Initiation of Noninvasive Ventilation for Sleep Related Hypoventilation Disorders: Advanced Modes and Devices

Abstract

Although noninvasive ventilation (NIV) has been used since the 1950s in the polio epidemic, the development of modern bilevel positive airway pressure (BPAP) devices did not become a reality until the 1990s. Over the past 25 years, BPAP technology options have increased exponentially. The number of patients receiving this treatment both in the acute setting and at home is growing steadily. However, a knowledge gap exists in the way the settings on these devices are adjusted to achieve synchrony and match the patient's unique physiology of respiratory failure. This issue is further complicated by differences in pressure and flow dynamic settings among different types of NIV devices available for inpatient and home care.
