Air Embolism (Definition)

Blood vessels are made to carry blood - liquid. A small amount of air in a vessel is not usually a big deal as it will be absorbed into the blood. Larger volumes of air (10 mL or larger) can be significant to block blood flow in that vessel. That is bad in the brain (stroke) and really bad in the heart because ...Read more

Clarify:cardiac output too high at rest? Echo:stroke volume 100ml by 70 bpm, that means cardiac out:7l/min; cardiac index would be 3, 57l/min*m2.Txs

Clarify:cardiac output too high at rest? Echo:stroke volume 100ml by 70 bpm, that means cardiac out:7l/min; cardiac index would be 3, 57l/min*m2.Txs

High Cardiac Output: Cardiac output is calculated by multiplying stroke volume by heart rate. Since the amount of blood pumped by the heart is dependent on body surface area ie. A larger person needs more blood supply. If it is more than 6l/min in an average person, at rest , and associated with symptoms, the cause must be looked into. ...Read more

Respiratory function: You've listed a lot of tests that were normal and that is good, but if your primary symptom is "lack of air", it may be worthwhile to perform some simple pulmonary function tests which evaluate your ability to fill your lungs and exhale. Has your doctor evaluated you for asthma or allergies as well? ...Read more

Can blood pressure affect pulse oximeter readings?

Can blood pressure affect pulse oximeter readings?

Not usually..: The only effect would be if the blood pressure is extremely low causing poor peripheral blood flow. In this instance, the pulse ox may be inaccurate. This could occur in shock situations. As long as the blood flow remains normal, the blood pressure will not affect pulse ox. ...Read more

Normal ECG normal oxygen normal chest X-ray normal BP pulmonary embolism??

Normal ECG normal oxygen normal chest X-ray normal BP pulmonary embolism??

Not usually: all the things you report are reassuring but there is no clinical context, such as chest pain, shortness of breath, blood gas. The best test for PE is a CT scan of the chest with contrast , however this may miss small emboli and may be negative after 24-48 hours . IT is hard to be certain from the little data provided . Why did you or your doctor think you might have a PE? ...Read more

Oxygen saturation 95% pulse 65 should I be worried?

Are you sick?: Any measured finding has to be correlated with your condition. If you feel fine, then these values are okay. Do you smoke? If you feel bad: have shortness of breath, cough, fever, chest pain, etc. and if you repeat them and the numbers are the same, then you should get seen quickly. Either value can be normal, or indicate a problem, depending on what is going on at the time you measure them. ...Read more
