  • Causa
    According to the record holder, there is a unit conversion error in the metric setting for weight and height that can result in incorrect calculation of the body surface area. all of the following events must occur to create a hazardous situation: - system-wide drives are set to "metric" in the setups; - the patient data screen is open, the patient's name, weight and / or height have been entered, the patient data screen is closed; - an image is captured, the examination is terminated; - the system is restarted and the patient directory is opened (but not the patient data screen, or the problem will not occur), - the original examination is included (it does not matter whether through the option "add" or "create". /// when this happens, the system incorrectly converts metric height / weight values ​​to english while still retaining the metric units identification. the displayed height / weight values ​​are incorrect in the report, and the bsa (body surface area) calculation, which depends on height / weight, will be incorrect.
  • Acción
    Philips will do a field correction of the problem by updating the software. You can confirm that your system has been affected by verifying the software version. Philips has corrected this problem in versions 1.0.3 and higher. If you have a software version affected, contact your local representative to schedule your upgrade. ///// Recommendation: Until your software can be updated, the situation can be avoided by ensuring that the "Patient Data Units" setting is set to "English" units. If this setting is not acceptable to your institution and you need to use the "Metric" units, you can avoid the problem by ensuring the following: 1. After turning on the system, open the Patient Data screen before including an examination. This will put the Patient Data screen back in an appropriate status and the problem will not occur. 2. Ensure that the Patient Data screen is maintained in the Metric units instead of English units. If a height or weight value has to be reported in English [English] units, then it must be converted to Metric manually to avoid the problem. Finally, ensure that the Patient Data screen is using the Metric units before loading any survey data. This will prevent your data from being altered.
