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 use ...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

How much does a low oxygen saturation level affect judgment?

How much does a low oxygen saturation level affect judgment?

Depends how low: Down to about 80% there isn't much effect at all at least for short periods of time. Longer periods weeks to months can have cognitive effects. Below 80% saturation there can be clear effects on judgment even for brief periods. The lower the saturation the bigger the effect. ...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
