WebThe helium dilution technique is the way of measuring the functional residual capacity of the lungs (the volume left in the lungs after normal expiration).. This technique is a closed-circuit system where a spirometer is filled with a mixture of Helium and Oxygen. The amount of He in the spirometer is known at the beginning of the test ( Concentration x Volume = … Webhelium dilution test should be continued until helium reading changes by less than 0.02% in 30 sec or until 10 minutes have elapsed helium dilution method multiple measurements of FRC should agree within 10% what should be reported on helium dilution method average of multiple acceptable measurements
Webstatement on general considerations for lung function testing in this series of documents [19].

VA: 3.64. 88%. When compared to the FVC and the VA (from the DLCO test) the lung volumes are significantly lower. In particular the FRC and RV are markedly reduced. This is somewhat unusual for helium dilution lung volume since most errors usually cause FRC, RV and TLC to be over-estimated instead of being under-estimated.
