Investigating the Relationship Between End Tidal Carbon Dioxide and Arterial Carbon Dioxide Pressure in Patients With Respiratory Distress Referred to the Emergency Room of Hazrat Rasool Akram Hospital

Authors

Abstract:

Background: Measuring End-Tidal Carbon Dioxide (ETCO-2) can be a non-invasive, fast, and reliable method to predict partial pressure of carbon dioxide (PaCO2) in patients with respiratory distress. This method, which can be a suitable substitute to measure PaCO2, is being used in many emergency rooms and operating rooms in developed countries, but its exact relationship with PaCO2 has not been confirmed yet. This study aims to investigate the relationship between PaCO2 and ETCO2 in patients with respiratory distress referred to the emergency. Materials and Methods: Arterial blood gases were measured in patients referred to the emergency room of Hazrat Rasool Akram (PBUH) Hospital with the main complaint of respiratory distress, and the ETCO2 of the patient was measured simultaneously with a capnograph. At the same time, the blood pressure and body temperature of the patients were also measured. The obtained information was collected in a sheet and statistically analyzed using SPSS software version 15. Results: A total of 120 patients were included in the study whose mean age was 48.3. The mean PaCO2 and ETCO2 were 47.45 and 26.9, respectively. The mean respiratory rate was 37.4 and diastolic (89.9) and systolic (124.9) blood pressure. A total of 48.33% of patients were women. Statistical analysis showed a significant relationship between PaCO2 and ETCO2 (P=0.0001; CC=0.436). Linear regression analysis showed that ETCO2 predicts PaCO2 with R=0.424. Conclusion: A good correlation was found between PaCO2 and ETCO2 and this correlation was higher in diseases such as sepsis and COPD. Variables such as age, sex, and blood pressure did not affect this correlation. Of course, more studies on healthy people are necessary to confirm these findings.

The relationship between end tidal carbon dioxide and arterial carbon dioxide during controlled hypotensive anaesthesia.

OBJECTIVES To prospectively assess the magnitude of changes in the arterial-to-end tidal carbon dioxide gradient [P(a-ET)CO2] as well as in the ratio of physiological dead space to tidal volume (Vdphys/Vt) during controlled hypotensive anaesthesia, and to evaluate whether or not ventilatory requirements remain unaltered during this procedure. SUBJECTS AND METHODS Twelve adult patients with Am...

Concordance between side-stream end-tidal carbon dioxide and arterial carbon dioxide partial pressure in respiratory service setting

Non-invasive monitoring of arterial oxygen using percutaneous pulse oximetry is well established. Although some studies show a good correlation of transcutaneous end-tidal carbon dioxide partial pressure (PetCO2) with arterial carbon dioxide partial pressure (PaCO2), they were performed in research settings and involved restricted populations such as paediatric, accident and emergency, or inten...

Comparison of end-tidal carbon dioxide and arterial blood bicarbonate levels in patients with metabolic acidosis referred to emergency medicine

Introduction: The routine and gold standard method to diagnose of acid - base disturbance is arterial blood gas (ABG) sampling. Capnography could be used to measure the end-tidal carbon dioxide (ETCO2) levels and ETco2 has a close correlation with the PaCo2. The aim of this study was comparison the ETco2 and arterial blood bicarbonate levels in patients with metabolic acidosis. Methods: In a de...
