Can I Use Cannulaide® with Vapotherm®?
Cannulaide® is a transparent adhesive designed to relieve irritation of the nares in neonates who are placed on nasal CPAP. The product creates an air seal to support the pressure mechanism of CPAP while ensuring that the cannula prongs do not fully occlude the neonate’s nares and thereby don’t lead to a potential Hospital Acquired Pressure Injury (HAPI). While Vapotherm’s high velocity therapy is a viable alternative to Non-Invasive Positive Pressure Ventilation (NIPPV), Vapotherm’s mechanism of action is not pressure-based[1,2] and therefore we strongly recommend against the use of cannulaide with Vapotherm cannulas.
Air egress is a crucial component of the ventilatory effect that high velocity therapy achieves which is why there must be no air seal on Vapotherm’s cannulas.[3,4,5] Vapotherm manufactures five different cannula sizes for the neonate population (and an additional three for the adult and pediatric population) in order to ensure that clinicians can select a cannula size that does not occlude more than 50% of the nares.
While a small amount of positive end-expiratory pressure (PEEP) is generated on high velocity therapy, the space around Vapotherm prongs is needed for efficacious flushing of the nasopharyngeal dead space. High velocity therapy and its mechanism of action has been found to have similar clinical efficacy to NIPPV in the neonatal and adult populations for management of respiratory distress. Neither Cannulaide, nor any other air seal, was used in these studies.[1,2]
