The small one-pound control unit, running with wall oxygen in the hospital and used with the low-profile nasal interface, allows use in many parts of the hospital: the emergency department, medical-surgical recovery, general floors and post-ventilator weaning support. The Life2000 device’s nasal pillows conform to the nostril, creating a seal that prevents leakage while eliminating the risk of nasal bridge skin breakdown and the formation of mask pressure ulcers from prolonged periods of NIV usage.
