Eligibility
Age
18 Years to 64 Years
Inclusion criteria
Inclusion criteria: - Patients undergoing a stomach reduction - Age > 18 - Informed consent - BMI > 28
Exclusion criteria
Exclusion criteria: - Known allergy to adhesive Ag/AgCl electrodes - Subjects who are pregnant or likely to become pregnant - Subjects with implantable devices, such as pacemaker, ICD or implanted infusion pump - Subjects using medication with with phototoxic side effects. - Tetracylines - Doxycycline - Phenothiazines - Dacarbazine - Ketoprofen - Lomefloxacin This in order to exclude the possibility of local skin irritation from prolonged irradiation by LED-light (from the activity monitor). - Patients that do not want to be informed in case of incidental findings.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| - Mean difference in measured respiratory rate/volume between ROBIN and spirometer | — |
Secondary
| Measure | Time frame |
|---|---|
| - Correlation coefficient between respiratory rate/volume between from ROBIN and spirometer - Correlation coefficient between changes in body composition and impedance amplitude (and derived parameters) - Correlation coefficient between changes activity profiles and errors in calculated respiratory rate and volume - Difference in error between electrode configuration 1 and 2 for estimations of respiratory rate of respiratory volume (see section 8.3 in protocol) | — |
