Neurogenic pulmonary edema in the setting of critically ill neurologic patients is a condition that is not fully understood, and it is a relatively rare condition. Severe brain damage, such as cerebral and subarachnoid hemorrhage, head injuries and seizures, represents a risk factor for developing neurogenic pulmonary edema. Misdiagnosis and inappropriate management may worsen cerebral damage because of secondary brain injury from hypoxemia or reduced cerebral perfusion pressure. These factors may increase morbidity and mortality. This study aimed to review the current concepts on pathophysiologic mechanisms involved in the development of neurogenic pulmonary edema and discuss the associated clinical and therapeutic aspects.

Endogenous production of nitric oxide can be detected and monitored in exhaled air of men and animals. The main objective of this review was to discuss if nitric oxide in exhaled breath condensate is a useful tool when investigating respiratory dysfunctions in intensive care units. Specialized literature reveals an increasing interest in the use of exhaled breath condensate as a non-invasive method to investigate pulmonary disease. However, a standardized method for its collection is lacking, and use of different methods of respiratory support complicates comparison among different studies. In addition, the same specialized literature review emphasized possible difficulties for routine use of the exhaled breath condensate in intensive care patients, mainly under mechanical ventilation. Until exhaled breath condensate becomes a routine tool of research and monitoring of intensive care patients, more specific studies and technologies are still necessary. Its importance has been related to physiological control of the pulmonary function and to physiopathology of pulmonary disease involving chronic inflammation and oxidative stress.
