The physiologic effects of noninvasive ventilation.
The physiologic effects of noninvasive ventilation (NIV) on work of breathing (WOB) and breathing pattern, respiratory-system mechanics, and hemodynamic function were examined via a literature review of clinical studies done between 1990 and 2008. Forty-one relevant studies were found; the majority examined patients with chronic obstructive pulmonary disease, whereas some also included patients...
متن کاملComparative physiologic effects of noninvasive assist-control and pressure support ventilation in acute hypercapnic respiratory failure.
STUDY OBJECTIVE To compare the effects of noninvasive assist-control ventilation (ACV) and pressure support ventilation (PSV) by nasal mask on respiratory physiologic parameters and comfort in acute hypercapnic respiratory failure (AHRF). DESIGN A prospective randomized study. SETTING A medical ICU. PATIENTS AND INTERVENTIONS Fifteen patients with COPD and AHRF were consecutively and rand...
متن کاملNoninvasive ventilation.
Endotracheal intubation and mechanical ventilation have traditionally been employed in patients with acute respiratory insufficiency. However, this form of management can have serious adverse effects, mainly infections and barotrauma. Noninvasive ventilation (NIV) has been shown to be an effective alternative, as it reduces both the frequency of complications and cost of care. In fact, NIV is c...
متن کاملPhysiologic evaluation of different levels of assistance during noninvasive ventilation delivered through a helmet.
OBJECTIVE To evaluate the effects of various levels of pressure support (PS) during noninvasive ventilation delivered through a helmet on breathing pattern, inspiratory effort, CO2 rebreathing, and comfort. DESIGN Physiologic study. SETTING University-affiliated hospital. PATIENTS AND PARTICIPANTS Eight healthy volunteers. INTERVENTIONS Volunteers received ventilation through a helmet w...
متن کاملNew setting of neurally adjusted ventilatory assist for noninvasive ventilation by facial mask: a physiologic study
BACKGROUND Noninvasive ventilation (NIV) is generally delivered using pneumatically-triggered and cycled-off pressure support (PSP) through a mask. Neurally adjusted ventilatory assist (NAVA) is the only ventilatory mode that uses a non-pneumatic signal, i.e., diaphragm electrical activity (EAdi), to trigger and drive ventilator assistance. A specific setting to generate neurally controlled pre...
