Oxygen Saturation (Overview)

Oxygen saturation is a measure of how much oxygen the blood is carrying as a percentage of the maximum it could carry.

What is oxygen saturation (spo2) while sleeping that is dangerously low?

What is oxygen saturation (spo2) while sleeping that is dangerously low?

It all depends: Without knowing a detailed medical history to determine if "low" oxygen may be a chronic, well compensated issue, it is impossible to answer. Typically normal oxygen staurations are within 94-97% while sleeping. Patients with sleep breathing disorders, like sleep apnea may experience dips in this saturation. However, it is standard to try and keep saturation above 89%. Talk to your doctor. Read more

Is an oxygen saturation of 69% when sleeping dangerously low?

Is an oxygen saturation of 69% when sleeping dangerously low?

Yes: 69% saturation is quite low. Does the patient stop breathing at night (sleep apnea)? Do they have copd? Asthma or other lung disease? These questions need to be answered. The primary care physician should be consulted and a sleep study ordered. Read more

Why do I get daily attacks of shortness of breath when my peak flow, oxygen saturation, pulse, temperature, blood test and EKG results are all normal?

Why do I get daily attacks of shortness of breath when my peak flow, oxygen saturation, pulse, temperature, blood test and EKG results are all normal?

Breath: Many things can cause you to feel short of breath. One of the most common is a panic attack. Are you prone to them? Other medical conditions such as congestive heart failure with volume overload are frequently seen in elderly patients. Other heart conditions and pulmonary conditions can cause this as well. In a young healthy person such as yourself a panic attack seems more likely. See your Dr Read more

What common medical conditions are associated with low oxygen saturation levels?

Lung & Heart Disease: Hypoxia (low oxygen saturations) are usually caused by lung disease (chronic obstructive pulmonary disease, asbestosis, pulmonary fibrosis, etc). Many heart conditions (especially congenital defects in the new born) may result in low oxygen saturation levels. Beware of false lows with pulse oximetry readingson cold hands, peripheral vascular disease or really callussed finger tips. Read more

Please help docs! Is oxygen saturation the same things as oxygen uptake?

Not quite: Oxygen saturation reflects the proportion of red blood cell pigment - hemoglobin that is loaded ("saturated") with oxygen. It is unitless and shown as %. Oxygen uptake is the quantity of oxygen absobed/ consumed per unit time, usually in milliliters per min. Read more

With an av canal defect what is the normal? Oxygen saturation levels in an infant?

Depends: Av canal defects are a cluster of seperate defects. The oxygen saturation would depend on which defect is present and to what degree. Read more

How do I get my oxygen saturation level up?

How do I get my oxygen saturation level up?

Several factors: Several factors determine oxygen saturation. These include the amount of oxygen you breathe, the ability of the lungs to extract oxygen, the amount of red cells to carry oxygen, the ability of the heart and blood vessels to deliver oxygen to tissues, and efficiency of organ to use oxygen, any problems affecting these can cause low saruration. Treating a disease, exercise, supplemental o2 may help. Read more

What symptoms would 72% oxygen saturation cause?

What symptoms would 72% oxygen saturation cause?

Not good ones: 72% sat is usually associated with confusion or general decrease in mental status and often difficulty breathing. If none of the above, check the equipment, otherwise seek emergency care. Read more

I'm 18 & my oxygen saturation is 95. Is this bad?

No: Any oxygen saturation above 90% is ok, but most healthy people have oxygen sats between 95-100%. But, even being 94% can be normal. Oxygen saturation varies minute to minute, so one simple measurement may not give the whole picture. Moreover, pulse oximetry can be notoriously inaccurate, so make sure the measurement is truly accurate. But, in general, 95% saturation is great. Read more

Why does oxygen saturation go down when using a bpap?

It should not.: If the machine is calibrated and operated correctly and the mask is fitted correctly, then your o2 saturation should be improved. It sounds as though you need a tune up at your doctors office or by you sleep tech. Read more

Are there any medications that can negatively effect oxygen saturation?

Yes: The sulfa medicines that we give IV can affect the saturation of hemoglobin or a discordance of the saturation meter and the blood gas, and so can nitroprusside that we use in the intensive care and carbon monoxide poisoning. Read more
