Patients’ perspectives on the use of pulse oximetry at home

Although pulse oximeter possession is common among patients with respiratory diseases, their experiences with these devices are unexplored. Aim: To examine knowledge, understanding and usage patterns of pulse oximeters and their impact on self-management. Methods: Thirty participants with chronic respiratory diseases (mean age 71 years; 16 females; 60% COPD; 83% on home oxygen) were recruited and completed a structured survey. Results: Pulse oximeters were purchased online (46.7%) or at a pharmacy (40%). Use was self-initiated (56.7%) or recommended by health professionals (16.7%) or family (13.4%). Sixty percent of participants used the device daily. Ninety percent of participants were confident in interpreting the oximeter reading (SpO2) although 20% felt they needed further education. Participants learnt how to interpret a pulse oximeter reading from medical professionals, pulmonary rehabilitation, the internet and through inpatient experiences. Ninety percent of participants often adjusted their activity levels or management, including through titrating oxygen flow rates, according to their measured SpO2. Low readings led participants to limit activities, to increase medications (including opiates), to increase oxygen flow rates and to perform deep breathing exercises. Most participants reported that home use of a pulse oximeter was helpful in judging their physical limitations and provided reassurance and confidence in their disease management. Conclusion: Participants in this study appeared confident in their home use of pulse oximeters. Health professionals should identify patients who use pulse oximeters at home, and ensure that they are able to interpret the readings and, if appropriate, adjust management safely.
