Etymology: Fr, panteler, to gasp
a ventilatory pattern characterized by rapid, shallow breathing commonly used during labor. Panting usually moves gas back and forth in the anatomical dead space at a high flow rate, which evaporates water and removes heat but produces little or no alveolar ventilation. It does not usually cause carbon dioxide levels to be affected. Compare hyperventilation.
panting(pant'ing) [ME. panten]
Short, shallow, rapid respirations. Synonym: polypnea
rapid, shallow breathing, a characteristic heat-losing reaction in dogs; represents an increase in dead-space ventilation resulting in heat loss without necessarily increasing oxygen uptake or carbon dioxide loss.
