Even after many years of intensive research acute respiratory distress syndrome (ARDS) is still associated with a high mortality. Epidemiologically, ARDS represents a central challenge for modern intensive care treatment. ⋯ Lung protective mechanical ventilation and adjuvant therapies, such as the prone position and targeted extracorporeal lung support are of particular importance in the treatment of ARDS, depending on the severity of the disease. In order to guarantee an individualized and needs-adapted treatment, ARDS patients benefit from treatment in specialized centers.

Diaphragm Muscle Thinning in Subjects Receiving Mechanical Ventilation and Its Effect on Extubation.
Diaphragm muscle weakness and atrophy are consequences of prolonged mechanical ventilation. Our purpose was to determine whether thickness of the diaphragm (TDI) changes over time after intubation and whether the degree of change affects clinical outcome. ⋯ Although most of the subjects showed evidence of diaphragm thinning, we were unable to find a correlation with outcome of extubation failure. In fact, the thinner the diaphragm at baseline and the greater the extent of diaphragm thinning at 72 h, the greater the likelihood of extubation. Thickening ratio or other measurement may be a more reliable indicator of diaphragm dysfunction and should be explored.

A Study on the Psychometric Properties of Revised-nonverbal Pain Scale and Original-nonverbal Pain Scale in Iranian Nonverbal-ventilated Patients.
The nonverbal pain scale is one of the instruments which study pain in nonverbal-ventilated patients with regard to the changes of behavioral and physiological indices. The purpose of the study is to survey the psychometric properties of revised-nonverbal pain scale (R-NVPS) and original-nonverbal pain scale (O-NVPS) in ventilated patients hospitalized in critical care units. ⋯ R-NVPS and O-NVPS can both be used as valid and reliable scales in studying pain in ventilated patient. However, in comparing the items, "respiration" (R-NVPS) had a higher sensitivity than "physiology II" (O-NVPS) in assessing pain.

The positive end-expiratory pressure (PEEP), since its introduction in the treatment of acute respiratory failure, up to the 1980s was uniquely aimed to provide a viable oxygenation. Since the first application, a large debate about the criteria for selecting the PEEP levels arose within the scientific community. Lung mechanics, oxygen transport, venous admixture thresholds were all proposed, leading to PEEP recommendations from 5 up to 25 cmH2O. ⋯ In fact, all the other methods estimate as recruitment the gas entry in pulmonary units already open at lower PEEP, but increasing their compliance at higher PEEP. Since higher PEEP is usually more indicated (also for oxygenation) when the recruitability is higher, as occurs with increasing severity, a meaningful PEEP selection requires the assessment of recruitment. The Berlin definition may help in this assessment.

Early mobilization protocols have been successfully implemented to improve function in critically ill patients; however, no study has focused on the oncology population. ⋯ Early mobilization appears feasible in addressing the cognitive and functional needs of oncology patients in the intensive care unit.
