How did the total air flow in this trial differ from that in the previous trial in which the pleural cavities were intact?

It was cut in half.

How did the pressure in the left intrapleural cavity change when the valve was opened?

It went from a negative number to zero and the pressure in the intrapleural cavity equalized with the atmospheric pressure.
