“…29 However, etCO 2 is dependent on effective minute ventilation and is also influenced by the administration of vasoactive drugs. 30,31 Interestingly, in a recent conference abstract Engel et al showed that the initial, the overall, the last five-minutes and the final value of rSO 2 correlated better with ROSC than the respective values of etCO 2 . 32 The etCO 2 has been also used as a tool for evaluation of the efficacy of chest compressions, and in this regards also rSO 2 is currently investigated for its correlation with the efficacy of resuscitation.…”

“…One animal and one human study showed that high doses of adrenaline (>1 mg) cause pulmonary ventilation/perfusion defects due to pulmonary blood flow redistribution, decreasing ETCO 2 [52,77]. In another study, adrenaline increased CPP and myocardial blood flow, but decreased cardiac output [39].…”

“…Ward et al compared the use of mechanical and manual chest compressions during cardiac arrest based on continuous monitoring of ETCO 2 and reported that cardiac output produced with mechanical chest compressions is increased compared to manual compressions [24]. However, it should be noted that many potential confounding factors may affect the levels of expired end-tidal ETCO 2 during cardiac arrest, such as the cause of the arrest, the initial heart rhythm, the early onset of CPR, the rescuer fatigue, and the administration of drugs [28,[36][37][38][39]. Of note, when vasopressors are injected, the ETCO 2 concentration may decrease, concomitant with an increase in coronary perfusion pressure [11,39].…”

“…However, survival was superior with adrenaline than with controls. Lindberg et al [37], in 18 pigs with VF after sternotomy and closure, showed that while adrenaline (or noradrenaline) increased CPP during the arrest up to 45 mmHg compared to only 7 mmHg for controls, it significantly impaired cardiac output and oxygen delivery after successful resuscitation. Chen et al [38], in 47 rabbits with arrest after ET tube clamping, found that adrenaline increased CPP from 4 to 38 mmHg whereas vasopressin failed to do this.…”
