👉 The NR fluid, or Non-Returnable Fluid, is a term used in the context of non-invasive ventilation (NIV) therapies, particularly in the treatment of respiratory conditions like COPD and sleep apnea. It refers to a specialized, low-pressure gas mixture that is delivered through a mask to support breathing without the need for the patient to physically return to the ventilator. This fluid is designed to improve lung function, reduce work of breathing, and enhance oxygenation by assisting in the expansion of the lungs and preventing alveolar collapse. Unlike traditional NIV, which requires patients to breathe through a mask while the ventilator provides positive pressure, the NR fluid allows for more natural breathing patterns, making it a gentler and often more tolerable option for patients.
