What is it indicated for?
The Sigma Delta 'T' vaporizer range is designed to attach to the back bar of an anaesthetic machine and deliver controlled concentrations of anaesthesia gasses into a fresh gas. The fresh gas is then delivered into a patient breathing system, from where the anaesthesia ventilator and breathing circuit will then deliver this fresh gas mixture to the patient.
The Vaporizer is calibrated in Vol % of the fresh gas flow and is compensated for changes in both fresh gas flows and temperature changes within the specified range.
The indicated use of the Sigma Delta 'T' has therefore not changed from that of the legally marketed device the Sigma Delta.
Indications for use as stated in the FDA 510(k) statement.
