Outcome Comparisons of Two Vibratory Positive Expiratory Pressure Devices in Patients Unable to Clear Airway Secretions

What this Trial Is About

Researchers are evaluating two different vibratory airway clearance devices in adults with airway clearance impairment who have difficulty clearing airway secretions. This pilot randomized control trial compares a device with a higher oscillatory index to one with a lower oscillatory index to see how well each helps clear airway secretions and affects other important clinical outcomes. The study focuses on patients admitted to an academic medical center who have a respiratory assess and treat (RAAT) score of at least 10 and a secretion score of at least 5. Participants will be randomly assigned to receive either the high oscillatory index device or the low oscillatory index device. Device assignment alternates monthly and the assigned device will be used as per hospital unit protocols by bedside clinical staff. Frequency of device use follows departmental guidelines. Patients will receive clinical evaluations using RAAT scores throughout their hospital stay. During the study, participants will be monitored until hospital discharge. Researchers will assess changes in RAAT scores, which measure respiratory rate, oxygen therapy, chest x-ray, secretion clearance, and vital capacity. Secondary measures include use of other respiratory interventions, ICU readmission, need for continuous positive pressure, and length of stay in the hospital and ICU. The trial aims to better understand how these devices impact respiratory function and patient outcomes in a hospital setting.
