Compact. Reliable. Ready for Care Anywhere.

The O-Two^® Mesh Nebulizer is a portable aerosol delivery device designed for EMS, transport medicine, respiratory therapy, emergency care, and acute care environments. Using active vibrating mesh technology, it converts prescribed liquid medication into a fine, consistent aerosol for inhalation therapy without requiring compressed gas.

Suitable for hospitals, clinics, ambulances, and prehospital settings, the O-Two^® Mesh Nebulizer supports medication delivery at the bedside, during patient transport, or in fast-paced emergency care environments. Its compact, battery-powered design allows clinicians to deliver aerosol therapy without dependence on wall air or oxygen sources, helping preserve oxygen supplies for patient oxygenation when resources are limited.

Clinically Proven Aerosol Performance

At the core of the O-Two^® Mesh Nebulizer is a vibrating mesh membrane that aerosolizes liquid medication through precision micro-apertures. Compared with conventional jet nebulizers, vibrating mesh technology has been shown to provide higher aerosol delivery efficiency, lower residual medication volume, and a greater proportion of medication available for inhalation. These advantages help support efficient drug delivery while reducing medication waste.

Evidence-Based Advantages for Emergency and Acute Care

Because the O-Two^® Mesh Nebulizer does not require oxygen or compressed air to generate aerosol, it helps conserve oxygen resources and simplifies treatment setup in transport and acute care environments. Clinical and laboratory studies have demonstrated higher delivered doses, shorter treatment times, and more efficient aerosol delivery with vibrating mesh nebulizers compared with traditional jet nebulizers.

Whether in a hospital, clinic, ambulance, or prehospital setting, the O-Two^® Mesh Nebulizer provides healthcare professionals with a compact, transport-ready solution for efficient aerosol therapy across the continuum of care.

Combining CPAP Therapy with Next-Generation Nebulization

When paired with the O-Two® Single-Use CPAP system, the O-Two® Mesh Nebulizer delivers a powerful combination of non-invasive respiratory support and efficient aerosol therapy. Its active vibrating mesh technology produces a fine, consistent aerosol from prescribed liquid medications without requiring compressed air or additional oxygen to generate the aerosol, helping conserve valuable oxygen resources while supporting efficient medication delivery.

The CPAP system’s open-circuit design allows nebulizer treatments to be provided in-line between the face mask and CPAP unit, enabling respiratory support and aerosol therapy to be administered simultaneously without interrupting treatment. Together, these technologies provide clinicians with a compact, portable and streamlined solution for delivering respiratory care in emergency, prehospital, transport and acute-care environments.
