Air Embolism Pulse Oximetry Low
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
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 moreSee 1 more doctor answer
