Certified Hyperbaric Technologist Practice Test 2025 – Comprehensive Exam Prep

The choice to re-membrane a TcOM (Transcutaneous Oxygen Monitoring) electrode is primarily based on its performance and calibration status. When calibration fails, it signifies that the electrode is not providing accurate readings, which can compromise patient monitoring and treatment decisions. Re-membraning the electrode ensures that it returns to an optimal functioning state, allowing for reliable and accurate transcutaneous oxygen measurements. This process helps maintain the integrity of patient care by ensuring that oxygen levels are monitored accurately, which is critical in hyperbaric medicine.

In contrast, re-membraning after every use may be unnecessarily frequent and could lead to increased costs and waste of materials, while re-membraning every week regardless of use may also not be efficient as the electrode may still be functioning correctly. Re-membraning only if a patient has a reaction does not address the root of potential inaccuracies if the calibration has already failed. Thus, addressing calibration issues is the most appropriate context for re-membraning the electrode.
