Our current compartmentalized society has deemed that doctors should perform these tasks, though turf wars abound over what nurses, physician assistants, pharmacist, paramedics, and others should legally be permitted to do. Recent decades have also seen the trend toward home care for I.V. therapy, nebulizer treatments, dialysis, and much more. The take home lesson is this: the layman can acquire many skills once considered the purview of health professionals alone. Thus, the first step in acquiring these skills is believing that you can do so.
The next question is to identify what skills you’d like to acquire. Though an unknown future presents unknown threats, common injuries and diseases will no doubt persist. Patients suffering lacerations, infections, sprains, and broken bones fill the ERs. Infections, diabetes, asthma, pneumonia, chest pain, arthritis, GI disturbances, urinary problems, STDs, and assorted rashes comprise the majority of medical problems. Learning how to diagnose and treat these problems is a good place to start.
