Brief summary
This study examines the effect of oxygen supplementation on the non-invasive measurement of hemoglobin.
Interventions
DEVICEhemoglobin measurement
Non invasive hemoglobin measurements (Pronto 7 device and NBM-200 device)will be made with : * at baseline (simultaneous blood sample for a laboratory measurement of hemoglobin), * with the patient breathing oxygen via a face-mask (FiO2 50 ± 5%), * with the patient breathing oxygen via a face-mask (FiO2 90 ± 5%) (simultaneous blood sample for a laboratory measurement of hemoglobin).
