Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this study is to compare two different modes of noninvasive ventilation in hypercapnic respiratory failure. The investigators will compare AVAPS and BIPAP S/T and hypothesize that AVAPS will result in a decreased length of stay in the ICU or on telemetry. Currently, noninvasive ventilation is the standard of care for hypercapnic respiratory failure. However, the most effective mode for patients with hypercapnic respiratory failure is unclear.

1\. Overall Study Design and Plan

This is a single center, randomized trial that will include a total of 100 adult subjects aged 18 or older with hypercapnic respiratory failure of all etiologies (i.e. "all comers"). The investigators will randomize patients in a single-blinded (patient blinded) fashion to BIPAP S/T or AVAPS during the duration of their hospitalization. The investigators will assess ABG at baseline, 1 hour after initial placement on BIPAP S/T or AVAPS, and between hours 24-48 of use. The investigators will record the pre-NIV pH and PaCO2, post-NIV pH and PaCO2, length of hospital stay in the medical ICU or telemetry unit, days on NIV, need for intubation (if occurred), transition to medical ICU care in patients who were initially admitted to telemetry, and in-hospital mortality. All collected laboratory data are already done as part of usual care for all patients placed on NIV when a patient is on the telemetry unit or medical ICU. The groups will undergo stratified randomization based on whether they are initially admitted to medical ICU or medical telemetry. Patients from medical ICU or telemetry units will be randomized to one of the following arms:

Arm 1: AVAPS mode Arm 2 2: BIPAP S/T mode

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Average Volume-Assured Pressure Support (AVAPS)

Average Volume-Assured Pressure Support (AVAPS) setting on the noninvasive ventilator. The exact AVAPS setting will be titrated by the clinical team involved directly in the patient's care based on patient comfort and clinical response.

Group Type ACTIVE_COMPARATOR

Average Volume-Assured Pressure Support (AVAPS)

Intervention Type DEVICE

A setting on noninvasive ventilator that allows setting of maximum and minimum inspiratory pressure and sets a target tidal volume. The inspiratory pressure varies breath to breath to ensure pre-set tidal volume is delivered.

Bilevel Positive Airway Pressure Spontaneous Timed (BIPAP S/T)

Bilevel Positive Airway Pressure Spontaneous Timed (BIPAP S/T) setting on the noninvasive ventilator. The exact BIPAP S/T setting will be titrated by the clinical team involved directly in the patient's care based on patient comfort and clinical response.

Group Type ACTIVE_COMPARATOR

Bilevel Positive Airway Pressure Spontaneous Timed (BIPAP S/T)

Intervention Type DEVICE

A setting on noninvasive ventilator that allows setting of inspiratory pressure, inspiratory time, expiratory pressure, and backup rate to deliver variable tidal volumes.
