Prognostic value of pulmonary dead space in patients with the acute respiratory distress syndrome
نویسندگان
چکیده
A study published in the previous issue of Critical Care demonstrates that measurement of the pulmonary dead-space fraction is superior to hypoxemia as an indicator of a favorable physiologic response to prone positioning in patients with severe acute respiratory distress syndrome. These results add to the growing evidence supporting the clinical and research value of measuring pulmonary dead space in patients with acute respiratory distress syndrome and using this pulmonary physiologic end-point as one indicator of a favorable response to therapy.

What do dead-space measurements tell us about the lung with acute respiratory distress syndrome?
In this issue of RESPIRATORY CARE, Kallet et al1 describe the prognostic value of sequential dead-space measurements in patients with acute respiratory distress syndrome (ARDS). The simple calculation using arterial and mixed expired partial pressures of carbon dioxide (the Enghoff modification of the Bohr dead-space equation: physiologic dead-space volume divided by tidal volume [VD/VT]) is mo...

BACKGROUND Little is known about the alveolar dead-space fraction after the first week of acute respiratory distress syndrome (ARDS). We measured the dead-space fraction in the early phase (first week) and the intermediate phase (second week) of ARDS, and evaluated the association of dead-space fraction with mortality. METHODS We prospectively measured dead-space fraction and other variables ...

BACKGROUND The ratio of pulmonary dead space to tidal volume (VD/VT) in acute respiratory distress syndrome (ARDS) is reported to be between 0.35 and 0.55. However, VD/VT has seldom been measured with consideration to the evolving pathophysiology of ARDS. METHODS We made serial VD/VT measurements with 59 patients who required mechanical ventilation for > or = 6 days. We measured VD/VT within ...

Dead space is an important component of ventilation-perfusion abnormalities. Measurement of dead space has diagnostic, prognostic and therapeutic applications. In the intensive care unit (ICU) dead space measurement can be used to guide therapy for patients with acute respiratory distress syndrome (ARDS); in the emergency department it can guide thrombolytic therapy for pulmonary embolism; in p...

Introduction:Guillain-Barre Syndrome(GBS) is the most common cause of acute flaccid paralysis. Respiratory failure is the most serious short-term complication of GBS and invasive mechanical ventilation is required in 30% of patients.moreover,60% of those who are intubated develop major complications including pnemonia,sepsis,GI bleeding and pulmonary embolism. Thus respiratory failure predictio...
