reducing the oxygen content of each breath incrementally as one goes up in altitude. The reduction of oxygen availability in the air thus reduces the oxygen saturation in the blood and brains of unacclimatized people introduced to the environment. This is why people traveling from sea-level often...
Functionally, less oxy- gen is extracted from the blood perfusing the tissues as DO2 increases, such that venous oxygen saturation (SVO2) increases. Similarly, S v O 2 decreases as DO2 decreases over the supply-independent portion of the VO2/DO2 re- lationship. If DO2 is decreased ...
The SpO2 ranges in normal newborn infants retrieved in the first minutes after birth show that term babies achieve oxygen saturations of 70%, 80%, 90% and 95% at 1, 3, 5, and 10 min after birth while preterm babies achieve oxygen saturations of 60%, 75%, 85% and 95% at 1, 3...
We convened an expert panel to develop consensus targets for oxygen saturation (SpO2), which determined optimal range of 90–96%, partial pressure of arterial oxygen (PaO2) range of 60–100 mmHg (when applicable), and fraction of inspired oxygen (FiO2) of 0.21 for mechanically ventilated ...

Hence, SaO2 as well as SpO2 both aim to determine the functional oxygen saturation in the blood. While TPO successfully enables the continuous monitoring of sO2, the mobility of patients is still severely impaired by the finger clip—mostly cabled to the measuring device—impacting on the ...
When the patient’s breathing rate was less than 25 breaths/min after 48 hours and the percutaneous oxygen saturation was greater than or equal to 92%, high-flow oxygen therapy can be stopped. 2.6. Observation Indicators The two groups were compared for general information, including age, ...
This provides an indication of the oxygen saturation of blood and this information may then be displayed as with the use of a conventional chart recorder 26, or displayed as with an oscilloscope 28. The catheter 10 preferably takes the form of a torque controlled catheter, such as that ...
A decrease in the patient's oxygen saturation should always be a cause for alarm and may indicate a change in the patient's medical status, tachypnea, or a failure in the device. In any case, a backup system should be available in order to verify whether the problem is with the device...
