In a patient with air embolism all of the following are true except:
|A||Transesophageal echo (TEE) is the most sensitive investigation|
|B||It should be measured over a continuous cycle|
|C||It can calculate the volume of air|
|D||It interferes with Doppler reading when they are used together|
It interferes with Doppler reading when they are used together
a. Venous air embolism is most commonly seen in sitting position.
b. TEE is the most sensitive test to detect venous air embolism followed by Doppler (10 times less sensitive than TEE) and then end tidal carbon dioxide.
c. It should be measured over continuous cycle and it can measure as low as 0.02 ml of air.
d. It does not interfere with Doppler.
