The normal RSBI value is approximately which of the following?

Explanation:
RSBI, the Rapid Shallow Breathing Index, is calculated as respiratory rate divided by tidal volume in liters and reflects how efficiently a patient is breathing. A lower RSBI means slower, deeper breaths and generally better readiness for weaning, while a higher RSBI indicates rapid, shallow breathing and more work of breathing. In practice, around 105 is the commonly used threshold: RSBI near or below this value predicts a higher likelihood of successful extubation, whereas values around or above this point suggest increased risk. So the approximate normal value clinicians reference is 105.
