Who is authorized to draw an Arterial Blood Gas (ABG) sample?

The authorization for drawing an Arterial Blood Gas (ABG) sample is specifically designated for healthcare professionals who possess the necessary training and skills to ensure the procedure is done safely and accurately. This group includes respiratory therapists, nurses, and physicians. Each of these professionals has undergone education and training that enables them to understand the anatomy, potential complications, and proper techniques required for arterial puncture, which are critical in obtaining ABG samples.

Respiratory therapists, for instance, are typically well-versed in respiratory function and the significance of blood gas measurements, allowing them to understand the implications of the results. Nurses often receive training in phlebotomy and may be required to perform ABG draws as part of their clinical practice. Physicians, particularly those specializing in internal medicine, critical care, or emergency medicine, are equipped to handle such responsibilities, given their comprehensive medical training.

It is important to identify specific roles in the medical field for performing procedures like ABG draws, as this upholds standards of care and patient safety. Other options, such as microbiologists, laboratory technicians, or medical assistants, while integral to the healthcare system, do not routinely have the responsibilities or training associated with performing arterial punctures for blood gas analysis.
