Example monitoring protocol for monitoring health status and recovery in operable lung cancer patients. Abbreviations: SpO2 = blood oxygen saturation. Context: Patients wear the monitoring system, 3 days a week, during 2 weeks pre-surgery, the first month post-surgery and 2 weeks prior to the doctor consultation at 3 and 6 months post-surgery. The system monitors 1) physical activity level during the entire day, 2) heart rate and blood oxygen saturation during 30 minutes of rest and 30 minutes of increased physical activity. Sensors for these measurement are placed and removed by the patient themselves. Directly following these periods of rest and increased physical activity the patients rate their pain, fatigue and dyspnea on a 0-10 visual analogue scale.
