Here’s How Oxygen Is Moved Through the Heart and Lungs to the Body: A healthy, normal blood oxygen level remains around 95 percent to 100 percent. You can monitor your blood oxygen level at home with a pulse oximeter. Values below 90 percent are considered low. When your body doesn’t receive enough oxygen and you have a low blood oxygen In reply to Zebrina's comment. He has the 100% saturation at room air-no oxygen yet. I just read that it is bad as it causes tissue level O2 drop (due to low CO2, although hemoglobin is saturated, can't release the oxygen to the tissues) that can lead to pulmonary hypertension and all sorts of other problems. The fix is more oxygen! Your blood oxygen saturation is a measure of how much oxygen is in your blood. A normal blood oxygen reading is generally considered to be 95 to 100 percent.A lower reading can indicate an
Oxygen saturation is an essential element in the management and understanding of patient care. Oxygen is tightly regulated within the body because hypoxemia can lead to many acute adverse effects on individual organ systems. These include the brain, heart, and kidneys. Oxygen saturation measures how much hemoglobin is currently bound to oxygen
Sometimes low oxygen saturation levels are related to high carbon dioxide levels. This can impact your SpO2 readings in two ways. First, when your body can't adequately dispose of this waste gas or is exposed to high amounts of carbon dioxide, it builds up in the blood and interacts with water to form carbonic acid. 3. Gasping for air. 4. She describes it as a sinking feeling in her chest. 5. She feels extremely tired after such episode. After an hour or so, her oxygen levels goes back to around 93-95. During such an episode, deep breathing helps in raising her saturation to 95 but drops to mid 80's once she resumes normal breathing. In 1949, Davies and Mackinnon [] described oxygen-induced neurological symptoms in patients with cyanosis due to emphysema with chronic cor pulmonale.After encountering two such cases, including one with a fatal coma, the authors set up a study to examine the effect of oxygen on intracranial pressure (that is, cerebrospinal fluid pressures measured through a lumbar puncture) in similar patients.
The only true reading of actual O2 saturation is blood gas. Optical O2 sensors only measure hopoglobin saturation (usually oxygen) but could be something else (CO is the biggest false positive, but IV dyes and high billiruben can cause false lows also). Any ABG's done? Sounds like it was a trying patient for the staff though.

SpO 2 rose only to 86% while breathing 7 L/min supplemental oxygen via nasal cannula. Other vital signs were normal (blood pressure 124/68 mm Hg, heart rate 86 beats/min, respiratory rate 16/min) and the patient showed no signs of respiratory distress. Physical examination revealed normal breath sounds without any signs of heart failure.
