Steady-state end-tidal alveolar dead space fraction and D-dimer: bedside tests to exclude pulmonary embolism.
STUDY OBJECTIVE Less than 35% of patients suspected of having pulmonary embolism (PE) actually have PE. Safe bedside methods to exclude PE could save health-care resources and improve access to diagnostic testing for suspected PE. In patients with suspected PE, we sought to determine the sensitivity, specificity, and negative predictive value of (1) a steady-state end-tidal alveolar dead space ...
متن کاملThe Diagnostic Value of End-tidal Carbon Dioxide (EtCO2) and Alveolar Dead Space (AVDS) in Patients with Suspected Pulmonary Thrombo-embolism (PTE)
Introduction: Capnography, is an easy, fast and practical method which its application in the diagnosis of Pulmonary Thromboendarterectomy (PTE) has recently been studied. This study aimed to assess the diagnostic value of end-tidal CO2 (ETCO2) and the alveolar dead space (AVDS) in the diagnosis of patients suspected to PTE who have been referred to the emergency department. Materials and Metho...
متن کاملThe impact of the introduction of a rapid D-dimer assay on the diagnostic evaluation of suspected pulmonary embolism.
BACKGROUND Rapid D-dimer assays are being used in the diagnostic evaluation of suspected pulmonary embolism (PE). Although this hypothesis is anticipated to decrease the use of ventilation-perfusion (VQ) scans and other diagnostic tests for PE, it has not been tested in a "real-world" environment. SUBJECTS AND METHODS A randomized prospective trial was conducted on 470 of the 5390 enrolled pa...
متن کاملD-dimer for the exclusion of acute venous thrombosis and pulmonary embolism: a systematic review.
BACKGROUND Despite extensive literature, the diagnostic role of d-dimer for deep venous thrombosis (DVT) or pulmonary embolism (PE) remains unclear, reflecting multiple d-dimer assays and concerns about differing sensitivities and variability. PURPOSE To systematically review trials that assessed sensitivity, specificity, likelihood ratios, and variability among d-dimer assays. DATA SOURCES...
