Review Case Reports
Emergency bedside extracorporeal membrane oxygenation for rescue of acute tracheal obstruction.
A 39-year-old man experienced total obstruction of a distal tracheal plastic stent by a tumor mass, preventing effective ventilation and resulting in cardiac arrest. Resuscitation by emergency bedside venoarterial extracorporeal membrane oxygenation (ECMO) permitted time to physically remove the obstructing tumor and reestablish successful ventilation and liberation from ventilatory support. We review several other reported cases of emergency ECMO to resuscitate patients with acute airway obstruction.

For the busy clinician, educator, or manager, it is becoming an increasing challenge to filter the literature to what is relevant to one's practice and then update one's practice based on the current evidence. The purpose of this paper is to review the recent literature related to long-term oxygen therapy, pulmonary rehabilitation, airway management, acute lung injury and acute respiratory distress syndrome, respiratory care education, and respiratory care management. These topics were chosen and reviewed in a manner that is most likely to have interest to the readers of Respiratory Care.

Review Meta Analysis
Diagnostic accuracy of endobronchial ultrasound-guided transbronchial needle biopsy in mediastinal lymphadenopathy: a systematic review and meta-analysis.
To perform a systematic review and meta-analysis of prospectively conducted studies to define diagnostic performance of endobronchial ultrasound-guided transbronchial needle biopsy (EBUS-TBNB) in mediastinal and hilar lymphadenopathy. ⋯ Evidence of moderate quality confirms the high diagnostic performance of EBUS-TBNB for mediastinal and hilar lymphadenopathy, both in malignant and non-malignant conditions. Available evidence also demonstrates the safety of this procedure.

The bedside chest x-ray (CXR) is an indispensible diagnostic tool for monitoring seriously ill patients in the intensive care unit. The CXR often reveals abnormalities that may not be detected clinically. ⋯ The interpretation of the bedside CXRs is often challenging, and requires extensive radiologic experience to avoid misinterpretation of the wide spectrum of pleural and pulmonary disease. The clinical information is of substantial value for the interpretation of the frequently nonspecific findings.

Airway pressure release ventilation (APRV) is inverse ratio, pressure controlled, intermittent mandatory ventilation with unrestricted spontaneous breathing. It is based on the principle of open lung approach. It has many purported advantages over conventional ventilation, including alveolar recruitment, improved oxygenation, preservation of spontaneous breathing, improved hemodynamics, and potential lung-protective effects. ⋯ Also, they should be familiar with the differences between APRV, biphasic positive airway pressure (BIPAP), and other conventional and nonconventional modes of ventilation. There is no solid proof that APRV improves mortality; however, there are ongoing studies that may reveal further information about this mode of ventilation. This paper reviews the different methods proposed for APRV settings, and summarizes the different studies comparing APRV and BIPAP, and the potential benefits and pitfalls for APRV.
