Pressure support ventilation (PSV) is a commonly used mode. It is patient-triggered, pressure-limited, and (normally) flow-cycled. Triggering difficulty occurring during PSV is usually due to intrinsic positive end-expiratory pressure. The airway pressure generated at the initiation of inhalation is determined by the pressure support setting and the pressure rise time (pressurization rate) sett...

BACKGROUND Strategies are needed to help prevent ventilator-associated pneumonia. OBJECTIVE To develop a ventilator bundle and care practices for nurses in critical care units to reduce the rate of ventilator-associated pneumonia. METHOD The ventilator bundle developed by the Institute for Healthcare Improvement was expanded to include protocols for mouth care and hand washing, head-of-bed ...

Many ventilators measure expired tidal volume (VT) without compensation either for the compliance of the ventilator circuit or for variations in the circuit setup. We hypothesized that the exhaled VT measured with a conventional ventilator at the expiratory valve would differ significantly from the exhaled VT measured with a pneumotachometer placed at the endotracheal tube. To investigate this ...

Since 2001, financial support has been provided for all patients with neuromuscular disease (NMD) who require ventilatory support due to the paralysis of respiratory muscles in Korea. The purpose of this study was to identify ventilator usage status and appropriateness in these patients. We included 992 subjects with rare and incurable NMD registered for ventilator rental fee support. From 21 F...

Deaths and injuries related to accidental ventilator disconnection occur in complex ways. A death related to accidental ventilator disconnection is presented from a subacute ventilator facility, and corrective action is discussed. Single-limb ventilators are now equipped with a flow-bypass coupling that prevents patient-side occlusion during disconnect and therefore prevents low-pressure alarm ...

abstract background : today, as many as 1.5 million americans use ventilators once in a year. .response to mechanical ventilation alarms remains to be one of the most challenging tasks facing physicians, nurses or other medical personnel in the icu. in the present study we aimed to compare the response times to “vocal alarms” and “visual or audible ones”. methods : in the present study we devel...

Objectives: The objectives of this post hoc analysis was to describe the characteristics of cardiopulmonary indicators among patients with normal ventilator weaning response and dysfunctional ventilator weaning response after coronary artery bypass graft surgery, and to find the differences in characteristics of cardiopulmonary indicators between patients with normal ventilator weaning response...

Mechanical ventilation can be life-saving for patients with acute respiratory failure. In between the 2 extremes of complete and no ventilatory support, both patient and machine contribute to ventilatory work. Ideally, ventilator gas delivery would perfectly match patient demand. This patient-ventilator interaction depends on how the ventilator responds to patient respiratory effort and, in tur...

We studied the effects of positive end-expiratory pressure (PEEP) applied by the ventilator on respiratory mechanics in ventilated patients with chronic obstructive pulmonary disease (COPD). Airway pressures, relaxed expiratory flow-volume curves and end-expiratory volumes (EEV) were measured. In all patients investigated without PEEP applied by the ventilator, an intrinsic PEEP level (PEEPi) a...

PURPOSE This study investigated the effects of physician education and the availability of Peso and PL data on physicians' decisions regarding ventilator management during specific simulated clinical conditions. MATERIALS AND METHODS The study was a prospective, before-after study using a case scenario-based questionnaire and a case simulator device comprising an Avea ventilator and an artifi...
