As a medical professional with expertise in respiratory health, I can provide you with information on what is considered a low oxygen level. Hypoxemia refers to a below-normal level of oxygen in the blood, particularly in the arteries. When it comes to measuring oxygen levels, there are two common methods: blood gas analysis and pulse oximetry.
Blood gas analysis directly measures the partial pressure of oxygen in the blood, which is reported in millimeters of mercury (mm Hg). Values under 60 mm Hg are generally considered indicative of hypoxemia and usually suggest the need for supplemental oxygen.
Pulse oximetry, on the other hand, is a non-invasive method that estimates the percentage of oxygen-saturated hemoglobin in the blood. Normal readings for a pulse oximeter typically range from 95 to 100 percent. Values under 90 percent are considered low and may require medical attention.
It's important to note that these values can vary based on individual health conditions, altitude, and other factors. Always consult with a healthcare provider for a proper assessment and diagnosis.
