After seven seasons of Emergency!, the series' two lead actors, Randolph Mantooth and Kevin Tighe, learned quite a bit of lifesaving information. They studied, worked with real paramedics, and got a crash course in medical training.

Both actors used their roles to educate people on how to properly save lives, which some viewers took advantage of in times of need. Mantooth played the role of Johnny Gage, while Tighe played Roy DeSoto.

According to a 1976 interview with The Daily Advance, the more both actors involved themselves with emergency medical techniques, the more respect they gained for their real-life counterparts.

"We've long been aware of their dedication, their capabilities under very difficult and stressful conditions," Mantooth said. "What really impresses me is how they master that special language of theirs."

"I'd hate to imagine what some visitors from another planet would conclude if the place they landed was an accident scene with a couple of paramedics doing their thing," Tighe added.

According to the interview, Tighe repeated a few of his lines from a recent script, which involved heavy jargon from the industry. His job in the script was to report the status of an accident victim to his onscreen hospital colleagues.

"He was in V-fib," Tighe read. "We defibrillated two times. He is now in sinus tachycardia. Pulse 120. Standby for BP."

Then it was Randy's turn to speak: "BP is 80 over 50. Rales and rhonchi bilaterally, mild cyanosis."

As for what that all meant, Mantooth and Tighe admitted they had no idea—but they were working to learn and study medical jargon. In the meantime, simply pronouncing it was tough enough for the duo.

The appreciation for people in the field kept growing as the two actors kept growing in their roles. 

They had to be great actors while also being great in the medical field, essentially learning a whole new language. According to Mantooth, the real professionals who react quickly without any scripts were the ones they respected most.
