What is the meaning of medical term provisional?

The medical term "provisional" means something that is temporary, not fully developed or not established. It is often used to describe a diagnosis not yet confirmed or a procedure performed as a temporary measure.

A provisional diagnosis is made when a doctor suspects a particular condition based on the patient's symptoms and signs but needs further testing to confirm the diagnosis. For example, a doctor may make a provisional diagnosis of pneumonia based on a patient's cough, fever, and chest pain but order a chest X-ray or other tests to confirm the diagnosis.

A provisional procedure is performed when necessary to address a patient's immediate needs temporarily but will eventually be replaced by a more permanent solution. For example, a provisional tracheostomy may be performed on a patient who needs help breathing but will eventually be able to breathe independently once their condition improves.
