Abstract
Background and objective: Oxyhaemoglobin saturation of arterial blood is commonly measured using a finger sensor attached to a pulse oximeter (SpO 2). We sought to compare SpO2 measured using finger and forehead sensors with oxyhaemoglobin saturation in arterialized capillary samples (ACS) in people with chronic obstructive pulmonary disease (COPD) during exercise. Methods: During aerobic exercise, SpO2 was measured continuously by two pulse oximeters: one connected to a finger sensor and to a forehead sensor. Before and after the task, ACS were collected to provide a minimally invasive reference measure of oxyhaemoglobin saturation. Patients with COPD were eligible for inclusion if they desaturated when walking by >4% from resting levels to
