Pulmonary embolism capnography waveform
Pulmonary Embolism
If the waveform takes on a near-normal shape (see Figure 4c, p. 50) then the placement of the advanced airway was successful.8
Bronchoconstriction also causes the rectangular-shaped capnography waveform to have a "shark fin" appearance. A rectangular waveform indicates that ...

The normal end-tidal capnography wave form is basically a rounded rectangle. 2 (See Figure 1, p. 48.) When a person is breathing out CO2, the graph goes up.
