    In medicine, pacemakers are hysteretically delayed so as not to interfere with the activity of the sinus node or the heart. The behavior of the isolated lung, insufflated with air, is also hysteretic. The pressure-volume relationship obtained in such experimental conditions allows us to identify a marked difference in behavior during insufflation and deflation, with much lower pressures at the same volume during deflation than during inflation. The same curve can be drawn if, instead of insufflating air into the lungs, it is placed in an airtight container and then emptied by means of a pump. The pressures recorded by a manometer, usually water, connected to the pump will be negative.
