Details of change.
V1.0
17/01/95
Initial release
V1.1
07/02/95
Adjustment of the offset on the HFO rate display by
2Hz., to allow for setting of the HFO rate circuit
without saturation at the top end.
V1.2
08/06/95 CN0056 Correction of error in Fail to Cycle detection
algorithm which caused spurious triggering of Fail to
Cycle alarm. Increased debouncing on “Freeze”
push button. Correction of graphic display that did

caused erroneous triggering at low pressures.
V1.5
26/03/96 CN0116 Delta P to be displayed for CPAP and HFO modes
and ident on oscillator pressure gauge changed.
V1.6
10/07/96 CN0156 Increased range of display of delta pressures.
Addition of display of pressure transducer saturation
(positive and negative).
V1.7
30/04/97 CN0308 Implementation of an HFO disconnection alarm and
pressure transducer drift alarm.
V1.8
15/05/97 CN0362 Modification of High alarm level (minimum setting).

alarm. High Delta P converted to
alarm condition. Delta P to be set as a percentage
rather than a fixed window. Reduction of the
