| Factor | pulmonary vascular resistance (PVR) |
| Description | The PVR decreased significantly from 5.0 ± 2.6 W to 2.8 ± 2.2 W (P = 0.0001) with a significant increase in the Qp:Qs ratio, from 3.2 ± 1.4 to 4.9 ± 2.4 (P = 0.0008) after 100% oxygen inhalation. |
| Biomarker | YES |
| Classification | E10 (physiological factor - other) |
| Association | |

| Application | risk assessment |
| Objective | The aim of this study was to analyze the relationship between the pulmonary venous blood flow velocity-time integral (VTIpv) and PVR. |
| p Value | 0.0001 |
| Conclusion | The PVR decreased significantly from 5.0 ± 2.6 W to 2.8 ± 2.2 W (P = 0.0001) with a significant increase in the Qp:Qs ratio, from 3.2 ± 1.4 to 4.9 ± 2.4 (P = 0.0008) after 100% oxygen inhalation. |
