There are so many things that have come a long way in the medical field.  And there is no shortage in the future of these medical devices as they become more and more available to the general public.  I am very excited for devices like the Nonin ONYX that not only allow the public to be able to check their vitals by themselves.  But they can also do it with ease and flexibility.  There Is no big machine, only a devices smaller than a cell phone.  The battery powered heart monitor is everything to need to check vitals and monitor heart rate.
