The image on the left includes the capnography tracing, while the one on the right does not. Note the augmented breath (A) and respiratory pause (B). The first post-pause breath (C) is in the direction of inspiration (negative polarity); lowest instantaneous heart rate during the respiratory pause (D). Note there is about a 3- to 5-sec sampling delay in the capnography tracing, as illustrated by the horizontal line below the tracing.
