Resuscitation
-
International neonatal resuscitation guidelines recommend that correct tube placement should be confirmed by clinical assessment and exhaled CO2 detection. Absence of exhaled CO2 after intubation suggests oesophageal intubation, non-aerated lungs, low tidal volume delivery, or low cardiac output. The relationship between changes in cardiac output and exhaled CO2 in neonates is unknown. The aim of the study was to determine if changes in cardiac output affect exhaled carbon dioxide in a porcine model of neonatal resuscitation. ⋯ A significant decrease in cardiac output was not associated with changes in exhaled CO2 or failure to achieve a Pedi-Cap(®) colour change.

100% reliability does not exist in diagnostics; SSEP in postanoxic coma.
