Cardiac Arrest

The first scene sees Dr. Rajesh Rajah waking up in the bed with Nurse Reece after having had a skinful the night before. A fresh faced Dr. Andrew Collin arrives on the wards finding himself unprepared for the situations with which he has to deal, including that of the asbestos patient, Albert Gray. The suited consultant surgeon Mr. Betancourt also makes his first appearance. He is revealed to be Maitland's lover and heavy critic of SHO Monica Broome.

Due to a bomb scare at the General, the hospital is overrun with patients. New doctors are introduced. Phil Kirkby (played by Andrew Clover) is eager, but tries too hard to impress. Smedley (Peter O'Brien of Neighbours fame) is the new registrar, who impresses the other doctors with his knowledge. In the same episode, he saves a patient who has a collapsed lung. Dr. Collin is no longer a beginner and is now one of the experienced doctors. He is now married, and is often taking personal phone calls from his wife, Alison. The hospital manager Alex Legg (from series 1) makes a brief appearance, only to be killed off from a heart attack. Adrian DeVries (Jack Fortune) is the new consultant surgeon - he can perhaps be seen as this series' replacement for Mr. Betancourt. Incidentally, for the first time, the cameras move outside to show DeVries driving his car.

A young wife brings her husband in to the hospital with a suspected brain haemorrhage, and he is not expected to survive. The issue of organ transplant is raised. At first the wife says yes, but later changes her mind. David, a recurring character who needs kidney dialysis is introduced. He has a more informal relationship with Maitland, whom he affectionately calls ""slapper"". After Raj gives a patient a cigarette, the patient decides to smoke it when he is taking oxygen, and there is an explosion. A few new characters are introduced. Sarah Hudson the new consultant (it seems in place of Barry Yates who does not appear in series 3), and a new doctor is Liz Reid. Almost straight away, Liz is shown to want to dump most of her duties on other doctors and nurses as much as possible. Two elderly gentleman are brought in - one has bit off and swallowed the other's finger. Raj starts on the GP training scheme.
