SpO2 and SpHb Measurements During Patient Motion
Pronto displays measurements of SpO2 and may display SpHb during patient motion.
However, because of the changes in the physiological parameters such as blood volume,
arterial-venous coupling, etc. that occur during patient motion, the accuracy of such
measurements may not be reliable during excessive motion. In this case, the Low SIQ
indicator illuminates to alert the clinician that the device does not have confidence in the
value displayed due to poor signal strength caused by excessive motion or other signal
interference. For more information, see
Low Signal I.Q. (Low SIQ)
on page 40.
