June 17, 2009 Pulmonary Fuction test, slow COPD progression

Posted Jun 17 2009 6:07pm

An Okay day for me, how about you?

Keep moving about - doing what you have to do, and some things you may not WANT to do, but you do it anyway. That is a good attitude, keep trying. . My doctor was amazed that I continue to improve in some areas, on paper that is, of the pulmonary function test.. I think they expect me to burn out on my exercise (and so do I sometimes). As I explained yesterday, it isn' t REAL improvement, just better functioning by reason of finding an excellent combo of inhalers for me that shows up in the test. Hey, that is fine by me, I ' feel' better and can do more while on these inhalers. Each year my FEV 1 "appears" to improve, as do other numbers. The FEV1/FVC gives a ratio that shows the amount of obstruction, and that remains pretty constantly between 51-54%. Thus the doctor called it mild to moderate obstruction, and he says my 86% FEV1 [up from in the low 70% area, is an "anomaly". NOT the whole story, that my CT scan showing all the dead air pockets scattered about and mostly thick at the lower lung area gives the real picture���that and my diffusion in the 53-63% area here at 5500 ft altitude gives me extra challenges getting sufficient oxygen to run my body.

Now that I can fast walk 15-20 minute miles I require 10-15 liters. For very slow, a small amount , of only 2 L around home or 3 for simple shopping holds my sats, because I have TTO

Today I didn' t have time to look up some reading because I had to be the driver���my husband had his second cataract operation. Lots of prep, but the actual procedure only takes 10-12 minutes, amazing. From the hour + drive, I got pretty tired along with having to rise and shine extra early.

Common Terminology of Spirometry Tests Critical in Diagnosing COPD

VC-Vital Capacity - The amount of air that can be forcibly exhaled from your lungs after a full inhalation.

FVC-Forced Vital Capacity - The amount of air which can be forcibly exhaled from the lungs after taking the deepest breath possible.

FEV1-Forced Expiratory Volume in One Second - The amount of air which can be forcibly exhaled from the lungs in the first second of a forced exhalation.

FEV1/FVC-FEV1-Percent (FEV1%) - The ratio of FEV1 to FVC and tells the clinician what percentage of the total amount of air is exhaled from the lungs during the first second of forced exhalation.

PEFR PeakExpiratory Flow Rate- Measures if treatment is effective in improving airway diseases such as COPD.

FEF-Forced Expiratory Flow - A measure of how much air can be exhaled from the lungs. It is an indicator of large airway obstruction.

MVV-Maximal Voluntary Ventilation - A value determined by having the patient inhale and exhale as rapidly and fully as possible in 12 seconds. The results reflect the status of the muscles used for breathing, how stiff the lungs are and if there is any resistance in the airways when breathing. This test tells surgeons how strong a patient' s lungs are prior to surgery. If patients demonstrate poor performance on this test, it suggests to the doctor that respiratory complications may occur after surgery.
