They use three injections. First it's an anesthetic, sodium thiopental, it is a fast barbiturate that depresses the activity of the central nervous system. This injection unconsciousness the person and the injection is so strong that the pain is undetectable. The injection can reach the brain in 30 seconds for the person to go unconsciousness. After the sodium thiopental the exautor injects pancuronium bromide, this is for blocking the neuromuscular it also prevents the nerve messenger (acetylcholine) from communicating with his/her muscles. At the end the muscles are paralyzed. The last injection they use is the potassium chloride. This is the last dosage of the chemicals, the heart charges particles that interrupt its electrical signaling. It stops it from beating. The average time from the first injection to death is 8.4 minutes.
