-----Original Message----- From: Michael Gillet [mailto:[log in to unmask]] Sent: Thursday, 22 August 2002 1:12 To: [log in to unmask] Subject: reference ranges Do your ward based blood gas analysers print out a reference range with the patient results? Do you have reference range data 'attached' to the analyser? Mike Gillett Clinical Biochemistry Southmead Hospital Bristol Yes. They are not age related and therefore gas tensions in particular have little relevance in neonatal and delivery ward situations. They also do not apply to ventilated patients however they provide a clinically valuable assesment of acid base, electrolyte and glycemic status.
