Cross-tabulation of the proposed threshold (1.90 Pa·min) of the new volumetric capnography parameter (CapNoPE) against the diagnosis of pulmonary embolism (PE) (n=205)
| Parameter | Diagnosis | Total | |
| PE | No PE | ||
| CapNoPE <1.90 Pa·min | 44 | 55 | 99 |
| CapNoPE ≥1.90 Pa·min | 24 | 82 | 106 |
| Total | 68 | 137 | 205 |
