Lung Volume Reduction Program

Improvement in Lung Function and Exertional Capacity

Patients who underwent LVR surgery at Cleveland Clinic between 2004 and 2021 showed improvement in lung function, as measured by forced exhaled volume in 1 second, and exertional capacity, as measured by 6-minute walk test distance.

Improvement in Lung Function

2004 – 2021

FEV₁ = forced exhaled volume in 1 second

Improvement in Exertional Capacity

2004 – 2021

Probability of Survival After LVR Surgery

2004 – 2021

When compared with the NETT cohort,¹ the Cleveland Clinic cohort achieved similar probability of survival at 1, 3, and 5 years postoperatively.

LVR = lung volume reduction

ᵃNETT cohort data for upper lobe predominant, low exercise capacity patients
