Should I have received Communion and anointing from an Orthodox priest?

The Sacraments

The short answer

Yes, that was permissible. A Catholic may receive these sacraments from a validly ordained non-Catholic priest, such as a Russian Orthodox priest, when no Catholic priest is available and there is necessity or spiritual benefit — as for a Catholic in hospital.

What canon law allows

A Catholic may receive these sacraments from a validly ordained non-Catholic priest, such as a Russian Orthodox priest, when he has no access to a Catholic priest and there is some necessity or spiritual good involved (see CIC 844).

Your situation

A Catholic in hospital without access to a Catholic priest qualifies.
