Comparison of time taken to obtain an arterial blood gas result at the bedside using the Proxima point of care machine vs. a standard remote arterial blood gas analyser: A randomized controlled trial.

Introduction: The Proxima point of care (POC) device enables arterial blood gas (ABG) samples to be analysed without the nurse leaving the patient. The benefits of this for work efficiency have not been evaluated.

Methods: We compared the time taken to obtain an ABG result using Proxima versus a standard ABG sampling system.
