The Pneumonectomy Balanced Drainage system provides surgeons with a safe and effective way to evacuate air and fluid from the pleural space following a pneumonectomy, providing a safe alternative from traditional drains for this special and delicate type of patient.
A-4301-08 Pneumonectomy Unit
The model is composed of 3 chambers
NOTE: There is no high negativity float valve. If patient negative pressure in pnuemonectomy space reaches –13 cm, atmospheric air will be pulled into the system through the small arm of this column.
The patient pressure will be "balanced" between +1 cm (red chamber) and -13 cm (blue chamber). This helps keep intrapleural pressure at a mean average of -6 cm of H2O, the physiological "norm".
