Imagine the Ventilatory Support of NiPPV with the Comfort of Humidified High Flow

Clinicians admitting patients in respiratory distress traditionally have three categories of tools to relieve symptoms. There is oxygen therapy for low severity patients, non-invasive positive pressure ventilation (NiPPV) for moderate distress, and then mechanical ventilation for severe cases of respiratory distress. Thanks to Hi-VNI® Technology, clinicians now have a new tool to treat a broad range of patients experiencing undifferentiated respiratory distress.

Hi-VNI Technology offers a solution for the drawbacks of commodity high flow oxygen systems and NiPPV systems.
Traditional Treatment Continuum
Some of the advantages of tools like commodity high flow oxygen systems are that they offer humidified gases and tend to be more comfortable for patients than mask-based therapies. On the other hand, mask- and pressure-based therapies, like NiPPV, have been shown to be effective at treating hypercapnic patients in addition to relieving hypoxia. Therefore, NiPPV is often a go-to therapy for patients presenting in the Emergency Department with undifferentiated respiratory distress when clinicians want to quickly stabilize a patient without immediately knowing whether they are hypercapnic, hypoxemic, or a combination of the two.

However, patients may have difficulty tolerating mask-based interfaces, and about a third of NiPPV failure is attributed to mask-intolerance.11. Carron M. et al. Complications of non-invasive ventilation techniques: a comprehensive qualitative review of randomized trials. British Journal of Anaesthesia. 110(6):896-914. (2013) https://www.ncbi.nlm.nih.gov/pubmed/23562934Read Full Text These patients may be able to better tolerate the cannula interface of commodity high flow oxygen products. However, studies using those products generally don’t include patients with hypercapnia.2,32. Frat, Jean-Pierre, Rémi Coudroy, Nicolas Marjanovic, and Arnaud W.

This leaves clinicians without a simple solution for the mask-intolerant patient in undifferentiated respiratory distress.

Hi-VNI Technology is one tool that combines the appealing benefits of both of these systems: a mask-free, comfortable interface and the clinical efficacy of NiPPV.
Redefined Treatment Continuum
Hi-VNI Technology has been clinically proven to be a viable alternative to NiPPV in the treatment of undifferentiated respiratory distress in adults, including hypercapnia.44. Doshi, Pratik et al.

Annals of Emergency Medicine, 2018. https://www.ncbi.nlm.nih.gov/pubmed/29310868Read Full Text When it comes to the neonatal population, Hi-VNI Technology has also been demonstrated to have comparable outcomes to NCPAP and bi-level PAP.55.

Although Hi-VNI Technology operates in part based on L/min selection, it is not a commodity high flow oxygen system, and although it can offer ventilatory support, its primary mechanism of action is velocity not pressure. Instead, Hi-VNI Technology is mask-free NIV™ for spontaneously breathing patients.
