Image shows endotracheal tube, left subclavian central venous catheter in superior vena cava, and bilateral patchy opacities in mostly middle and lower lung zones. The main site of injury may be focused on either the vascular endothelium (eg, sepsis) or the alveolar epithelium (eg, aspiration of gastric contents). In the midst of a coronavirus disease 2019 (COVID-19) pandemic, a paucity of data precludes derivation of COVID-19-specific recommendations for nutrition therapy. Symptoms include shortness of breath (dyspnea), rapid breathing (tachypnea), and bluish skin coloration (cyanosis). 2011 May 1. 276(11):889-97. In a study comparing DcR3, soluble triggering receptor expressed on myeloid cells (sTREM)-1, TNF-alpha, and IL-6 in ARDS patients, plasma DcR3 levels were the only biomarker to distinguish survivors from nonsurvivors at all time points in week 1 of ARDS. 100 Schwill M, Tamaskovic R, Gajadhar AS, Kast F, White FM and Plückthun A: Systemic analysis of tyrosine kinase signaling reveals a common adaptive response program in a HER2-positive breast cancer.

This month marks the 50th anniversary of the first description of the condition now termed the acute respiratory distress syndrome, or ARDS. Alveoli already damaged by ARDS may experience further injury from the shear forces exerted by the cycle of collapse at end-expiration and reexpansion by positive pressure at the next inspiration (so-called atelectrauma). Guerin C, Reignier J, Richard JC, Neuret P, PROCENA Study Group. Am J Respir Crit Care Med. The guideline was a joint project with the Intensive Care Society and the recommendations are supported by the British Thoracic Society. J Intensive Care Med. ARDS causes a marked increase in intrapulmonary shunting, leading to severe hypoxemia. Injury to the alveolar lining cells also promotes pulmonary edema formation. ARDS can occur in a variety of clinical situations, including pneumonia, sepsis, pancreatitis, blood transfusion. 354(24):2564-75. Chances of survival and recovery are better for those who recover before other organs begin to fail. Approximately 20% of patients with ARDS have no identified risk factor. 2011 Feb 17.

This is a high-risk therapy with many potential complications. Injury to the endothelium results in increased capillary permeability and the influx of protein-rich fluid into the alveolar space. ARDS risk factors include direct lung injury (most commonly aspiration of gastric contents), systemic illnesses, and injuries. The AECC defined ARDS as an acute condition characterized by bilateral pulmonary infiltrates and severe hypoxemia in the absence of evidence for cardiogenic pulmonary edema. ARDS expresses itself as an inhomogeneous process. Lung protective low-tidal-volume ventilation, high PEEP and permissive hypercapnea are the key features of a successful approach. [Full Text]. Studies (2017) on the ARDSNet patient cohort have identified at least two major subgroups based on immune response and physiologic presentation. N Engl J Med. Ventilator-associated lung injury in patients without acute lung injury at the onset of mechanical ventilation. Patients with ARDS are likely to have prolonged hospital courses, and they frequently develop nosocomial infections, especially ventilator-associated pneumonia (VAP). Chest. Prevalence and prognosis of shunting across patent foramen ovale during acute respiratory distress syndrome. Acute respiratory distress syndrome (ARDS) is a serious lung condition that causes low blood oxygen. Hence, a variety of insults resulting in damage either to the vascular endothelium or to the alveolar epithelium could result in ARDS. [Medline].
