Are oxygen saturation levels lower in the elderly?

Are oxygen saturation levels lower in the elderly?

Not necessarily: As we age, it may get a little harder for the oxygen to get into the blood through your lungs. But, as long as you have healthy lungs, the oxygen saturation levels can be normal well into one's 80s or 90s. ...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

Arterial blood gases, very low oxygen levels found in m y newborn?

Transient issue: Fetal o2 generally runs low levels while they extract it from mom with the placenta but it is adequate for their needs. During the transition of labor & delivery it continues to remain low ~70 & generally will not come up to regular levels (95+) for several minutes or hours after birth.Scalp abg's @ birth document stress, but are less important than babies vigor & breathing effort @ delivery. ...Read more

Is an oxygen saturation of 69% when sleeping dangerously low?

Is an oxygen saturation of 69% when sleeping dangerously low?

Yes: 69% saturation is quite low. Does the patient stop breathing at night (sleep apnea)? Do they have copd? Asthma or other lung disease? These questions need to be answered. The primary care physician should be consulted and a sleep study ordered. ...Read more

What causes low oxygen levels in the elderly?

Other diseases: If you ask me what causes low o2 in a perfectly normal and healthy elderly it makes a difference. There is an alveolar to arterial ratio that changes with age, and o2 is lower in elderly by this notion alone but no to point of hypoxia. There is such thing as senile emphysema by age alone, with the changes like that of the skin. See the compressibility of finger as the machine could restrict pulse. ...Read more

Why are hemoglobin levels higher in newborns?

Why are hemoglobin levels higher in newborns?

To carry more oxygen: Fetal hemoglobin hangs on to oxygen tighter that adult hemoglobin. Therefore more red blood cells are needed to cary the amount of oxygen that can be delivered to the tissues. The blood in utero is very saturated at a lower oxygen tension. The fetal hemoglobin is needed in utero and is slowly replaced by adult hemoglobin after birth. ...Read more

For blood oxygen saturation level - what is the fatal and normal range?

Oxygen sat curve: If you look at the p50 or oxygen saturation curve, anything above 90% is ok for the hemoglobin to unload as it gets into the tissues and supply them. As the curve goes down to 75% about pao2 of 45, this nears the saturation in the veins where unloading of oxygen to the tissues including heart muscles becomes difficult and there will be eventual death as it gets lower than that. ...Read more

Does sepsis usually cause oxygen saturation levels to fall?

Does sepsis usually cause oxygen saturation levels to fall?

It can: Sepsis can cause acute inflammation and swelling in the lungs making it harder to breathe, and causing oxygen levels to drop. Compromised heart and kidney function, as well as fluid resucitation can make matters worse. ...Read more

Causes for low oxygen sats93-97%?

Many possibilities: With a proper medical history one might make some good guesses. That along with a proper physical exam might help better explain. Blood work could possibly even help. Not uncommonly it is a combo of things age included. Generally, it is not a major issue as long as it remains above 90, but still if there has been a sudden change it warrants looking into further. ...Read more

Arterial blood gases, very low oxygen levels found in my baby. Will he have cp?

Hard to say: The fetus has low oxygen levels compared to the rest of us for the duration of the pregnancy. Any lab value must be put in context with what is happening.How low, for how long and with what other abnormalities provides a better predictive value. For some premi's, they try to keep it in a lower zone to help prevent eye damage caused by too high oxygen levels while the eyes are developing. ...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

Low hemoglobin in toddler ?

Low hemoglobin in toddler
?

Most common low iron: The most common cause of anemia in a toddler is iron deficiency. Usually this occurs in a toddler that drinks alot of milk, and not much else (not eating foods rich in iron). This is easily diagnosed and reversible with iron supplementation. If this is not the cause, then either blood loss (small amount in stool over time?) or hemoglobinopathy possible (and other things) - see a peds hematologist. ...Read more

Why would patients with COPD be given low flow concentration (1-2l/min) supplemental oxygen?

Low blood oxygen: At the advanced stages of copd, the lungs do not perform their function well, oxygen has a harder time crossing into the blood stream. At this point, the body is not getting enough energy, the blood oxygen level is low. Raising the amount of inhaled oxygen offsets the problem, and prolongs life. Oxygen is used at the lowest amount that would achieve the goal. ...Read more

At what level is low blood oxygen harmful for children with copd?

At what level is low blood oxygen harmful for children with copd?

See below: Children usually don't have copd, this is a disease of the adult. Children may have congenital lung diseases but the physiology of those is not the same as copd. Blood oxygen levels less than 90% are generally not desired. Hope this helps. ...Read more
