It’s a quick and harmless way to check if someone’s blood oxygen level is too low. Healthcare providers use pulse oximeters frequently in hospitals. WebMost pulse oximeters are accurate to within 2% to 4% of the actual blood oxygen saturation level. This means that a pulse oximeter reading may be anywhere from 2% to 4% higher or lower than the actual oxygen level in arterial blood. A number of factors can impair the functioning or accuracy of a pulse oximeter. daily news sin city
