PI is determined from the pulsatile part of the plethysmographic curve, with typical values measured on the fingers ranging from 0.02% to 20%. Although PI is a relatively newly measured parameter, it has already found application in many areas of clinical medicine. It can be used as an indicator of the severity of health status in different groups of critically ill patients, e.g. in patients with sepsis, in patients after cardiac arrest, for early detection of critical heart defects, for indirect assessment of patient pain, as an indicator of fluid therapy and reactivity, or for assessment and evaluation of anaesthesia in the operating room. However, there is currently no standardised calculation of PI and different manufacturers use different algorithms for the calculation. The consequence is that absolute measured values cannot be compared between devices.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Healthy Adult Volunteer\n\nExclusion Criteria:\n\n* Post-traumatic upper limb conditions affecting finger perfusion\n* Injuries or diseases of the skin of the fingers\n* Any acute phase of any disease'}, 'identificationModule': {'nctId': 'NCT06635018', 'acronym': 'PICOMP', 'briefTitle': 'Effect of Pulse Oximeter Device on Measured Perfusion Index Values', 'organization': {'class': 'OTHER', 'fullName': 'Czech Technical University in Prague'}, 'officialTitle': 'Effect of Pulse Oximeter Device on Measured Perfusion Index Values', 'orgStudyIdInfo': {'id': 'NVT_01_2024'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'Determination of effect of pulse oximeters from different manufacturers on measured Perfusion index', 'description': 'Three finger pulse oximeter sensors from different manufacturers are placed on the middle fingers of one hand.
