The escalating number of emergency department (ED) visits, length of stay, and hospital overcrowding have been associated with an increasing number of critically ill patients cared for in the ED. Existing physiologic scoring systems have traditionally been used for outcome prediction, clinical research, quality of care analysis, and benchmarking in the intensive care unit (ICU) environment. However, there is limited experience with scoring systems in the ED, while early and aggressive intervention in critically ill patients in the ED is becoming increasingly important. ⋯ A few existing ICU physiologic scoring systems have been applied in the ED, with some success. Other ED specific scoring systems have been developed for various applications: recognition of patients at risk for infection; prediction of mortality after critical care transport; prediction of in-hospital mortality after admission; assessment of prehospital therapeutic efficacy; screening for severe acute respiratory syndrome; and prediction of pediatric hospital admission. Further efforts at developing unique physiologic assessment methodologies for use in the ED will improve quality of patient care, aid in resource allocation, improve prognostic accuracy, and objectively measure the impact of early intervention in the ED.

How good is the care patients receive during interhospital transfer? The results of a study in this journal make for some disturbing reading. Adverse events occur in about one-third of cases. ⋯ So how do we make things better? All transfer equipment needs to be standardized and be "fit-for-purpose". Each hospital needs to take responsibility for the quality of care received in transfer, and this should include guidelines, training and equipment.

Delirium is a frequently occurring but often under-diagnosed and under-treated problem in the intensive care unit (ICU). It has been linked to adverse outcome, increased length of stay and higher mortality in critically ill patients. A study by Thomason and coworkers published in this issue of Critical Care deals with the issue of delirium and its consequences in less severely ill patients. This commentary aims to provide context for this study, discussing its potential implications as well as the potential therapeutic and preventive measures in patients with hyperactive or hypoactive delirium.

We observed an oscillatory flow while ventilating critically ill patients with the Dräger Oxylog 3000 transport ventilator during interhospital transfer. The phenomenon occurred in paediatric patients or in adult patients with severe airway obstruction ventilated in the pressure-regulated or pressure-controlled mode. As this had not been described previously, we conducted a bench study to investigate the phenomenon. ⋯ Oscillatory flow with potentially harmful effects may occur during ventilation with the Dräger Oxylog 3000, especially in conditions with high resistance such as small airways in children (endotracheal tube internal diameter <6 mm) or severe obstructive lung diseases or airway diseases in adult patients.

Lobar atelectasis is a common problem caused by a variety of mechanisms including resorption atelectasis due to airway obstruction, passive atelectasis from hypoventilation, compressive atelectsis from abdominal distension and adhesive atelectasis due to increased surface tension. However, evidence-based studies on the management of lobar atelectasis are lacking. ⋯ Chest physiotherapy, nebulised DNase and possibly fibreoptic bronchoscopy might be helpful in patients with mucous plugging of the airways. In passive and adhesive atelectasis, positive end-expiratory pressure might be a useful adjunct to treatment.
