Observational StudyConcordance and limits between transcutaneous and arterial carbon dioxide pressure in emergency department patients with acute respiratory failure: a single-center prospective observational study.
Transcutaneous CO₂ (PtCO₂) is a continuous and non-invasive measure recommended by scientific societies in the management of respiratory distress. The objective of this study is to evaluate the correlation between PtCO₂ and blood pressure of CO₂ (PaCOv) by blood gas analysis in emergency patients with dyspnoea and to determine the factors that interfere in this correlation. ⋯ In patients admitted in emergency unit for acute respiratory failure, there is a significant correlation between PaCO₂ and PtCO₂, mainly for values below 60 mm Hg. The two limiting factors of use are hyperthermia and users training.

Observational StudyIncreasing bystander CPR: potential of a one question telecommunicator identification algorithm.
Telecommunicators use a two-question algorithm to identify cardiac arrest: Is the individual conscious? Is the individual breathing normally? Although this approach increases arrest identification and consequently bystander CPR, the strategy does not identify all arrests and requires time to complete. We evaluated the implications of a one-question strategy that inquired only about consciousness. ⋯ A single-question arrest identification algorithm may not achieve a favorable balance of risk and benefit.
