The patient cot has a thin, firm mattress that lays directly on an aluminum frame and provides very little comfort. Unfortunately, the cot must be firm in order for us to perform CPR on critically ill patients. In addition, we try to respond to medical emergencies as quickly as possible in order to provide timely, life-saving treatment. Consequently, this requires vehicles with good road-handling characteristics. If these large, heavy vehicles had a softer, more "spongy" suspension that would provide a smoother ride, they would not be safe to drive to the scene as quickly as possible.
