Pulmonary rehabilitation is an exercise and education program developed to counteract the systemic effects of chronic respiratory disease. For people with chronic lung disease, it reduces dyspnea, lowers the risk of hospital readmission after acute exacerbation, and improves exercise capacity and quality of life.

Despite widespread recommendations that people with chronic lung disease attend these programs, less than 1% of them do. This is partly because of issues related to location and transportation. One way around this is to deliver pulmonary rehabilitation to the patient in their own home via internet-based video link.

This has also been shown to be very effective. However, one things that is typically done in face-to-face, hospital-based pulmonary rehabilitation is monitoring of the patient's heart rate and oxygen levels with a non-invasive probe that attaches over the patient's finger.
