Table 2 Comparison of cardiopulmonary resuscitation quality metrics and intubation time among the three cardiopulmonary resuscitation-intubation sequences by the type of airway during cardiopulmonary resuscitation

From: Compromised cardiopulmonary resuscitation quality due to regurgitation during endotracheal intubation: a randomised crossover manikin simulation study

  Oropharyngeal regurgitation Clean airway
Variables P Post-hoc P Post-hoc
CCF 0.471 NA 0.848 NA
Compression depth 0.746 NA 0.059 NA
Compression rate 0.587 NA 0.722 NA
The longest interruption 0.033 1 < 3a 0.178 NA
Intubation time 0.005 1 < 3b, 2 < 3c 0.305 NA
  1. Abbreviation: CCF chest compression fraction, NA not applicable, 1, 2, 3 the first, second, and third CPR-intubation sequence
  2. a The longest interruption in the first vs. third CPR-intubation sequence, P = 0.010
  3. b Intubation time in the first vs. third CPR-intubation sequence, P = 0.002
  4. c Intubation time in the second vs. third CPR-intubation sequence, P = 0.012
