ReviewDiagnostic strategy for oncology patients with acute respiratory failure.
Acute respiratory failure (ARF) is frequent and often fatal in patients with a malignancy. However, there is not one type of "oncology patient", and it's high time that both clinical management and further studies consider specific populations rather than the heterogeneous and artificial group of "cancer patients". ⋯ These non invasive tools have reduced but not weakened the value of fiberoptic bronchoscopy and bronchoalveolar lavage: some subsets of patients may always benefit from this technique, particularly when new protective strategies such as non invasive mechanical ventilation and target-controlled infusion of sedative drugs are used. The present review focuses on the personalised approach required in "oncology patients" with ARF, based on first identifying the pattern of immunodeficiency, then listing the most probable hypotheses in the light of clinical and radiological findings in order to, finally, select the most accurate diagnostic tools.

Review Meta AnalysisA systematic technical review of the systems for the continuous positive airway pressure.
Continuous positive airway pressure (CPAP) is the application in the airways of continuous positive pressure, close to the positive end expiratory pressure. The two common available systems are by a continuous (high/low) flow system and by a mechanical ventilator. Aim of this study was to compare the mechanical performance of the CPAP systems in intubated and not intubated patients. ⋯ The continuous flow systems are able to maintain acceptable airway pressure variations during normal breathing. The most recent mechanical ventilators equipped with flow by systems compared to the first one, presented a similar or better work of breathing compared to the continuous flow systems due to the application of a little amount of pressure support. Although the use of a continuous flow is cheaper compared to mechanical ventilators, it does not allow a continuous respiratory monitoring.

Multicenter StudyEffectiveness and predictors of success of noninvasive ventilation during H1N1 pandemics: a multicenter study.
The use of non-invasive ventilation (NIV) in acute hypoxemic respiratory failure (AHRF) due to H1N1 virus infection is controversial. In this multicenter study we aimed to assess the efficacy of NIV in avoiding endotracheal intubation (ETI) and to identify predictors of success or failure. ⋯ The early application of NIV, with the aim to avoid invasive ventilation, during the H1N1 pandemics was associated with an overall success rate of 47/98 (48%). Patients presenting at admission with an high SAPS II score and a low PaO(2)/FiO(2) ratio and/or unable to promptly correct gas exchange are at high risk of intubation and mortality.
