99 Oxygen Saturation
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
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
NORMALLY IT WILL NOT: Drop at all.Get a more detailed answer ›
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
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
How can my oxygen saturation on my tester at home put it on it said 90% started freaking out quickly went to 97% how is this?
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
Why when I get difficulties breathing or sob, yet my oxygen saturation is 99-98%. How and what could that be. What is the symptom of low oxg saturat
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 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
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
Shortness of breath: ...Is caused by many abnormalities in the body, not simply low o2 levels. Some patients can have significant shortness of breath from copd, pneumonia, asthma and other illnesses without a low o2 level. If you continue to have trouble, you should see a doctor for evaluation to figure out why this is happening. ...Read more
O2 goes into lung: Traverse the interstitial to the blood vessel wall to the blood cells goes to tissues and be delivered. Normal saturation therefore depends on the oxygen source, healthy alveoli with enough surface area, thin and healthy interstitial and blood vessel wall and normal and adequate blood cells and healthy consumption of o2. That is the balance. ...Read more
Many: If there is underlying lung disease (such as empysema) the lung is already prone difficulty extracting o2 out of the blood. As we age our lungs and chest get stiffer and there is more unusable space- with resulting low o2. Also, central or obesity related sleep apnea can contribute to low o2 levels. Pickwickian syndrome related to morbid obsesity can also decrease the amount of o2 levels. ...Read more
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
Smoking and Oxygen: Yes. But the test is deceptive. It does not mean you do not have lung damage. It does not measure how much carbon dioxide you have or how many of your red blood cells are no longer available to carry oxygen. It just tells me that you are still young enough that you have some ability to maintain good oxygen levels despite the nineteen years of trying to damage your lungs. ...Read more
Resting oxygen saturation is 98-100 consistently. During intense exercise (85% mhr), it drops to 93-94. Is this normal?
It is fine: As long as it does not drop below 90% it is ok. You do not say what your health problems are or if you were a smoker. But it sounds like you are ok. ...Read more
Measures oxygen: Pulse ox is a technique used to measure the oxygen saturation in your blood. Oxygen is carried around the body in hemoglobin molecules; pulse ox detects what percentage of these oxygen carrying sites are being used. A normal pulse ox (at sea level) is approximately 96%-100%, meaning 96-100% of the oxygen carrying sites are indeed carrying oxygen. ...Read more
What is considered a normal oxygen saturation for a person with COPD and why is it considered normal?
Anything above 90%: > or equal to 90% is normal. This is related to the hemoglobin oxygen dissociation curve. There is a certain percentage of oxygen saturation before your cells will not let oxygen leave cell and go to tissue. That is somewhere around 88-92% so since the sensors are good only 90% + or - 2% points, we use 90%. ...Read more
Is it possible to shallow breath without hyperventilating? What affect does this have on oxygen saturation?
Mgt: Shallow respiratory cycles are associated with a number of conditions. The rate of breathing may be increased, normal or decreased depending on the condition. If you are concerned, a virtual consult may be booked online. ...Read more
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
