Diffuse optical spectroscopy (DOS) Channel 1 (top) and Channel 2 (bottom) coefficients of determination for all 10 subjects. During REBOA, DOS parameters in Channel 1 associate with systemic parameters while Channel 2 is not.

Channel 1 Coefficients of Determination (R²)

	Hemorrhage			REBOA
	MAP	HR	SV	MAP	HR	SV
HbO₂	0.76^*	0.69^*	0.65^*	0.83^*	0.82^*	0.92*
HbR	0.79^*	0.88^*	0.82^*	0.40	0.69	0.43
StO2	0.79^*	0.72^*	0.68^*	0.82^*	0.82^*	0.92*

Channel 2 Coefficients of Determination (R²)

	Hemorrhage			REBOA
	MAP	HR	SV	MAP	HR	SV
HbO₂	0.89^*	0.91*	0.90*	0.06	0.01	0.03
HbR	0.61^*	0.46^*	0.49^*	0.38	0.62	0.14
StO₂	0.88^*	0.88^*	0.88^*	0.01	0.06	0.00

The asterisk (*) is used to denote if the relationship is statistically significant (P<0.05). Cases with high coefficients of determination (R²>0.90) are displayed as bolded text.

(Note: HbO₂ = Oxyhemoglobin; HbR = Deoxyhemoglobin; StO₂ = Hemoglobin oxygenation saturation; MAP = Mean arterial pressure; HR = Heart rate; SV = Stroke volume).
