An airway pressure – absolute lung volume loop from an animal after lung lavage. EELV_ZEEP, end-expiratory lung volume at zero end-expiratory airway pressure; ILV-10 and ELV-10, absolute lung volumes at an airway pressure of 10 cmH₂O obtained from the inspiratory limb and from the expiratory limb, respectively; TLC, total lung capacity; MH, maximal volume hysteresis.
