Adult participants of both sexes with COPD and PID, prolonged oxygen use, will be evaluated after being informed about the study, agreeing and signing the informed consent form. Participants will be randomized to a control group and a group monitored for 90 days. The monitored group will receive a wearable device to monitor vital signs of heart rate and oxygen saturation and the control group will receive a pulse oximeter. Both groups will be monitored through the cell phone application.
