Category: Critical Care Nursing Positive-pressure mechanical ventilatory support is an essential component in the life support of patients with respiratory failure. However, it is...
Category: Critical Care Nursing Because diseased lung units require higher pressures to open than to keep open, additional recruitment can sometimes be provided by the use of recru...
Category: Critical Care Nursing In patients with respiratory failure on VV-ECMO, right ventricular failure can occur due to pulmonary fibrosis and increased pulmonary vascular resi...
Category: Critical Care Nursing Ventilator-induced lung injury is often a regional phenomenon that occurs when low-resistance/high-compliance units receive a disproportionately hi...
Category: Critical Care Nursing The major goals of mechanical ventilation with positive pressure are to unload the ventilatory muscles and to optimize ventilation-perfusion matchin...
Category: Critical Care Nursing Volume repletion can be used, if appropriate, to maintain cardiac output in the setting of high intrathoracic pressure. Lung distention can increase...
Category: Critical Care Nursing Other positive-pressure ventilation regional injuries include: Pericardium (pneumopericardium), subcutaneous tissue (subcutaneous emphysema), pleura...
Category: Critical Care Nursing In VV ECMO, the native heart must deliver oxygenated flow to the systemic circulation. VV requires adequate cardiac function. Venous blood is divert...
Category: Critical Care Nursing Mechanical ventilation complications include lung injury, cardiac compromise, oxygen toxicity and patient discomfort. Applying support requires trad...
Category: Critical Care Nursing Patients can interact with all three phases of an assisted breath: (1) trigger, (2) flow delivery and (3) cycle. Triggering dyssynchronies can be at...
Category: Critical Care Nursing With ECMO in venoarterial mode, deoxygenated blood is removed from the venous system and pumped to a membrane lung, which removes carbon dioxide and...
Category: Critical Care Nursing The lung can be injured when it is stretched excessively by positive-pressure ventilation. Historically, the most well-recognized injury was alveola...
Category: Critical Care Nursing In harlequin” or “north-south” syndrome, methods to improve upper body oxygenation include placing another venous cannula into the right atrium, the...
Category: Critical Care Nursing In addition to affecting ventilation, intrathoracic pressure changes resulting from positive-pressure ventilation can affect cardiovascular function...
Category: Critical Care Nursing Because parenchymal lung injury is often heterogeneous, appropriate PEEP in one region may be suboptimal in another. Optimizing PEEP is a balance be...
Category: Critical Care Nursing In ECMO, if desaturated blood from the left heart is primarily perfusing the upper body, this results in a cyanotic upper body with a well-perfused...
Category: Critical Care Nursing In mechanical ventilation, managing dyssynchronies can be challenging. Careful adjustments of flow magnitude, timing and patterns (especially the us...
Category: Critical Care Nursing Mechanically ventilated patients are at an increased risk of pulmonary infections. One reason is that the endotracheal tube impairs the cough reflex...
Category: Critical Care Nursing In veno-venous ECMO, deoxygenated blood is removed from the venous system and sent via an external pump to the membrane lung where oxygen is added a...
Category: Critical Care Nursing In ECMO patients with severe respiratory failure who are femoral artery cannulated, differential oxygen saturations of the upper and lower extremiti...
Category: Critical Care Nursing Mechanically ventilated patients are at an increased risk of pulmonary infections. One reason is that the ICU environment, with its heavy antibiotic...
Category: Critical Care Nursing Extracorporeal membrane oxygenation modes are named for the sites from which the blood is drained and returned. There are two major types, venoarter...
Researchers develop device that continuously tracks key indicators of lung health, providing transplant teams with more detailed information than current hourly testing. An organ t...
