Which of the following is an abnormal breathing pattern characterised by deep, gasping inspiration with a pause at full inspiration followed by a brief, insufficient release?

Correct option is A

Apneustic respiration is seen in cases of damage to the upper pons, leading to prolonged inspiratory effort followed by inadequate exhalation. It is a sign of severe neurological injury and often indicates a poor prognosis. The respiratory pattern is unique and different from other abnormal breathings seen in metabolic or cardiac conditions.
Explanation of options: (a) ✔ Apneustic respiration – Caused by pontine lesions, marked by prolonged inspiration and short, insufficient expiration. (b) ✘ Paradoxical respiration – Involves inward movement of the chest during inspiration, typically due to flail chest. (c) ✘ Kussmaul’s respiration – Rapid, deep breathing pattern associated with metabolic acidosis like diabetic ketoacidosis. (d) ✘ Cheyne-Stokes respiration – Cyclic breathing pattern with periods of increasing and decreasing tidal volumes followed by apnea.
