What ventilation rate is used in BLS trauma protocols?

• A. O2 and/or ventilate at a rate of 10/min PRN
• B. O2 and/or ventilate at a rate of 8/min PRN
• C. O2 and/or ventilate at a rate of 12/min PRN
• D. O2 and/or ventilate at a rate of 20/min PRN

Answer: (A)

Ventilate at about 10 breaths per minute when needed. In BLS trauma care, the goal is to provide enough ventilation to oxygenate without driving hyperventilation. A rate of 10 per minute (roughly one breath every 6 seconds) strikes a balance: it supports adequate oxygen delivery with bag-valve-mask or other devices, while minimizing the risk of increased intrathoracic pressure and gastric inflation that can come with faster rates. PRN means you give breaths as needed based on whether the patient isn’t breathing or isn’t ventilating adequately. The other rates would either under-ventilate or over-ventilate: too slow may not provide enough oxygen, too fast can worsen hemodynamics and cause discomfort or complications.
