"Clinicians see discrepancies in the readings when they compare the cheaper home pulse oximeter to the ones used in the hospital."

Oximeters used by EMS professionals should work for all  patients, even those with low perfusion and hypoxia. 

Does using an inferior oximeter put your department at risk?

Clinimark Laboratories, an independent hypoxia lab, was asked to investigate the performance of two newer fingertip pulse oximeters and the Nonin Medical fingertip pulse oximeter during dyspnea and low perfusion. Multiple hypoxic events down to the 70–85% range were induced to verify that the pulse oximeter was able to track saturation changes during these challenging conditions.  In order to do this in a repeatable, safe manner this study was conducted in a laboratory setting by creating dyspnea, low perfusion and hypoxia in healthy volunteer subjects. The study found that the low cost oximeter gave false readings in 9 out of 12 subjects having low perfusion with labored breathing.

Only Nonin pulse oximeters have PureSAT®pulse oximetry technology, which is precise enough to measure the oxygen level from each pulse. Many other finger pulse oximeters for sale need to calculate an average oxygen level across numerous pulses, which often results in delayed or inaccurate readings.
