Any level below this is concerning and in need of immediate medical attention since it means your organs tissues and cells arent getting.

Does shallow breathing mean death is near. A normal ABG blood oxygen level for healthy lungs will usually fall between 80 and 100 millimeters.

In medical shorthand you may hear it called a PaO 2 when using a blood gas and an O 2 sat SpO2 when using a pulse ox. Low blood oxygen levels can impede all of these activities and more.
