Manufacturer Narrative

A remote service engineer (rse) spoke to the customer and confirmed that the configuration had the low alarm delay set at 10 seconds, and the desaturation delay set at 20 seconds, so the rse explained that it could possibly be 30 seconds before a desaturation alarm occurs.It was confirmed that spo2 was a solid pleth waveform with no artifact.A good faith effort (gfe) was performed to clarify the issue, and it was indicated that the patient's spo2 values were varying widely, causing the algorithm's delay condition to not be met, though the customer expected an alarm immediately.It was also indicated the patient's spo2 values were above the alarm limit a majority of the time.The customer declined onsite dispatch.Based on the information available, the reported issue was caused by user error / user missunderstanding.
