What happens when Mildred overdoses? Who shows up to their house? How is Mildred treated?

In the beginning of the book, Montag returns home and discovers that his wife Mildred has overdosed on sleeping pills. As he enters their bedroom, he trips over an object, which is to revealed to be a "small crystal bottle of sleeping tablets which earlier today had been filled with thirty capsules and which now lay uncapped and empty in the light of the tiny flare." It is apparent that Mildred had ingested all of the pills. Montag notices that Mildred is stock-still and barely breathing, indicating that she is close to death.
Montag calls the “emergency hospital” for help. Two men from the emergency hospital who are not doctors, but rather machinists, enter their home with two machines. One machine removes the toxic substances from Mildred’s body. The other machine pumps the tainted blood out of her body and replaces it with fresh, clean blood and serums. Montag is perturbed by the fact that the operators are not doctors, but they are indifferent towards the matter because they “get these cases nine or ten a night.” Thus, it was deemed unnecessary for any real medical doctors to be present. In the end, Mildred is saved and acts as if nothing had happened the very next morning.

Very near the beginning of the book Fahrenheit 451, the main character, Montag, comes home to find that his wife Mildred has overdosed on sleeping pills. When he comes into their bedroom, he at first thinks she is asleep, but then he sees that her eyes are open and glassy, and he finds a "small crystal bottle of sleeping-tablets which earlier today had been filled with thirty capsules and which now lay uncapped and empty in the light of the tiny flare."
Montag makes a call to the Emergency Hospital, and two men, who are more like handymen than doctors, come to the house, bringing two machines with them. One machine is used to suck out the contents of Mildred's stomach, and the other is used to simultaneously drain Mildred's blood and replace it with new, fresh blood as well as serum. Unfortunately, the two men who come to operate these machines are very uncaring about Montag and Mildred's situation, probably because they "get these cases nine or ten a night." Mildred's life is saved, and in the morning she acts as if she doesn't remember taking any pills.
