The purpose of this evidence-based nursing practice paper is to discuss the effectiveness of deep-breathing exercises in the care of a patient who is recently postoperative a coronary artery bypass graft surgery (CABG). It will also critique two professional research studies on this topic, and will answer three essential questions about each study. What are the results of the study? Are the results of the study valid? How are the findings clinically relevant to this patient? The patient, who will be referred to as Mr. Doe throughout this paper, is a 58 year old male with coronary artery disease. His medical history includes angina, shortness of breath, diabetes type II, as well as hypercholesterolemia. He was scheduled for a CABG surgery, and it was performed on February 4 of this year (Mr. Doe, personal communication). Two days postoperative, Mr. Doe had regular complaints of pain and nausea, for which he was medicated for by a patient-controlled analgesia (PCA) pump and with intravenous medication. He had diminished breath sounds in his right and left upper lobes, and his O2 saturations were steady at 94%. He was reluctant to ambulate in the early morning, stating that the nausea was too severe, and that the medications “made him too dizzy,” (Mr. Doe, personal communication). It was also difficult to get Mr. Doe to perform deep-breathing exercises every hour because of the nausea, but he did perform them when prompted to by the nurse and being reminded how important these exercises are in preventing complications. Deep breathing exercises are very important after any surgery. Current research states that “postoperative hypoventilation can be a problem after abdominal or thoracic surgery if pain prevents the patient from ... ... middle of paper ... ...patients.
