How does OASYS work?

OASYS Score Chart

OASYS consists of the following modules:

  • A module for allowing entry of PEF readings recorded by the patient for either manual entry of PEF data or automatic capture of PEF data from the Vitalograph asma-1 usb respiratory monitor
  • A module to plot these recordings in a graph format. These graphs include a plot of mean PEF for each two hour period separated into work/rest days and plots of daily maximum, minimum and mean readings again divided into work and rest periods
  • A module to calculate scores indicating how likely it is that an occupational asthma diagnosis will be supported by this data
