A good article from the British Journal of Healthcare Assistants, it looks at preparation and equipment, the procedure, factors that can negatively affect the readings, the rationale for taking the readings, the mechanism behind it, and oxygen saturation. A useful article for new staff and those teaching more about oxygen saturation.
