For those of you familiar with idiopathic pulmonary fibrosis (IPF), or any interstitial lung disease (ILD), actually, you will likely know what a pulmonary function test is. If you are a patient with any type of ILD, chances are you have had a pulmonary function test, or many, as doctors and specialists monitor the progression of your disease.
I used to dread having these tests done, not because they are invasive in terms of being poked or prodded with needles, but because I often saw or was told that my lung function was declining. Various measurements are taken during a pulmonary function test, which can be read independently of each other and are read collectively to summarize how your lungs are functioning. Done frequently, it used to scare me as I was told repeatedly with each pulmonary function test that my lungs seemed to be getting worse.
Lately, however, with an adjustment to my medications, as well as an intense pulmonary rehabilitation regimen, I have seen my lung function stabilize over my last few pulmonary function tests. When people ask me how my appointments go, and I respond that things are stable, they’re often surprised when I appear happy to report stable rather than improved.
Here’s the thing: No two ILDs are the same, and even patients with the same disease find it can manifest itself and progress very differently from patient to patient. Because of this, protocols and the way a disease is treated and monitored for each person vary. That’s the reason some doctors and specialists can stabilize the progression of a disease in one patient but not in another.
I have witnessed people with IPF, some of whom I would now consider close friends, quickly deteriorate because their disease progressed rapidly. I have seen others whose lung function and disease remain stable for several years before anything changes for them.
The truth is no one really knows why this difference exists. So I truly am happy when I can report that things are stable with my lungs, even though there may not be an improvement. In fact, I would be happy if my lungs remained stable for another several years.
I often say to my colleagues that if my lungs would just stabilize and I could wean myself off oxygen when doing stationary things, I’d be happy. I would be happy to be able to get up from my desk and walk to the bathroom without being tethered to something by a nasal cannula. I know how unlikely it is that I will be able to participate in active exercises for my lungs, or anything that is high-impact and is a good workout, and I am OK with this. All I want is to be able to have short periods off my oxygen and not feel like I am drowning or gasping for air.
For this to happen, I need to hear that my lungs are stable and, therefore, not declining, so I can try to push them a little bit as part of my weaning plan. So, yes, I am very happy when the results of my pulmonary function tests indicate stable. In a perfect world, they would show improvement and would continue on that trend of getting better and better. But we don’t live in a perfect world. If we did, IPF and many other ILDs would not exist.
To other IPF patients out there: What do you hope for when you receive the results of your pulmonary function tests? Although I write about being happy when things are stable, it does feel a little strange not to be actively hoping for improvements. There are two reasons for this. First, I don’t want to be unrealistic because improvements in patients with IPF are rare. The fibrosis, or scarring, is permanent and is not reversible. And second, because improvement can push us farther away from receiving a lung transplant.
As you know, lung transplant is the only cure for IPF, and it is a strange balance of essentially being sick enough to warrant being placed on the list and receiving organs, and being strong enough to recover physically from such intense surgery.
When I think about what I want from my pulmonary function tests, I think the biggest hope I have is that things are stable enough for me to just continue living my life the best I can by doing the things I love.
