The Effects of Aromatherapy With Thyme Oil on Disease Symptoms, Vital Findings, and Hemodynamic Parameters in COVID-19 Patients: A Randomized Controlled Trial.

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.
