance using a 50 kHz sinusoidal signal that adheres to the requirements of IEC 60601-1:2007 for Patient Auxiliary Current in a Type BF applied device.
