Abstract:
Periodic alternating ping pong gaze (PAPPG) represent a particular entity among abnormal ocular movements sometimes observed during coma. They usually result from a widespread bilateral hemispheric ischemia. A case of PAPPG is reported that presents a twofold particularity: the lesion responsible for the abnormal movement, although eventually bilateral, was initially unilateral, and the PAPPG were intermittent and associated with a Cheyne-Stokes respiration. This latter finding requires reconsideration of the nature of the stimulus responsible for this curious abnormal ocular movement.

Assessment of Ventilation II: Respiratory Depth and Rhythm
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:
