The Effect of Slow Breathing Exercise Applied to Patients on Pulse, Blood Pressure and Quality of Life

Slow breathing exercise training will be given by the researcher in a single one-hour session in the meeting room of the unit 24 hours after the PCI and/or the next day. After a 20-minute silent rest in the training, patients will be asked to breathe slowly through the nostrils for 4 seconds and slowly exhale through the mouth for 6 seconds to reach 6-8 breaths/min. The patient will rest for 5 seconds after every 6 slow breaths. During the training period, a stopwatch will be used by observing the patient's chest and abdominal movements in order to determine whether the patients have reached the required respiratory rate.
