It's time to report my bi-annual pulmonary function test results. Drum roll... I am continuing to improve, although my pulmonologist told me that I will plateau at some point. In addition to Tagrisso working its magic, I have to think that strength training and biking (including 2 short interval training [SIT] workouts/week) are a big contributing factor.
The percentage below indicates my result compared to the expected result for a woman my age.
FEV1 (forced expiratory volume) measures the air you exhale in 1 second.
May 2024: 98% (34% improvement since 10/22)
Nov. 2023: 95%
May 2023: 91%
Oct. 2022: 73%
TLC (total lung capacity) is the total volume of air in the lungs after inhaling as much as possible.
May 2024: 102% !! (48% improvement since 6/22)
Nov. 2023: 95%
May 2023: 83%
Oct. 2022: 72%
Jun. 2022: 69%
DLCO (diffusing capacity of lung for carbon monoxide, aka diffusion) is the extent to which oxygen passes from the lungs into the blood. It indicates the extent of lung damage. I have improved 110% since June 2022, when I was first diagnosed with lung cancer. Although 86% is within normal range, I believe this figure explains why I still need supplemental O2 when doing more strenuous exercises, like heavier lifts or those awful Bulgarian/rear-foot elevated split squats.
May 2024: 86%
Nov. 2023: 82%
May 2023: 68%
Oct. 2022: 49%
Jun. 2022: 41%
FYI, for comparison, Normal DLCO = >75% of predicted; Mild = 60% to 75%; Moderate = 40% to 60%; and Severe = <40%. So I started out borderline severe, graduated to moderate, then mild, and now normal since Nov. 2023.
Together, these results explain why I can now walk uphill from downtown and not feel out of breath.
I've now graduated to lung testing every 8-9 months. For once, I'm an outlier because of how much I've improved rather than all the things that have gone wrong.
This is such great news Esther. I can't help but think that your very hard physical work to recover plays a huge role in those great numbers. You have much to be proud of. You're a warrior!!
ReplyDeleteThank you, anonymous friend. Fight on.
DeleteWoohoo Ester ! You have taken huge leaps and conquered !
ReplyDeleteThank you! Still working on the conquering part...
DeleteAwesome news, Esther! You are rocking this! And thanks for explaining all the acronyms — I need this all the time with medical data!
ReplyDeleteYes, I have them written down because I can never remember what they mean.
DeleteHooray! So glad to hear this!
ReplyDeleteThanks, Kristen!
DeleteYou're everyone's role model and your recovery is inspiring. Probably helps that you've been pretty much a lifelong fitness fanatic, and that your family, for that matter, similarly spends fewer than 10 hours/day in front of a television
ReplyDeleteThank you, David. You're right about lifelong fitness...but you underestimate how much TV we watch. :) Leland and I watch 1-1.5 hours together every evening and Lily often joins us when not at vball. Plus Leland often watches stuff on his own. He often quotes The Simpsons: "TV gives so much and asks so little."
DeleteGreat news, Esther! Very encouraging and motivational! My mother has lung problem and she is doing the physical training too. I know the oxygen level, it's good to learn other terms that you described and that the physical training is really helpful! Bo
ReplyDeleteAll fantastic news Esther! God is good. You will continue to be healed! Keep moving forward & looking to the heavens for your help. Your help comes from the Lord. 🙏🏽
ReplyDeleteThis report makes my heart sing! You've certainly done your part to make this report happen. You are a good role model for me, should I face a similar situation. Lois C
ReplyDeleteWOW!! Thanking & praising God for this tremendous improvement, Esther!! Those stats show your dramatic progress. Celebrating with you!!
ReplyDeleteCongratulations on being an 'outlier' in the other direction!!
