During chest tube removal, which breathing action helps minimize air entry into the pleural space?

Explanation:
Controlling intrathoracic pressure during chest tube removal to prevent air from entering the pleural space. Exhalation increases pressure inside the chest, making it harder for air to be drawn into the pleural space as the tube is removed. This helps keep the pleural cavity closed off during the moment of removal. Inhalation would lower intrathoracic pressure, creating a gradient that could pull air in through the wound. A rapid, shallow pattern can cause unstable pressure changes and isn’t as protective as a controlled exhalation. So exhaling during removal best minimizes the chance of air entry.
