A man is brought back to life through regeneration using a high tech machine. During close-ups of the machine's display panels, we see the words "Perotid Gland" in big, bold, red letters. It should have been spelled "Parotid Gland".
When Oscar goes into cardiac arrest after being revived, he is stabilized by injecting lidocaine into his heart.

First-line cardiac drugs (according to the Advanced Cardiac Life Support guidelines) are always administered through an already established IV line.
