Abstract
Introduction: Colors and their effect on the human mind and body have been investigated in various ways, and patients admitted to the intensive care unit experience a lot of stress due to environmental factors and special treatment conditions. This study was conducted to compare the effect of blue and green light with normal light on the vital signs and anxiety levels of patients admitted to the Coronary care unit (CCU).
Materials and Methods: This clinical trial was conducted on 75 patients admitted to the CCU department of Imam Khomeini Hospital in Esfarayen North Khorasan in 2021-2022. Patients were randomly assigned to three groups of blue, green, and white light, and vital signs were measured every half hour, and patients' anxiety was measured twice (at the beginning and end of the study) using the Spielberger questionnaire.
Results: The variables of pulse, breathing rate, blood pressure, temperature, and anxiety levels appeared no significant differences between the subjects of the intervention groups and the control group (p>0.05). In the intervention group with blue light, blood oxygen saturation levels on the first and second day and on the second and third showed a significant difference (p<0.05).
Conclusion: There was no difference between the effect of blue, green light, and white light on the level of anxiety, breathing, blood pressure, temperature, and pulse rate; But blue light had an effect on blood oxygen saturation level. It is suggested to study more in this field.
