Emergencies can happen anywhere. Wherever humans go, medical emergencies will follow, regardless of time of day, year, or location. It would be nice if every EMS call occurred indoors, under well lit and environmentally stable conditions. But that's usually not the case. In fact, some medical emergencies are the result of the patient being exposed to extreme weather, which affects not only the patient, but also the rescuers and their equipment. And in the case of vital tools like your portable suction unit, they, like you, had better be up to the task.
