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

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

Oxygen saturation was 92% this morning when I first woke up is this normal?

No: 92% is not severely abnormal but is abnormal for someone who is otherwise healthy and as young as you. Note that pulse oximetry is not perfect technology, however, and may not always be accurate. ...Read more

I have a at home oxygen saturation tester and I put it on it said 93% but went to 95 %?

O2 sat: Hi, why are u checking ur O2 sat at home, do you have a lung condition that you are on Oxygen? If your hand is cold or the skin is oily, nail polish, hand movement, strong light around and etc cause the sensor not to work properly and gives an inaccurate result. ...Read more

How is oxygen saturation defined, i.e., what is it? And what does a value of 85 mean?

Safe is > 90%: Oxygen saturation is the % saturation of arterial blood with oxygen. Normal for people without lung or heart disease is usually greater than 95%. 85% is too low. If you have an oxygen saturation of 855 you need to see a doctor immediately even if it means going to Emergency. ...Read more

I have an oxygen saturation reader at home I put it on it said 92% but within Five seconds went to 97% and staYed at 97% why is this?

Normal.: Because the machines are not always precise or accurate. They can be misled by a variety of factors. Don't use the meter to check your pulse either. They generally measure for 6 seconds and multiply by ten so that pulse seems to vary wildly. ...Read more

What does "oxygen saturation of hemoglobin" mean?

Oxygen Saturation: Red blood cells contain protein called Hemoglobin. Most of the oxygen in the body is attached to the hemoglobin. Oxygen saturation refers to proportion of red blood cells whose hemoglobin is bound to oxygen. It can be measure by pulse oximetry or by sampling blood from an artery. ...Read more

Are oxygen saturation levels lower in the elderly?

Not necessarily: As we age, it may get a little harder for the oxygen to get into the blood through your lungs. But, as long as you have healthy lungs, the oxygen saturation levels can be normal well into one's 80s or 90s. ...Read more

Oxygen saturation 95% pulse 65 should I be worried?

Are you sick?: Any measured finding has to be correlated with your condition. If you feel fine, then these values are okay. Do you smoke? If you feel bad: have shortness of breath, cough, fever, chest pain, etc. And if you repeat them and the numbers are the same, then you should get seen quickly. Either value can be normal, or indicate a problem, depending on what is going on at the time you measure them. ...Read more

Is oxygen saturation in room air the same thing as spo2?

Yes, generally: Speaking. Spo2 refers to any oxygen saturation obtained by using pulse oximetry, the type of absorption spectrophotometry - that is why "p" is added. It will reasonably accurately show the percentage of oxygenated hemoglobin in the individual's blood at the wide range of inspired oxygen concentrations - from room air to a 100% o2. ...Read more
