End-tidal CO2 in mechanical versus conventional CPR

End-tidal CO2 in mechanical versus conventional CPR

Introduction Out-of-hospital cardiac arrest (OHCA) generally has a poor prognosis. The development and use of a mechanical chest compression device has been suggested as a measure to achieve sufficient and continuous cardiopulmonary resuscitation (CPR). The mechanical chest compression device (Autopulse®) consists of a battery-driven board with a band attached that applies a 20% anteriorposteri...

Utility of Prehospital Quantitative End Tidal CO2?

INTRODUCTION End tidal CO2 (ETCO2) has been established as a standard for confirmation of an airway, but its role is expanding. In certain settings ETCO2 closely approximates the partial pressure of arterial CO2 (PaCO2) and has been described as a tool to optimize a patient's ventilatory status. ETCO2 monitors are increasingly being used by EMS personnel to guide ventilation in the prehospital ...

End-tidal CO2 monitoring during anesthesia.

A novel method of distal end-tidal CO2 capnography in intubated infants: comparison with arterial CO2 and with proximal mainstream end-tidal CO2.

OBJECTIVE The objective of this study was to evaluate a novel method of distal end-tidal CO2 capnography by comparison with PaCO2 and with the more standard method that measures mainstream proximal end-tidal CO2 in intubated infants. METHODS Included in the study were all infants who were ventilated with conventional mechanical ventilation and intubated with a double-lumen endotracheal tube i...

Correlation properties of tidal volume and end-tidal O2 and CO2 concentrations in healthy infants.

We investigated whether breath-to-breath fluctuations in tidal volume (VT) and end-tidal O2 and CO2 exhibit long-range correlations and whether parameters describing the correlations can be used as noninvasive descriptors of control of breathing. We measured VT and end-tidal O2 and CO2 over n = 352 +/- 104 breaths in 26 term, healthy, unsedated infants (mean age +/- SD: 36 +/- 6 days) and calcu...
