The "Heber-Drain" is based on the Heber principle, which uses hydrostatic pressure to transfer fluid from the chest to a collection canister. It produces permanent passive suction. As the Heber drain is a classical gravity drain, the canister must be placed below chest level to be active. The difference in height between the floor and the ...
Chest tubes are also provided in right angle, trocar, flared, and tapered configurations for different drainage needs. As well, some chest tubes are coated with heparin to help prevent thrombus formation, though the effect of this is disputed. [16] Chest tube have an end hole (proximal, toward the patient) and a series of side holes.
Supercritical fluid extraction (SFE) is the process of separating one component (the extractant) from another (the matrix) using supercritical fluids as the extracting solvent. Extraction is usually from a solid matrix, but can also be from liquids .
The lung to be washed is filled with fluid by gravity, then drained. Drainage can be done by suction [2] or gravity. [10] Some versions add a shaking step between the filling and draining to help with the washing. [2] The procedure typically uses 10–20 liters of fluid per patient, but severe cases require up to 50.

This enables air and fluid to be unidirectionally extracted from the pleural cavity. [36] Chest tubes are usually removed one week after surgery along with any stitches or staples in the incisions. Patients experiencing shortness of breath will be guided through deep breathing or coughing exercises by a physician or respiratory therapist.
