Efficacy Of Combined Nebulized Hypertonic Saline and Chest Percussion Therapy in Acute Viral Bronchiolitis

February 2, 2026 updated by: NYU Langone Health

A Pilot, Non-randomized, Single-site Clinical Study Investigating the Efficacy of Combined Therapy of Nebulized 3% Hypertonic Saline and Chest Percussion Therapy in Pediatric Patients With Acute Viral Bronchiolitis.

This study will examine the efficacy of combined nebulized hypertonic saline with chest percussion therapy in patients age 0 to 24 months admitted to the general inpatient pediatrics unit with acute bronchiolitis. 3% nebulized hypertonic saline treatments combined with 3 minutes of chest percussion therapy will be administered every 6 hours of patients selected for the study.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

In order to be eligible to participate in this study (experimental arm), an individual must meet all of the following criteria:

  • Age 0 to 24 months
  • Admitted to the general inpatient pediatrics unit

  • Age 0 to 24 months
  • Admitted to the general inpatient pediatrics unit
  • Has a diagnosis of acute bronchiolitis
  • Receiving supplemental oxygen support

Exclusion Criteria:

An individual who meets any of the following criteria will be excluded from participation in this study:

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Nebulized Hypertonic Saline + Chest Percussion Therapy
Participants with acute viral bronchiolitis will receive 3% nebulized hypertonic saline treatments combined with 3 minutes of chest percussion therapy. This will be administered every 6 hours.
Drug: Nebulized 3% sodium chloride solution
Standardized dose of nebulized 3% sodium chloride will be provided from 4 mL vial and administered be every 6 hours.
Device: Chest percussion cups
The chest percussion cup is a small, flexible cup made of vinyl that is used to provide gentle chest wall vibrations to assist with airway clearance and is utilized in patients of all ages with sputum production, such as those with acute bronchiolitis. Administered every 6 hours while on supplemental oxygen therapy.
Other Names:
  • MC-2247 Pediatric Manual Percussor Cup
No Intervention: Control Arm
Participants in the control arm will be analyzed via retrospective chart review; these participants will not be consented nor enrolled in the trial.
