Comparison of forehead and finger oximetry sensors during the six minute walk test.

ABSTRACT:

Background

Measurement of oxygen saturation (S_pO₂) during the 6 minute walk test (6MWT) could be impacted by the measurement site.

Aims

To compare S_pO₂ and heart rate (HR) between forehead and finger sensors during the 6MWT. Sensor readings were also to be compared for signal quality and with capillary blood gas (CBG) pre and post 6MWT.

Method

80 subjects with pulmonary vascular disease (PVD) and/or interstitial lung disease (ILD) performed the 6MWT. Pulse oximetry was recorded at 30 s intervals. CBG was taken pre and post 6MWT to determine capillary oxygen saturation (S_CO₂).

Results

The forehead sensor recorded higher values for S_pO₂ (p < 0.001) and HR (p < 0.
