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

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

Hypoxia (Definition)

Hypoxia, is a condition in which the body as a whole or a region of the body is deprived of adequate oxygen supply. It is classified into 4 groups: - hypoxemic - oxygen is low - anemic - decreased ability for hemoglobin to carry oxygen. - ischemic - decreased blood flow. - histotoxic - oxygen is reaching the cells, but the cells are unable to ...Read more

Does bronchiolitis cause low oxygen saturation?

Does bronchiolitis cause low oxygen saturation?

It happends: Bronchiolitis causes a build up of secretions in the tiny airways and blocks transfer of oxygen into the tissues. It can and does cause a drop in blood oxygen in many cases. ...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

Does asthma cause hypoxia? What is the oxygen saturation in people who have asthma?

Does asthma cause hypoxia? What is the oxygen saturation in people who have asthma?

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

What damage does low oxygen saturation have on a childs brain?

What damage does low oxygen saturation have on a childs brain?

Depends on variables: Low saturations are a variable issue. In the womb, the baby draws oxygen from the mothers blood and during all of pregnancy, their oxygen saturation is below what we expect after their first hour of age. That said, when it is too low for the period, it forces the metabolism into a weaker method of supplying energy, starving brain cells of energy and could result in cell injury or permanent damage. ...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)

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

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

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

In a person who is elderly, what causes rises and falls in oxygen saturation?

In a person who is elderly, what causes rises and falls in oxygen saturation?

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

Does generAl anesthesia cause breathlessness after becoming concious? My oxygen saturAtion was ok but I felt breathless? Why?

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

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

Oxygen...: You don't need supplemental oxygen unless your pulse ox is less than 88%. Most healthy 35 year olds have an oxygen saturation of at least 95% but there can be many reasons for having an oxygen sat in the lower 90's including being overweight, bronchospasm, gerd, etc. So, if you are short of breath or if your oxygen sat is persistently in the low 90's, see your doctor for evaluation/treatment. ...Read more

In a person with sleep apnea, what causes the rises and falls in oxygen saturation of arterial blood during sleep?

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

Its hard for me to breathe. I get really bad headaches. Like all the time. And its really hard for me to remember stuff. Possible low oxygen levels?

Possibly: Difficulty breathing and headaches are potentially serious symptoms. I would get into your primary care as soon as you can.

Is it normal for healthy person to have low oxygen on flight? Dipped down to 91-89 on my last flight and had a headache. Worried about undiagnosed PE.

Stop: Why are you checking your oxygen on a flight? If it constantly stays below 89 for more than 5 min AND you feel short of breath, have chest pain, or pain and swelling in your legs then start to worry and see a doctor. Portable pulse oximeter readings bounce around all the time- it is usually from motion artifact and not a true reading. Try browsing the in-flight magazine to pass the time... ...Read more
