It makes sense that a relatively controlled environment, such as a hospital, has different suction requirements than unpredictable prehospital care environments. Portable suction units are generally thought of as tools to be used in the EMS setting alone and may not be given much thought in the hospital setting. This is an error that hospitals cannot afford to make. Beyond the needs of crash carts and emergency departments, suction units should be a key aspect of the hospital’s disaster plan. Here, we compare the needs of both prehospital and hospital suction units and how the right choice of suction unit can make an impact on both your efficiency and your patients’ outcomes.
