Letter to the editor in response to "Agreement between continuous and intermittent pulmonary artery thermodilution for cardiac output measurement in perioperative and intensive care medicine: a systematic review and meta-analysis"

[...]the authors state that “continuous” should actually be “semi-continuous” and that there is a delay up to several minutes. For automated semi-continuous pulmonary artery thermodilution a filament attached to the catheter heats up the blood in a random sequence (in contrast to cold fluid boluses used for intermittent pulmonary artery thermodilution) [6, 7].
