PURPOSE: Determine the effect of lightweight (<5lbs) pulse wave portable oxygen concentrator (POC) on improvements in functional capability, dyspnea, quality of life; prevention of emergency room encounters and hospital admissions.

METHODS: Protocol for study reviewed/approved by IRB; patients pre-screened for inclusion criteria (COPD: FEV1≤70%; FEV1/FVC≤70%; oxygen 24h/d). N=30 selected for study between October - April. Patients consented and completed Baseline Dyspnea Index (BDI), Chronic Respiratory Disease Questionnaire (CRQ); Six Minute Walk Test (6MWT) to identify baseline POC setting for SpO2≥92% at rest and activity at MD office and home by respiratory therapist (RT). Patients completed Transitional Dyspnea Index (TDI), CRQ, 6MWT with oximetry to acheive SpO2≥92% at rest and activity on POC at 2-week intervals in MD office and alternate 2-weeks at home by RT. Patients encouraged to use POC for ≥15 h/d while awake; instructed to use continuous flow device when sleep.

RESULTS: Preliminary results: n=18 (12 males, 6 females with a mean ± SD age of 76 years; mean ± SD years with COPD 7.1.; mean ± SD years with LTOT 4.2.); Mean ± SD SpO2 at rest 95% at mean ± SD POC setting 2; Mean ± SD SpO2 w/activity 93% at mean ± SD POC setting 2; after baseline visit: mean ± SD 6MWT for all patients on outcome measures improved significantly (P < 0.01) and correlated with CRQ, TDI (P<0.05); paired t-tests indicated that on POC that CRQ functional activity domain and TDI measures improved in both groups. Of preliminary results n-1 admitted for respiratory related illness in winter months, but completed study post discharge and showed improvement in functional ability; n-3 disenrolled due to preference with their oxygen device but showed initial improvement in outcomes measures.

CONCLUSIONS: Preliminary results for all patients showed improvement in quality of life and dyspnea; overall activity levels improved due to increased adherence to oxygen therapy during the three (3) month observational period. All patients showed improvement in the dyspnea scores for all components of the CRQ and TDI. Home visits by the RT helped to reinforce patient’s knowledge, education of COPD and adherence to therapy.

CLINICAL IMPLICATIONS: A lightweight (< 5lbs) pulse wave delivery portable oxygen concentrator (POC) used for patients with moderate to severe COPD can help improve the patient’s functional ability, quality of life, prevent emergency room encounters and hospital admissions by increasing compliance with oxygen therapy.
