The series draws upon a documentary-style feel, including hand-held camera work for helicopter-based scenes, and detailed outlines of the procedures carried out by the medics themselves.

Thomas Sutcliffe of The Independent said that the series is composed of "wooden acting" and "cardboard dialogue", and that "the wiser viewer will realise it shows no vital signs at all".

[5] Jim White of The Independent stated that "all the characters were ludicrously gung-ho, self-important and convinced they were the only people capable of administering medical assistance; typical doctors then, but not much fun to spend sixty minutes with".

Throughout the series, the team takes on a variety of high-stakes assignments, ranging from infiltrating a drug trafficking ring to uncovering a conspiracy involving a wealthy businessman.

The series came under fire when aircraft equipment used in the filming of an episode which saw the team helping victims of a plane crash was returned to the owners severely damaged.
