Design outcomes

Primary

MeasureTime frame
The accuracy of the Sonde predictive algorithm to predict when antibiotics will be required to treat an acute pulmonary exacerbation. This will be from the sensitivity and specificity of the predictive algorithm when compared to the Project Breathe predictive algorithm over a 12-month period.

Secondary

MeasureTime frame
The accuracy of the Sonde predictive algorithm to substitute for spirometry and pulse oximetry. This will be from the sensitivity and specificity of the Sonde predictive algorithm when compared to spirometry and pulse oximetry over a 12-month period.
