MECHANICAL VENTILATION USING artificial airways such as endotracheal and tracheostomy tubes has many complications (Morán et al 2006). Appropriate humidification of inspired air is one of the components of the high impact interventions for mechanically ventilated patients (Department of Health (DH) 2007). High impact interventions are part of the care bundle approach that aims to prevent ventilator-associated pneumonia (National Institute for Health and Clinical Excellence (NICE) 2008). Although the provision of heat and humidity for the airways of mechanically ventilated patients is standard practice worldwide, there is considerable confusion among healthcare professionals on what constitutes optimal humidity and how to provide it (Ricard 2007). This article aims to provide readers with an understanding of why artificial Artificial humidification for the mechanically ventilated patient
The administration of sedatives may present several challenges for critical care nurses. Evidence-based practice requires critical care nurses to remain up to date with developments in sedation management and ensure safe and effective use of sedative agents in their practice. Dexmedetomidine is a sedative drug that has been increasingly used in the intensive care setting in recent years. This article provides an overview of the pharmacological properties of dexmedetomidine and discusses nurses' responsibilities in caring for patients receiving dexmedetomidine infusion.
