Philips h2h q&r has completed the investigation for the report of a bp cuff causing bruising after use.The device was not returned for investigation so testing on this specific device was not possible.However, the vendor (a&d) previously investigated bp cuffs of the same product family that caused bruising after use.A&d conducted a maximum inflation level test since over-inflation is the most common cause of arm bruising during/after use.The returned devices stopped inflation at 299 mmhg and met the safety design requirement of 300 mmhg.The inflation level of the bp measurement depends on the patient¿s hypertensive condition.The bp cuff will inflate higher if the patient is more hypertensive and lower if the patient is less hypertensive.Higher pressure generated by the device will result in a tighter obstruction, whereas lower pressure will result in a looser obstruction.Thus, a tighter obstruction may lead to a higher change of skin bruising and feeling discomfort or a resulting bruise is possible for hypertension patients.The patient who reported this incident¿s hypertensive condition is unknown.This complaint is confirmed for bruising but not confirmed for a device malfunction as the device was not returned for investigation.H2h q&r will continue to monitor for trends.
