PURPOSE: Entrainment of the breathing rhythm to that of the rhythm of limb movement during exercise has been shown to reduce oxygen consumption. Pursed-lip breathing (PLB) has also preventable effects against hypoxemia. This study examined the effect of entrained PLB on walking induced hypoxemia in patients with obstructive lung diseases.

METHODS: Ninety patients (77 men, 13 women; mean age, 75.0 ± 8.3 (SD) years) with obstructive lung disease (mean %FEV1; 57.4 ± 22.5% predicted, COPD; 73, BA; 6, Bronchiectasis; 4, CPFE; 7) who were referred to outpatient pulmonary rehabilitation clinic were studied. All patients were in a clinically stable condition. At first, PLB alone, and then, entrained PLB with walking, were instructed by a physiotherapist to the patients. Before and after this instruction, the walking was tested at patient’s own rhythm and speed. During the walking test, SpO2 and dyspnea (Borg CR10) were monitored. Patients were advised to stop walking when they had SpO2 less than 88% or severe dyspnea (scale 5 in Borg CR10).

RESULTS: Before the instruction, SpO2 decreased from 95.4 ± 1.5% to 91.0 ± 2.9% (p<0.0001) and CR10 increased from 0.4 ± 0.6 to 2.0 ± 1.7 (p<0.0001) after the walk. After the instruction of PLB alone, the change in SpO2 and dyspnea improved from -4.4 ± 2.1% to -3.1 ± 2.5% (p<0.0001) and 1.9 ± 1.7 to 1.8 ± 1.5. After the instruction of the entrained PLB, further improvements were observed: the changes in SpO2 and dyspnea were 1.9 ± 1.7 % and 1.2 ± 1.3 (p<0.0001).

CONCLUSIONS: Entrained PLB possibly prevented walking induced desaturation and dyspnea.

CLINICAL IMPLICATIONS: Entrained PLB with walking might be useful as a rehabilitation program to improve patients with walking induced hypoxemia and/or dyspnea.
