Phase 3 becomes indistinguishable when physiological dead space increases,as in chronic obstructive pulmonary disease (COPD),and causes the capnogram to appear as it does in the figure.A cardiac arrest would lower the graph line to zero.Hyperventilation will decrease the alveolar plateau,but its shape would remain the same as a normal capnogram.A pulmonary embolism would also cause a drop in the alveolar plateau.
