The aim of the study is to assess, in patients with acute hypoxemic respiratory failure, the short term physiologic effects of the high flow oxygen nasal therapy (Optiflow), in term of inspiratory muscle effort, gas exchange, comfort and dyspnea
The administration of a known concentration of oxygen is an important part of routine care of the patient admitted in intensive care unit for acute hypoxemic respiratory failure. A new high flow oxygen delivery system (Fisher and Paykel Health care) has been developed (Optiflow). The system used a heated humidifier and heated breathing circuit via a nasal interface. High flow nasal therapy (Optiflow) is associated with the generation of significant positive airway pressure in healthy volunteers. Positive expiratory pressure may have a number of benefits in respiratory failure which include improved ventilation/perfusion matching with improved oxygenation, reduced airways resistance and reduced work of breathing. Moreover high flow nasal therapy may improve oxygen administration by decreasing oxygen dilution, decreasing death space and using high levels of humidification

Nasally applied continuous positive airway pressure (CPAP) therapy, acting as a pneumatic splint, is a remarkably effective treatment for obstructive sleep apnea (OSA), a therapy that rescues patients...
The purpose of this review is to provide an overview on how interactions between control of breathing, respiratory load, and muscle function may lead to respiratory failure. The mechanisms involved va...
Endocan, a component of the endothelial glycocalyx (EG), has been linked with respiratory failure in sepsis. This study explored the temporal patterns of three EG biomarkers, including endocan, and th...
Although 1-year survival in medically critically ill patients with prolonged mechanical ventilation is less than 50%, the relationship between respiratory failure after trauma and 1-year mortality is ...
Respiratory support system used primarily with rates of about 100 to 200/min with volumes of from about one to three times predicted anatomic dead space. Used to treat respiratory failure and maintain ventilation under severe circumstances.
Application of a life support system that circulates the blood through an oxygenating system, which may consist of a pump, a membrane oxygenator, and a heat exchanger. Examples of its use are to assist victims of smoke inhalation injury, respiratory failure, and cardiac failure.
Acute respiratory illness in humans caused by the Muerto Canyon virus whose primary rodent reservoir is the deer mouse Peromyscus maniculatus. First identified in the southwestern United States, this syndrome is characterized most commonly by fever, myalgias, headache, cough, and rapid respiratory failure.
