Bedside end tidal CO2 as a screening tool to exclude pulmonary embolism

The 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...

End-tidal CO2 for exclusion of suspected pulmonary embolism: a new partner for Wells?

The diagnosis of PE remains a challenge because of highly variable clinical symptoms. Consequently, the diagnosis of PE has been finally confirmed in ,35% of patients with a clinical suspicion of PE [3]. A simple bedside test with the ability to exclude PE in patients who do not have it, while not overlooking true-positive cases, is desired and will prevent unnecessary exposure to contrast agen...

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 ...

Pulmonary Edema after Catastrophic Carbon Dioxide Embolism during Laparoscopic Ovarian Cystectomy

Laparoscopy is a surgical procedure used both for diagnosis and for various treatments. A rare but sometimes fatal complication of laparoscopy is pulmonary embolism with CO2 resulting in pulmonary edema. During laparoscopic gynecological surgery in a 29-year-old woman who had previously undergone lower abdominal surgery, the end-tidal CO2 suddenly increased from 40 mmHg to 85 mmHg and then decr...
