The Oasys Computer Program

Oasys-2 is a computer program that plots and interprets serial peak expiratory flow (PEF) readings of patients suspected as having occupational asthma or work-related asthma. Oasys-2 uses a discriminant analysis to score the record between 1 and 4 using a cutoff of 2.5. Scores above this have a 94% specificity for occupational asthma and a 75% sensitivity when using independent methods of diagnosis. Oasys-2 is not yet commercially available. To obtain a beta release of Oasys-2 please email us from the Contacts page. There are two other flavours of Oasys, Oasys-3 and Oasys-N, but these have not been independently validated as yet.

Oasys discussions

You can comment on the latest Oasys question:

I wonder if you can help me. I have successfully entered data for a patient and produced reports. However, I have realised that the first set of readings (which were form 2004 and never analysed) need Miller Correction. However, when I have tried to edit the record, the icon is not available nor are any relevant drop down menu choices. I tried creating a new record to adjust from the beginning but with the same problem.
