Here is the design of a clinical trial:

Official Title: Assessment of Physiological Parameters Measurements (Heart Rate, Respiratory Rate, and Oxygen Saturation) by Standard Acquisition System Compared Remote Photoplethysmography Imaging System

Included conditions:
- Plethysmography
- Remote Photoplethysmography Imaging
- Physiological Parameters

Study Armgroups:
- {'label': 'Experimental: remote photoplethysmography for physiological parameters Monitor Readings', 'type': 'EXPERIMENTAL', 'interventionNames': ['Device: Remote photoplethysmography for physiological parameters']}
- {'label': 'Control: rstandard acquisition system for physiological parameters Monitor Readings', 'type': 'OTHER', 'interventionNames': ['Device: standard acquisition system for physiological parameters']}

Interventions:
- {'type': 'DEVICE', 'name': 'Remote photoplethysmography for physiological parameters', 'description': 'physiological parameters will be acquired using the Remote photoplethysmography software simultaneously for the conventional parameters measurements (heart rate, respiratory rate, and oxygen saturation)', 'armGroupLabels': ['Experimental: remote photoplethysmography for physiological parameters Monitor Readings']}
- {'type': 'DEVICE', 'name': 'standard acquisition system for physiological parameters', 'description': 'physiological parameters will be acquired using the standard acquisition system for the conventional parameters measurements (heart rate, respiratory rate, and oxygen saturation)', 'armGroupLabels': ['Control: rstandard acquisition system for physiological parameters Monitor Readings']}

Primary Outcomes:
- {'measure': 'Concordance of rPPG heart rate readings', 'description': 'Heart rateconcordance analysis by standard acquisition system (photoplethysmography of the finger) compared rPPG', 'timeFrame': '30-120 seconds.'}
- {'measure': 'Concordance of rPPG respiratory rate readings', 'description': 'respiratory rate concordance analysis by standard acquisition system (photoplethysmography of the finger) compared rPPG', 'timeFrame': '30-120 seconds.'}
- {'measure': 'Concordance of rPPG oxygen saturation readings', 'description': 'oxygen saturation concordance analysis by standard acquisition system (photoplethysmography of the finger) compared rPPG', 'timeFrame': '30-120 seconds.'}

Please estimate the sample size based on the assumption: 
Adjustment according to age, sex, and skin phototype, and considering 10% of bad quality signals
Sample size
        With a given ICC of Ï=0.85 between the two groups of measures with a 95% CI of 0.05 width (two sided), the adjustment according to age, sex and skin phototype, and considering 10% of bad quality signals, the workforce is 1045 subjects. This number and the subjects recruited will allow a sufficiently wide distribution of values (in terms of different observed values and variety of subjects) for a good distribution of the results on the axes and thus a good estimation of the ICC.
