Yes. But "Emergency's" bread and butter were the rescues. Particularly the "danglers". People trapped on cranes and building ledges and stuff.
About all the medical stuff the paramedics actually did was CPR and inserting IVs.
That said I've listed Emergency as one of the most influential television shows in the U.S. of all time given it sparked the massive increases in the creation of EMS services around the country.
Note, Emergency was a very heavily based in reality show. The fireman who drove the fire engine was Fireman Specialist Mike Stoker who used his real name on the show, was certified to drive the engine in real life and had an SGA card which meant the show didn't need a separate person to drive the engine for filming. He later retired as a captain in the LAFD. The captain on the show for the first season was a real life captain in the LAFD.
And teen idol Bobbie Sherman after guest starring as a doctor on Emergency was inspired to change careers and become an emergency first responder himself.
All fine and well but currently market is full of medical dramas. Not ER, EMT but medical ones in general. When this show came out it was probably only one with such theme, something not true today. So it's not about quality, it's about getting enough audience.
To give you related example, look at how many police procedurals are out there and each season there is at least one new one (or at least LE related). And yet most get axed because market is so saturated with them it's hard for them to draw in enough audience.
