Occasional sex scenes but these are very brief and lack in nudity or detail (i.e. thrusting).

Occasional moderate sex references.

Some stories depicted may involve themes such as rape.

Operations on people are shown every episode. These are often graphically detailed and realistic.

Many of the operations result in death or impairment. This is often very disturbing.

Sometimes accidents in the show happen to vunerable people (i.e. Old people, pregnant women)

Mild profanity and swearing sometimes sometimes; nothing particularly strong.

Drugs are used non-graphically in some medical situations.

Sometimes illegal drugs such as MDMA are taken but usually these episodes have a strong anti-drug message and the negative effects of drugs are shown. Also drugs are usually only taken by unsympathetic characters.

A principal character regularly smokes.

In most episodes an incident happens towards the beginning (a boy falls off a motorcycle etc). These can be frightening or intense.
