Using a vibroacoustic lung device for respiratory failure in older patients with hip fracture

Official title: The Course of Acute Respiratory Failure in Geriatric Patients With Hip Fracture Using Different Modes of a Vibroacoustic Device for the Lungs

Run by Astana Medical University · NCT07517497 · Data updated 2026-11-12

This will test whether using the vibroacoustic lung device in 'Pneumonia' versus 'Prevention' mode helps older patients with hip fractures who have acute respiratory failure.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are older adults with hip fracture who have acute respiratory failure and an Injury Severity Score of 8 or lower and who do not have contraindications to the device.

Probably not a fit

Patients with listed contraindications (for example unstable rib or spinal fractures, severe coagulopathy, recent stroke, shock, terminal condition, or Injury Severity Score >8) are unlikely to benefit or be eligible.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

Patients with hip fracture and acute respiratory failure will receive vibroacoustic pulmonary therapy delivered by a trained clinician, who will also collect blood samples. Participants are assigned to receive the device in one of two modes ('Pneumonia' or 'Prevention') with sessions 4–6 times per day, five minutes each, for five days. The device emitters are applied to the affected lung areas and the portable design allows treatment of ventilated or immobile patients without their active participation. A similar treatment algorithm is used in both groups and standard medical care is continued per local protocol.

Why it matters

Potential benefit: If successful, this approach could improve airway clearance and reduce respiratory complications in elderly hip fracture patients with acute respiratory failure.

How similar studies have gone: Chest vibration and oscillation therapies have some evidence for aiding secretion clearance, but use of this specific vibroacoustic device and its modes in geriatric hip fracture patients is relatively novel and not well established.
