Kapitel 2755: Delayed chest closure

The operation of the internal floating catheter was very simple. Zheng Ren put on sterile gloves and completed the operation within one minute.

A floating catheter was implanted into the right internal carotid vein, and the measured heart rate was 6.1L/min, and the SnO2 was 51%.

The anesthetist picked up a pen washi and was about to start calculating when Zheng Ren said in a deep voice,"there's no need to calculate. The cardiopulmonary circulation resistance is 760/CM5."

"..." The anesthetist and Zhao Yunlong were both stunned. Not only them, even Su Yun was stunned.

To measure the displacement of the heart with a floating duct, one had to calculate the internal circulation resistance through a more complicated formula, but boss Zheng could calculate it mentally?

He must be cheating. Su Yun calculated the same number five or six seconds later. He cursed in his heart.

"Boss Zheng, why are you so narrow-minded?" Zhao Yunlong asked.
