Real-time telehealth for COPD self-management using Skype™.

The utility of real-time interactive voice and video telehealth for teaching pursed-lips breathing (PLB) in chronic obstructive pulmonary disease (COPD) is unknown. This was a pilot study to determine its feasibility and efficacy on the key variables of social support and dyspnea. A randomized control study design with repeated measures (baseline, 4 and 12 weeks) was used.

Efficacy of pursed-lips breathing: a breathing pattern retraining strategy for dyspnea reduction.

Purpose: Breathing pattern retraining is frequently used for exertional dyspnea relief in adults with moderate to severe chronic obstructive pulmonary disease. However, there is contradictory evidence to support its use. The study objective was to compare 2 programs of prolonging expiratory time (pursed-lips breathing and expiratory muscle training) on dyspnea and functional performance.

Usefulness of the human activity profile, a functional performance measure, in people with chronic obstructive pulmonary disease.

Purpose: To further evaluate the usefulness of the Human Activity Profile (HAP) as a functional performance measure for those with chronic obstructive pulmonary disease (COPD).

Methods: Phase 1. The sample consisted of 53 outpatients (51 male) with stable COPD (forced expiratory volume in 1 second% predicted (FEV1% pred) = 38 +/- 14 (mean +/- standard deviation) at a university-affiliated veterans affairs medical center.

Comparison of breathing patterns during exercise in patients with obstructive and restrictive ventilatory abnormalities.

Patients with obstructive and restrictive ventilatory abnormalities suffer from exercise intolerance and dyspnea. Breathing pattern components (volume, flow, and timing) during incremental exercise may provide further insight in the role played by dynamic hyperinflation in the genesis of dyspnea. This study analyzed the breathing patterns of patients with obstructive and restrictive ventilatory abnormalities during incremental exercise.

Smoking cessation care received by veterans with chronic obstructive pulmonary disease.

Smoking is the main cause of chronic obstructive pulmonary disease (COPD), and smoking cessation is the only effective intervention to slow its progression. We examined whether smokers with COPD received more cessation services than smokers without COPD. Current smokers from 18 Veterans Health Administration primary care clinics completed baseline and 12 month follow-up surveys (baseline n = 1,941; 12 month n = 1,080), composed of validated questions on smoking habits, history, and attitudes; health/functional status; and sociodemographics.
