Summary

This study is a pre-test post-test randomized controlled trial aimed at examining the effects of thyme oil inhalation on asthma control and respiratory parameters in patients with asthma. It will be conducted with 150 patients (intervention group = 50, placebo group = 50, control group = 50) in the pulmonary ward of a Training and Research Hospital in eastern Turkey. Patients will use either thyme oil-infused or placebo inhaler sticks, inhaling for eight breaths, three times a day for four days. The placebo group will receive an empty inhaler stick, while no intervention will be applied to the control group. Data will be collected from November 2024 to February 2025. The effects of thyme oil will be measured using the Asthma Control Test, Asthma Symptom and Respiratory Parameters Form, FEV1 (Forced Expiratory Volume in 1 second), and FEV1/FVC (Forced Expiratory Volume in 1 second to Forced Vital Capacity ratio) (Modified Tiffeneau-Pinelli index) values.

Hypothesis: It is hypothesized that thyme oil inhalation will significantly improve respiratory function parameters and asthma control levels in patients with asthma.

Conditions

Interventions

OTHER

Experimental

Patients will inhale thyme oil via inhaler sticks with instructions on proper usage, supervised by the researcher. Each patient will complete the Patient Introduction Form, Asthma Control Test, and pre-test sections of the Asthma Symptom and Respiratory Parameters Form. Measurements of FEV1 and FEV1/FVC will be recorded. On the fourth day of hospitalization, post-test data will be collected.

OTHER

Placebo

Patients will receive an empty inhaler stick with usage instructions, completing the same pre- and post-test procedures as the intervention group.

OTHER

Control (Standard treatment)

Patients will complete pre- and post-test forms without any intervention.
