Options: <1> Regular frequency and superficial character. <2> Absence of clearly observable breathing. <3> A series of breaths that increase in amplitude / intensity to a maximum point in which they begin to decrease, followed by an apnea pause. <4> Slow and regular breaths with a frequency less than 10 per minute. <5> It is an abnormal and sustained increase in both depth and respiratory rate.

Output: 3
