Table 3 Comparison of intrapleural pressure between CCT-CPR and UCT-CPR

From: Presence of chest tubes does not affect the hemodynamic efficacy of standard cardiopulmonary resuscitation

Parameter CCT-CPR for 1st 3 min (n = 10) UCT-CPR for 1st 3 min (n = 10) p value CCT-CPR for 2nd 3 min (n = 10) UCT-CPR for 2nd 3 min (n = 10) p value
IPP max. (mmHg) 17 ± 22 12 ± 11 0.586 16 ± 23 10 ± 13 0.531
IPP min. (mmHg) − 9 ± 6 − 6 ± 5 0.141 − 8 ± 6 − 13 ± 7 0.857
