What Causes Oxygen Saturation To Drop
Will panic normally cause sudden drop in oxygen saturation levels? With sudden pulse of 144, oximeter went from 95% to 83%. Is that a normal reaction?
Not normal!: I don't know of "normal" reactions to panic. But something was not right to have those vital sign extremes. See a doctor to for an exam and report those stats. A feeling of panic can be a symptom itself, especially if there was no environmental or pre-cursor emotional horror to cause it. If your cardio system is ok, get a referral to a psychotherapist w/ excellent anxiety-panic tx skills. Best wis. ...Read more
NORMALLY IT WILL NOT: Drop at all.Get a more detailed answer ›
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
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
Typically no: Typically no unless the stroke affects breathing. ...Read more
No: No, there is no correlation.Get a more detailed answer ›
It can: Asthma can reduce the area of the lung available for co2/oxygen exchange and can do so with variable intensity during an asthma attack. Given a normal o2 % of 94-100, I have seen levels below 50% recorded but patients are usually quite symptomatic below 90%. When an attack is passed and the patient relaxed, the levels return to normal with work of breathing decreased to normal. ...Read more
When I get warmer my oxygen saturation drops as low as 85 - 93% and is harder to raise. Why is this? (also become tired with headaches at rest)
Since I don't have: ...any clinical information, I must give general info only. O2 saturation may drop at higher body temperature b/c the metabolic rate may also increase. This can, in theory, increase the demand for O2, causing a relative mismatch between O2 supply & O2 need. Fatigue & headache are common symptoms of a low oxygen level. Symptomatic hypoxemia requires medical evaluation & monitoring. Dr. Anne. ...Read more
Does generAl anesthesia cause breathlessness after becoming concious? My oxygen saturAtion was ok but I felt breathless? Why?
Muscle blockade....: With general anesthesia, neuromuscular blocking agents are often used to paralyze the muscles during the surgery. Sometimes it takes a little while for these to completely wear off. Your respiratory muscles can be affected so you are not taking real deep breaths. This can lead to the feeling of breathlessness. When the melds wear off, you feel normal again. That may be the reason for your symptoms ...Read more
Is it normal for oxygen saturation to sharply drop when deep breathing/hyperventilation stops? Patient's SPO2 can drop into 80% region
My daughter has bronchiolitis and her oxygen saturation today fell to 92. After receiving several meds via nebulizer and her vein. Cause?
Mismatch: Between areas in the lungs where the oxygen can get through constricted airways and those parts of the lung tissue where the most of the blood is circulating creates the drop in percentage of oxygenated hemoglobin (saturation). 92% is worrying, but if it does not drop any further, is not life-threatening in a 15 months old, as long as there is prompt access to care and adequate monitoring ...Read more
Please tell me a list of causes for air hunger/sob when your oxygen saturation is 100%. Can you still have pulmonary emboli with 100% oxygen saturatio?
SOB: Saturation when oxygen is above 60 torr can range from 90-100%. Pe can be large or small. Air hunger can be when there is real causes as in pneumonia, asthma, pe or even when a lung is constricted and can't inflate fully and lacks the feeling of satisfaction, anxiety, nervousness, CHF or even simple cold with congestion can do it. It is best to talk to your doctor, he/she knows you better than us. ...Read more
In a person with sleep apnea, what causes the rises and falls in oxygen saturation of arterial blood during sleep?
Sleep apnea: Sleep apnea is defined as stopping breathing for 10 seconds. During that time, the body is not getting any oxygen. In addition, there can be instances that last less than 10 seconds, or where a less than adequate effort to breath is attempted. These also reduce the oxygen intake. ...Read more
Oxygen saturation drops to 83 to 87 when my new born baby sleeps. Lungs X-Ray and eco screening has shown normal study. What would be the reason.
Birth History?: Are you testing your baby's oxygen level at home? How many days old is the baby? Was the birth vaginal? Were there any complications? What was the birth weight? How is the baby feeding? How frequent are his stools? Does he show signs of respiratory distress? Does he have a heart murmur? The answer to your question definitely depends on all of the above answers! ...Read more
With congestive heart failure or coronary ischemia would the oxygen saturation shown on the monitor at hospitals drop?
What would cause shortness of breath and pain in left breast chest CT scan normal X-ray normal abg normal EKG abnormal oxygen saturation normal?
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
