Icu doctor reported: phillips pulse ox monitors are not providing oxygen saturation data that correlates with arterial blood gas oxyhemoglobin measurement/po2.As a result, patients are inadvertently being allowed to be hypoxemic and oxygen supplementation is not being appropriately titrated up.One day, the discrepancy between pulse ox (94-95%) and abg (73%) was seen and thought to be a fluke.The patient's oxygen was titrated up.Charge nurses were notified of monitor discrepancy.The next day, the morning abg revealed a o2hgb saturation of 73.4% despite phillips pulse oximetry of 100%.Doctor discussed with the respiratory manager: rt manager advised that this problem had been identified as inaccurate pulse oximetry measurements by the phillips pulse oximetry units.According to respiratory manager, this problem had been identified previously and tracked/confirmed with concomitant arterial blood gas readings for masimo & phillips measurements and dictating that the philips pulse oximetry units have a larger margin of error compared to masimo.
