Arms/Interventions Module

Label	Type	Description	Intervention Names
surgical patients	Experimental	patients studied just before induction of anesthesia	Device: hemoglobin measurement

Interventions

Name	Type	Description	Arm Group Labels	Other Names
hemoglobin measurement	Device	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).

Outcomes Module

Primary Outcomes

Measure	Description	Time Frame
influence of the inspired oxygen fraction on the noninvasive measurement of hemoglobin (Pronto 7 and NBM-200 devices)	Statistical comparison of the 3 measurements (baseline, FiO2 50%, FiO295%) for each device	one year (end of the recrutement period)

Secondary Outcomes

Measure	Description	Time Frame
agreement between the noninvasive methods of measurement of hemoglobin and the laboratory analysis	Statistical comparison of the 2 devices	one year (end of the recrutement period)
