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

My blood oxygen saturation is 96% but can there be chances that my blood is not circulation properly to my skin?

My blood oxygen saturation is 96% but can there be chances that my blood is not circulation properly to my skin?

Yes.: At your age chances of lack of circulation is unlikely unless there are preexisting conditions like diabetes or rheumatologic problems like sle, etc.. Smoking can also cause it as do some drugs that cause vasoconstriction or closing off of blood vessels. ...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

How serious is a 81% oxygen saturation reading on room air combined with a po2 of 46 mmhg? Could it be an indication that death is imminent in an elderly person?

How serious is a 81% oxygen saturation reading on room air combined with a po2 of 46 mmhg?  Could it be an indication that death is imminent in an elderly person?

Yes: An oxygen saturation, the % of o2 in the blood generally is >95 in a healthy person, other illnesses may cause that to change. End stage disease(of any kind) can lead to low o2 levels as a natural part of the dying process. As long as the person is not experiencing any discomfort and the goal is comfort only- checking o2 levels may not be indicated and only more distress to the caregivers. ...Read more

Why when i get difficulties breathing or sob, yet my oxygen saturation is 99-98% . How and what could that be. What is the symptom of low oxg saturat

Dyspnea: Shortness of breath is largely unrelated to oxygen levels, except when very low. Work of breathing causes dyspnea (shortness of breath) and can occur with normal oxygen levels. When oxygen levels become very low dyspnea can occur. ...Read more

How much does a low oxygen saturation level affect judgment?

Oxygen: A low oxygen saturation definitely affects judgment. Your brain is one of the organs that is heavily dependent on proper oxygenation. If you decrease the oxygen saturation, judgment may be impaired. ...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

How much can a low venous oxygen saturation affect judgement?

How much can a low venous oxygen saturation affect judgement?

Depends: Low oxygen levels can affect someone's judgment and arousal. But, this is variable between people. I have met plenty of people with very low oxygen levels and can act and feel fine. So, there is no general rule about that... ...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

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

Can anxiety attacks cause oxygen saturation to drop?

Can anxiety attacks cause oxygen saturation to drop?

Potentially: If you have COPD or severe asthma and your ability to get enough air is already compromised, then yes, panic attacks can cause oxygen saturation to drop by hyperventilation and shallow breathing, but generally not meaningfully if otherwise in good health. ...Read more

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

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

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

What does it mean if I have high oxygen saturation but a low heart rate?

What does it mean if I have high oxygen saturation but a low heart rate?

See below: It means that the hemoglobin in your blood is receiving enough oxygen from your lungs to be fully loaded with oxygen molecules. Additionally, your heart, for whatever reason, is beating slowly. Often, slow heart rate is a sign of health, particularly in your age group (37). ...Read more
