Final answer:
For a patient on low-concentration oxygen therapy without acute respiratory distress, the NYS BLS Treatment Protocols recommend the use of a Nasal Cannula during transport.
Step-by-step explanation:
According to the NYS BLS Treatment Protocols, if a patient is on physician-prescribed low-concentration oxygen and is not in acute respiratory distress, the recommended type of oxygen delivery device to use during transport is a Nasal Cannula. This option provides a low and regulated flow of oxygen, which is suitable for patients who do not require high concentrations of oxygen or are not experiencing severe respiratory issues. Devices like a Non-rebreathing mask or Demand valve provide higher concentrations of oxygen and are typically reserved for patients in more critical conditions. A Simple face mask could also deliver higher concentrations of oxygen than necessary for a patient prescribed low-concentration oxygen therapy.
