CONFUSED BY LATEST LUNG FUNCTION RESULTS
My husband has recently seen his pulmonologist and given his latest test results. I am somewhat confused by them. The previous three tests all showed a decline in both FEV1 and FVC but this one has increased from 3.49 to 3.84 and 3.91 to 4.23 respectively with FEV1/FVC ratio at 91% but his DLCO has stayed at 46% and his KCO is 59% (we have never been given a KCO reading before). He does appear to be more out of breath recently too. His doctor is concerned about a nodule on his latest CT scan and has prescribed anti-biotics and wants a repeat CT scan is a couple of weeks. The other confusing thing is his Heart rate on the pulse oximeter. His oxygen is 98% on both hands but his heart rate is 68 on his left hand and approximately 110 on his right hand.
Can anyone tell us why his results would improve even though he appears to be declining.
