Pulse Ox Reading
Does having an elevated cohb (nonsmoker) cause a false normal pulse ox reading? Also methb & o2/g hb are on the highest sides of normal. Hb & oxy are ok
Carbon monoxide: If you are exposed to carbon monoxide from wood stoves or other sources you can have a high level in your blood. Co binds tighter to hg than o2 so the pulse ox is only an estimate based on normal parameters. I suggest a co moniter/ alarm for safety. ...Read more
Around 95%...: Between exacerbations, an asthmatic's pulse ox is normal since airway obstruction in asthma is reversible by definition. During an asthma exacerbation, the airways are obstructed/inflamed to a certain degree depending on the severity of the exacerbation and the pulse ox may decrease. Supplemental oxygen may then be necessary to maintain oxygen delivery to vital organs/tissues. ...Read more
Working out and changed lifestyle to lose weight. Doc says I need sleep study due to overnight pulse ox reading. Should I be scared?
No: No and congrats on lifestyle changes. A sleep study is a diagnostic aid in helping to determine sleep apnea and if it is mild, moderate or severe. No need to have anxiety. If you are anxious, it may make the sleep study less effective because you may not be able to sleep to help the sleep lab get accurate readings. ...Read more
I've had three pulmonary embolisms in the past and just got diagnosed with pneumonia. My pulse ox is reading between 88-93. That normal?
Normal oxygen Saturation Should be above 90%
It is normal with Pneumonia pending on severity to have lower oxygen saturation
If You have had 3 Pulmonary Embolism You should be in long life anticoagulation and may need a V/Q Scan and ECHO To make sure you don't have chronic Pulmonary Hypertension and Chronic thromboembolic Disease. You may need To wait for Pneumonia resolution. ...Read more
95-100%: In normal healthy patients with normal lungs and hearts, pulse oximetry doesn't start to really drop until the anaerobic threshold is reached, and that only happens during very intense exercise. But be careful - pulse oximetry readings during exercise are problematic due to motion artifact and altered perfusion in the fingers (where it's usually measured). ...Read more
Most are similar: Most commercially available retail pulse oximeters use the same technology, and cost difference occur from size, portability, and additional features. If you are purchasing a pulse oximeter for home use using you own funds, consider a low-cost fingertip oximeter, such as the ones available at large online retailers for under $50. ...Read more

On my S Health phone app pulse ox measures 93 repeatedly. Concerning? I'm 60 and female, moderately active.
WITHIN NORMAL LIMITS:
AS LONG AS YOU AREN'T SYMPTOMATIC, I WOULDN;T WORRY ABOUT IT. IF YOUR SATURATION DROPS WHEN YOU ARE EXERCISING GO TO THE DOCTOR AND HAVE IT CHECKED OUT ON A MORE CALIBRATED DEVICE.
NO TREATMENT IS INDICATED FOR OXYGENATIONS ABOVE 92. ...Read more
Pulse ox seems to start out a little low, like 96, when first measured, but fixes itself within 5-10 seconds. Concerning?
32 yr old f. I used bp cuff and my readings were bp= 89 over 66, pulse= 120, pp= 23. Should I be concerned with the pp reading so low??
No: The pulse pressure is considered low if it is less than 25% of the systolic BP. So your pp is normal. ...Read more

First, Is person currently acutely ill with cough/ Upper respiratory Infections/ Pneumonia or muscle strain/injury that restrict full lung expansion and deep breathing. 2nd, does one Smoke cigarettes or other items.

My normal oxygen level us 96-98 on a pulse ox, I traveled to new Mexico and it was 91-95 and I didn't feel well? Why the drop in oxygen?
Interesting: I wonder if this has something to do with atmospheric change, but would have to know where you originate from. I'm also curious as to why you measure your oxygen level regularly. Is there a health product for this? The lower O2 level could be a cause of not feeling well or an effect of something else that made you not feel well (eg pneumonia). Recommend virtual c/s for more informed response. ...Read more
If I was having true resp failure would I have a normal rr or increased? And would my pulse ox be abnormal? Rr currently 11 and shallow/sob
Pulse ox: In Respiratory failure you can have increased rr or decreased rr depending on the cause of respiratory failure. It basically means that your are not making enough oxygen to maintain oxygen in the blood. Your lungs could react by increasing the rr first to compensate but then they tire out and the rr goes down (worse situation). ...Read more
Vision seems dim when reading words, not any other time. When I look at words fuzzy until I blink. Sides of my head pulse thoughout the day but no pain.
60-100 bpm.: Assuming the underlying heart rhythm is normal, a heart rate between 60 and 100 bpm would be considered normal at rest. Would go above 100 temporarily with activity, and may be under 60 at rest in someone who’s athletic. If this is your resting HR, it’s too high and deserves investigation. ...Read more
What level?: To what O2 sat did your sat drop to, if it was ...Read more
I have 2 pulse oximeters. How do I know which is correct if they both give different readings? (e.g. 96% on one, 89% on the other!)
One might be wrong: Two pulsoximeters - one reading 96% and one reading 89%, indicating one probably wrong. Not sure what your home pulsoximeter is for, but if you are having symptoms of shortness of breath, wheezing, coughing, chest tightness, please see your physician right away. 96% is pretty normal, 89% is not. ...Read more
What could cause low pulse ox n high hr in a 65yo with clean test results apart from high sugar? Non smoker but did smoke for 25years
Nobody here can say: The damage from smoking never really heals. The history and physical exam are far more important than the labs. While the smoking history and the age would be enough to lower the pulse ox, the big picture needs to be considered as well. ...Read more
What could cause low pulse ox n high hr in 65yo non smoker with clean test results? O2 sit around 85-89 hr 110-140 1yr ago all was normal
Needs explanation: Either lung or heart disease or a combination of the two can be contributing. If your pulse ox meter is correct you should see someone and get a diagnosis. ...Read more
If you have regular BP and pulse readings - if CAD develops will BP/P be affected so after taking a regular reading they know to invesigate further?
No: CAD generally will not affect heart rate or blood pressure, so development of abnormal heart rate or blood pressure is not thought of as a clue that CAD has developed. Clues that CAD have developed are abnormal ECG, shortness of breath with exertion, chest pain / jaw pain / arm pain with exertion, fatigue with exertion. ...Read more
Short of breath: Pulse oximetry measures the amount of oxygen getting into the blood. A process which causes respiratory work or comfort to be problematic but which allows for adequate oxygenation of the blood like chest wall pain, some muscular problems and mechanical problems with breathing could cause the finding. ...Read more
Your BP Is in the: Low normal range (normal BP 100-140/ 60-90) and your heart rate is slower than the average (60-90). Ask ur dr if he would consider cutting down on the dose of your metoprolol.
