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 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 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

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

Does the low oxygen saturation experienced on a commercial flight have a negative effect on a baby's developing brain?

Heaven forbid!: Can you imagine the class action lawsuit on that? And what about anyone else with chronic lung disease? No worries. The cabins are pressurized and oxygenated. If that is disrupted, that masks pop down. Air travel is much safer than the highways. ...Read more
