Abstract: A portable nasal ventilation assembly and system having a nasal piece with fluid delivery ports which engage and occlude the nares of a patient and provides sustained oxygen saturations greater than 90% with lung afflictions requiring high-flows such as Pulmonary Fibrosis. The assembly is noninvasive and does not require the use of positive pressure machines that can only be used within the confines of a hospital intensive care unit. It can be used on patients with different respiratory problems. Patients on the system can be home while awaiting further hospital treatment, such as (for example) a lung transplant, for a fraction of the cost of a hospital stay. Although the system does not replace ventilator devices, it is effective for spontaneously breathing patients that require ventilators to maintain an adequate life sustaining oxygen level. The device allows for portability and can reduce hospital stay and cost dramatically.
