According to the reporter, the sensor had low spo2 reading that could be seen on different monitors.It was checked with two different saturation simulators which resulted that as lower the saturation was set, a higher was the deviation downwards.Due to the incorrect readings (a high downward deviation), an unnecessary bga was performed and the sensor was change.It was reported that, due to the spo2 values seem to be very low the hcp checked this in relation to other vital signs, which all were okay.Due to these events occurred on a nicu/picu we were not able to check this again at a patient, so we used a simulator as already described.They used new sensors for investigation and the issue occurred also.Sensor placed at the patients foot and the baseline were the values when incident occurred was between 7-20% (depends on the level of saturation).Spo2 under alarm limit and was in silent mode.During surveillance of the patient; during testing with simulator, no bga data available due to data restrictions, no exact patient number.A new sensor was used and changing to a new sensor was mostly effective.There was no harm just because ot the professionalism of the hcp (spo2 readings did not match the other vital signs.

Event Description

According to the reporter, the sensor had low spo2 reading that could be seen on different monitors.The first sensor was placed at the patient's foot and the baseline values were between 7-20% (depends on the level of saturation).Spo2 was under alarm limit and was in silent mode.Due to the incorrect readings (a high downward deviation), an unnecessary arterial blood gas (abg) was performed.The second sensor was used for investigation but the issue also occurred.It was checked with two different saturation simulators which resulted that as lower the saturation was set, a higher was the deviation downwards.Third sensor was used and it worked effectively.
