Here is what it says in Wikipedia about Manslaughter. It sounds about right in this case:
Constructive manslaughter is also referred to as ‘unlawful act’ manslaughter. It is based on the doctrine of constructive malice, whereby the malicious intent inherent in the commission of a crime is considered to apply to the consequences of that crime. It occurs when someone kills, without intent, in the course of committing an unlawful act. The malice involved in the crime is transferred to the killing, resulting in a charge of manslaughter.
For example, if a person throws a brick off a bridge into vehicular traffic below they could be found to intend or be reckless as to assault or criminal damage. There is no intent to kill, and a resulting death would not be considered murder, but would be considered involuntary manslaughter. The accused's responsibility for causing death is constructed from the fault in committing what might have been a minor criminal act.
In the United States, misdemeanour manslaughter is a lesser version of felony murder, and covers a person who causes the death of another while committing a misdemeanour – that is, a violation of law which doesn't rise to the level of a felony. This may automatically lead to a conviction for the homicide, if the misdemeanor involved a law designed to protect human life.
All doctors say that Propofol is not used outside of hospitals. I don't know if administering Propofol is breaking a law or a regulation, but it is clearly something that is designed to "protect human life".
