RAM Cannula for Non-Invasive Respiratory Support

The RAM Cannula is a specialized nasal interface designed to deliver non-invasive respiratory support to neonatal, infant, and pediatric patients. Unlike traditional CPAP prongs, the RAM Cannula uses a curved-prong design that fits comfortably in the nares while allowing clinicians to deliver a range of pressures and flow rates through standard ventilator or CPAP circuits — making it a versatile bridge between supplemental oxygen and full respiratory support.

In this collection you'll find the Neotech RAM Cannula (N4906), a large-size green PVC cannula built for both low and high flow applications. Its curved, non-flared prong tips are shaped to sit gently against delicate airway tissue, helping reduce the pressure-related skin breakdown and nasal trauma that fragile patients are prone to during extended wear. This version is supplied without tubing and is intended for single-patient use, which supports infection-control protocols in NICU and pediatric settings.

Selecting the right RAM Cannula comes down to matching prong size to the patient's nares — a proper fit is what allows the interface to seal effectively and deliver consistent flow without excessive leak. Clinicians typically size the cannula so the prongs occupy roughly two-thirds of the nostril, avoiding a tight seal that could increase pressure on the septum. Because the same device accommodates low- and high-flow therapy, it can adapt as a patient's respiratory needs change without swapping to an entirely different system.

These cannulas are commonly used in hospitals, NICUs, and specialized pediatric care units where gentle, adaptable non-invasive ventilation is essential. For related laboratory and diagnostic supplies from the same manufacturer family, browse our Ram Scientific collection.
