The Pressure Safe High Flow Cannula is designed to monitor high pressure changes that may cause barotrauma conditions. A unique pressure limiting Pop-O feature prevents airway pressure from exceeding 21 cm H2O. The required pressure phases of high ow therapy are now clearly controlled and observed with Pressure Safe. In addition, the Comfort Soft Plus® patented elastomeric formulation minimizes cannula friction on the patient skin area. This produces a greater wear comfort and safeguards against epidermal stripping that can occur from traditional PVC cannula and/or adhesive securement tape use
