The oxygen level that they hospitalize you is when your blood oxygen level drops to 88% or lower.
Oxygen levels between 91% to 94%, require you call a doctor or visit an urgent care center and oxygen levels between 95% to 100% are normal.
An oxygen level between 88% to 90% is concerning and you should seek prompt medical attention.
If your oxygen level drops below 88%, it's dangerous and you should go to the nearest hospital ER right away.
Emergency signs of low oxygen levels include, blue lips or blue fingers, severe trouble breathing, chest pain or even confusion.
If you have illnesses like COPD, your blood oxygen level may normally run lower at between **% to 92% under a doctors care.
And before testing your oxygen level, warm your hands and if you wear nail polish remove the nail polish and sit still before retesting your oxygen levels, especially if you get a low reading.
The lowest oxygen level before death is any oxygen level below 80%.
When it comes to blood oxygen levels, there's no single exact blood oxygen level that causes death, because the body can shut down at varying percentages of oxygen levels depending on a persons overall health.
Although, normal oxygen levels are 95% to 100%, and oxygen levels below 80% to 85% cause critical organ distress, and oxygen levels that drop into the 70s or lower percentage often signal a persons final hours or days of life, although pulse oximeters can also become inaccurate at very low oxygen level ranges.
A 95% to 1005 oxygen level reading is normal, healthy blood oxygen range.
A 90% to 94% oxygen level reading is mild low oxygen or (hypoxia), in which the body tissues still function, but also need monitoring.
A 80% to 89% oxygen level is a dangerous oxygen level, which causes confusion, extreme shortness of breath, and even potential brain injury.
And a oxygen level that is below 80%, is critically life threatening, as severe risk of organ failure as well as cardiac arrest can occur.
And skin discoloration and major cognitive loss often happen when the blood oxygen levels are in the 60s and 70s.
In natural end of life or hospice transitions, oxygen saturation also frequently drifts downward as the persons breathing slows, which is a normal part of the dying process, instead of an acute emergency.
Also most standard finger pulse oximeters fail to read accurately or lose signal entirely when the oxygen saturation falls below 80%, or when a persons circulation drops near death.
