Are Anesthesiology Providers Good Guessers? Heart Rate and Oxygen Saturation Estimation in a Simulation Setting

Table 2

Estimation accuracy of heart rate and oxygen saturation under different recording settings.

Settings	Absolute value of heart rate difference			Absolute value of oxygen saturation
	Mean	SD	value	Mean	SD	value
Scenario A first attempt	6.2	4.88	0.0274	1.6	1.97	0.9397
Scenario B after A	21.5	10.84	<0.0001	2.1	2.49	0.3590
