Effectiveness of Audio-Visual Education on Physiological parameters among patients undergoing Coronary Angiography

Audio-visual education have a positive impact on stabilize the physiological parameters such as blood pressure and heart rate. The main aim of the study was to identify the effectiveness of audio-visual education on physiological parameters among patients undergoing coronary angiography. Quasi experimental posttest only control group design was adopted in the study. By using Non probability purposive sampling technique 60 study participants were selected and 30 were assigned to the experimental and control group respectively. The demographic variables, health history was collected from the patients undergoing coronary angiography. Audio- Visual Education was provided to the patients in the experimental group for 15 minutes. Routine nursing care was provided to patients in the control group. The vital signs 30 minutes before and after the intervention in both groups were measured. The experimental group showed a statistically significant decrease in the heart rate and blood pressure after the Audio-visual education compared to the control group (P < 0.05). Hence, it was concluded that using Audio-visual education before coronary angiography can effectively maximize the patients outcome. The results of this study confirms the usefulness of prior to an invasive coronary angiography procedure.
