Ambulatory chest drainage.

Chest drainage is usually performed using the underwater drain consisting of re-usable glass units attached to the intercostal tube. Ambulatory chest drainage devices that use a mechanical one-way valve are an alternative to the traditional underwater drain. These devices consist of the flutter valve, flutter bags, chest seals and stoma bags. They are less bulky and allow the patient to be ambulatory, thus, reducing the risk of complications from immobility. Recent evidence shows that the ambulatory devices may be safe and effective for treatment of both pneumothorax and pleural effusion and even in out-patient care.
