Foranstaltningsbeskrivelse |
Tidsramme |
|---|---|---|
|
Noninvasive Pulse Oximetry-determined SpHb Bias
Tidsramme: Duration of study participation is up to three days.
|
Accuracy of SpHb will be determined by comparing it to the hemoglobin value obtained from a reference blood sample and calculating the accuracy root mean square (Arms) error value.
In order to obtain the Arms value, the blood sample hemoglobin value is subtracted from SpHb value for a number of samples, the average of this difference is computed as the bias.
The standard deviation of the differences is computed as the precision.
The square root of the sum of the squares of bias and precision is computed as the Arms Error value.
|
Duration of study participation is up to three days.

|
Correlation of PVI Measurement Compared With PPV or SVV
Tidsramme: Duration of study participation is up to three days.
|
Correlation of PVI measurement compared with pulse pressure variation PPV or stroke volume variation (SVV) measurement from arterial catheter
|
Duration of study participation is up to three days.
|
|
Correlation of "ORI" With Partial Pressure of Oxygen (PaO2) "PaO2" Measurement From Blood Gas Analysis
Tidsramme: Duration of study participation is up to three days.
|
Concordance will be determined by comparing the trending ability of the Oxygen Reserve Index (ORI) measurement of the sensor with that of Partial Pressure of Oxygen in Blood (PaO2).
|
Duration of study participation is up to three days.
