Eupnea: inspiration is active, expiration is passive. – Abdominal breathing – Thoracic breathing Patterns of respiration Forced breathing: respiratory movement is greatly enhanced during physical exercise. Both inspiration and expiration are active

Thoracic respiration and abdominal breathing Infants：Abdominal respiration mainly. Adults：Mixed breathing patterns. Thoracic respiration : respiration effected chiefly by the action of the intercostal and other muscles that raise the ribs, causing expansion of the chest. Abdominal breathing breathing that is done by contracting the diaphragm
