The goal of this observational study is to learn if saline results in improvement for patients with infection of their plerual space. The main question it aims to answer is:
What is the time to chest tube removal? Do these patients after need to escalate to fibrinolytics? Do these patients after need to escalate to surgery?
Participants will:
* Receive receive saline into their pleural space through an existing chest tube
* If they fail to improve, which will be determined by fluid size after treatment or signs of persistent infection, they will receive fibrynolytics through an existing chest tube
* If they fail to improve, which will be determined by fluid size after treatment or signs of persistent infection, they will be referred to surgery.
