Passive leg raising during CPR

Measuring end-tidal carbon dioxide (ET CO2 ) is a practical non-invasive method for detecting pulmonary blood flow, reflecting cardiac output and thereby the quality of CPR. It has also been shown to rise before clinically detectable return of spontaneous circulation … Continue reading

Fetal monitoring during EMS transport

Can cardiotocography be applied in the pre-hospital setting? French physicians assessed its feasibility in 145 patients enrolled during 119 interhospital transfers and 26 primary prehospital missions. Their physician-staffed ambulance teams included 19 emergency physicians and one anaesthetist. Interpretable tracings were … Continue reading

ETCO2 and ROSC

One for the ‘hardly surprising’ category…. A study of end-tidal CO2 during out-of-hospital adult and child cardiac arrest resuscitation showed a sudden rise in CO2 was associated with return of spontaneous circulation (ROSC), suggesting that witnessing this would be a … Continue reading

Tracheal tube cuff pressure in flight

Tracheal tube cuff pressures increased from a mean 28.7 cm H2O pre-flight to 62.6 cm H2O in flight (mean altitude increase 2260 feet) in a Swiss helicopter-based study. At cruising altitude, 98% of patients had intracuff pressure >30 cm H2O, 72% had … Continue reading
