Expiratory apnea is the temporary cessation of breathing following expiration. During physical examination, particularly cardiac auscultation, a clinician may ask a patient to exhale and briefly hold their breath in order to reduce respiratory sounds and chest wall movement, thereby facilitating clearer auscultation of heart sounds with a stethoscope.
