vi$.$ TRUE $/$ FALSE: The Doppler flowmeter transduces blood velocity into

a frequency shift between transmitter and receiver.

vii. TRUE $/$ FALSE: Partial pressure and saturation of blood gases are di$-$

rectly related to each other.

viii. TRUE $/$ FALSE: Double correlated sampling allows to remove a con$-$

stant measurement offset from a bioinstrument.

ix$.$ TRUE $/$ FALSE: Pulse oxymetry leverages the pulsative flow of blood

in the vasculature to measure both heart rate and oxygen saturation non$-$

invasively.
