You will not understand even if I tell you.

"Calculation of the inferior vena cava's inhalation collapse: （Max D-Min D）/Max D× 100%。”Zheng Ren explained when he saw principal Zhang's blank expression.

"Place the probe under the sword to the right, and the scan plane is parallel to the inferior vena cava. The image shows the right atrium, inferior vena cava, and hepatic vein.

Under normal circumstances, the inferior vena cava would obviously collapse with deep inhalation. The diameter of the inferior vena cava was less than 2.1 cm, and the rate of inhalation collapse was& gt, 50%, which was 3 mmhcg.

When the right atrial pressure is high, the diameter can be& gt, 2.1 cm, and the rate of inhalation collapse is <50%, which is 15 mmhcg. "

Zheng Ren was like a machine gun, speaking in one breath, not giving the others time to think.""The diameter of the inferior vena cava is 2.4 cm, and the rate of caving in after inhalation is <50%. This can clearly prove that it's a pulmonary embolism."
