Effects of Thyme Oil on Respiratory Systems, Hemodynamic Parameters and Vital Signs in COPD Patients

The present study aimed to determine the effects of aromatherapy through thyme oil inhalation on respiratory symptoms, hemodynamic parameters and vital signs in COPD patients. The pre-test post-test randomized controlled experimental study was conducted with inpatients COPD (intervention group = 60, control group = 60). Data were collected using the "Patient Information Form", "COPD Symptoms Form", and "Hemodynamic Parameters and Vital Signs Monitoring Form" as well as a saturation device. Following the pre-test, patients in the intervention group inhaled thyme oil 3 times a day for 5 days but the control group did not receive anything. COPD symptoms and hemodynamic parameters were measured on the fifth day as the post-test. Vital signs were measured and recorded 3 times every day over 5 days. It was found that thyme oil application through inhalation significantly reduced all COPD symptoms (dyspnea, cough, secretion, etc.) in the intervention group compared to the control group. pH and O 2 levels were higher while CO 2 levels were lower in the intervention group, and as of the third day, saturation levels were higher whereas respiratory rates were lower. In this regard, thyme oil is recommended as a non-pharmacological treatment method for COPD patients.
