Effect of Manual Chest Wall Vibration on Respiratory Function and Chest Tube Duration After Thoracic Surgery

Condition(s) studied

Investigational drug(s) / intervention(s)

Chest Wall Oscillation: Manual chest wall vibration is applied with the patient in a semi-Fowler's position during the expiratory phase of breathing. The practitioner places both hands flat on the chest wall and delivers gentle, rhythmic vibrations, starting from the lower lobes and progressing toward the upper lobes. Patients are instructed to inhale slowly through the nose and exhale using a pursed-lip breathing technique with a 1:2 inspiration-expiration ratio. The procedure is performed for approximately 5 minutes, corresponding to about 10 respiratory cycles, and is typically applied during the patient's rest period following routine care.

Conventional Control: Control group patients were informed about the study and provided written consent. They received only routine nursing care, with no additional interventions applied. Baseline measurements were taken at 0 minutes, including dyspnea (MBS), pain (VNRS), vital signs, and arterial blood gas values. Following routine care, the same parameters were reassessed at 3, 5, and 10 minutes and recorded. No manual chest wall vibration was performed; only standard clinical monitoring was maintained. The same assessment protocol was repeated in the evening session.

Study summary

This study was conducted to determine the effects of a manual vibration technique applied to the chest wall on the duration of chest tube placement, secretion clearance, and hemodynamic parameters in patients with chest tubes.

Eligibility

Primary outcome measure(s)

• Patient Follow-Up Form — 1 day
  Changes in respiratory and hemodynamic parameters (including respiratory rate, peripheral oxygen saturation, heart rate, blood pressure), dyspnea severity (Modified Borg Scale), and pain intensity (Visual Numeric Rating Scale) measured before the intervention and at 0, 1, 5, 10, and 15 minutes after the intervention.
