When should a discrepancy in the air kerma meter readings be investigated?

The appropriate time to investigate a discrepancy in the air kerma meter readings is when the readings suggest maximum exposure near limits. This is crucial because the air kerma meter measures the radiation dose delivered to the patient, and discrepancies could indicate potential overexposure, which poses a risk to patient safety. If the readings indicate that the exposure is approaching or exceeding established safety limits, it is imperative to conduct a thorough investigation to determine the cause of the discrepancy, ensure equipment functionality, and protect patients from possible harm.

Regular monitoring of these readings is part of best practices in radiation safety, so if significant discrepancies arise, they should not be overlooked. Different scenarios, such as routine maintenance or patient discomfort, are essential to consider, but those situations typically do not warrant immediate investigative action like discrepancies near maximum exposure limits do. Therefore, addressing discrepancies in alignment with safety protocols is vital for maintaining the highest standards in fluoroscopic procedures.
