The new Palm Evo from Redax is a battery powered, rechargeable suction unit used in conjunction with the renowned Redax chest drainage device. It provides mobile suction for post operative thoracic patients, which facilitates their early mobilisation and independence from traditional wall suction. In addition Palm Evo is a digital air leak monitor that provides both instantaneous and cumulative (100 hours) data including the patient’s air leak and pleural pressure history. The data is displayed in both absolute values and graphics. The information provided allows an improved understanding of how the lung-pleural cavity system is working in individual patients, and supports the safe removal of the chest drain.
