Gravity ventilators rely simply on air buoyancy to extract air and are widely used to exhaust air contaminants and heat from workplaces using minimal energy. They are designed to maximize the exhaust flow rate, but the rain penetration sometimes causes malfunctioning. In this study, the characteristics of rain penetration through a ventilator were examined as a preliminary study to develop a ve...

OBJECTIVE To determine the efficacy of vital capacity (VC) and a proposed ventilator requirement index (VRI) for justifying ventilator prescription and use for patients with neuromuscular/chest wall diseases (NMD). DESIGN Prospective observational study in which 319 patients with NMD, including 187 ventilator users, were separated into four groups: (1) asymptomatic, (2) abnormal specific scre...

OBJECTIVE To evaluate the data quality of ventilator settings recorded by respiratory therapists using a computer charting application and assess the impact of incorrect data on computerized ventilator management protocols. DESIGN An analysis of 29,054 charting events gathered over 12 months from 678 ventilated patients (1,736 ventilator days) in four intensive care units at a tertiary care hos...

THE RELATIONSHIP BETWEEN ENTERAL NUTRITION FORMULA COMPOSITION, FEEDING TUBE PLACEMENT SITE, AND THE START OF ENTERAL FEEDINGS ON THE DEVELOPMENT OF VENTILATOR ASSOCIATED EVENT IN AN ADULT INTENSIVE CARE UNIT by Jessica M. Alexander Background: Ventilator associated pneumonia (VAP) is a major cause of morbidity, longer intensive care unit (ICU) stay, increased duration of mechanical ventilation...

Ventilator-Associated Pneumonia (VAP) is a type of nosocomial infection that mostly occurs in intensive care units, generally occurring 48 hours after intubation. Endotracheal intubation and the use mechanical ventilator are invasive measures by patients, having therapeutic effect. This paper aimed to identify oral hygiene materials for incidence pneumonia related ventilator. The research desig...

When supplementary oxygen is necessary with nasal intermittent positive pressure ventilation (NIPPV), the optimal route by which it should be added to the ventilator circuit is unknown. We investigated the oxygen concentration received when oxygen was supplied at flow rates between 0 and 6 L.min-1 into the proximal ventilator tubing or the nasal mask whilst patients were ventilated with air. El...

Ventilator management of a patient who is recovering from acute respiratory failure must balance competing objectives. Discontinuing mechanical ventilation and removing the artificial airway as soon as possible reduces the risk of ventilator-induced lung injury, nosocomial pneumonia, airway trauma from the endotracheal tube, and unnecessary sedation, but premature ventilator-discontinuation or ...

BACKGROUND Eye care is an essential component in the management of critically ill patients. Standardized eye care can prevent corneal complications in ventilated patients. OBJECTIVE This study was designed to compare old and new practices of corneal care for reduction in corneal complications in ventilated patients. METHODS This study was done in three phases each of six month duration. Pha...

Compared with invasive ventilation, non-invasive ventilation (NIV) has two unique characteristics: its non-hermetic nature and the fact that the ventilator-lung assembly cannot be considered as a single-compartment model because of the presence of variable resistance represented by the upper airways. When NIV is initiated, the ventilator settings are determined empirically based on clinical eva...
