US Guided Thoracentesis

[@melvillefletcher4332]

Question: is it safe to do thoracentesis if the pleural effusion is say 5cm but the lung tip gets close to pleural line at end inspiration? If yes, what can be done to mitigate risk of pneumothorax in this case? To be clear, I mean _only_ the lung tip seem to get close to pleural line/chest wall not the entire lung.
