Cushing's Triad indicates increased intracranial pressure and includes which respiratory finding?

• A. Bradypnea
• B. Apnea
• C. Normal respiratory rate
• D. Tachypnea

Answer: (D)

Cushing's Triad signals rising intracranial pressure and, in the respiratory component, shows an irregular breathing pattern rather than a steady rate. This irregularity comes from brainstem irritation and compression during ICP elevation, and you may see patterns such as periods of faster breathing interspersed with slower breaths or pauses (Cheyne-Stokes or other irregular respirations). The key point is that the respirations are disrupted and not simply rapid, slow, normal, or absent in a regular pattern. Recognizing irregular breathing alongside the hypertension with wide pulse pressure and bradycardia helps indicate escalating ICP.
