Early CPR has been shown to be predictive of survival to hospital discharge,5-7 and minimizing time between compressions and defibrillation was shown to increase the likelihood of shock success for VF/VT arrests.8,9 Studies such as these demonstrate the importance of early, high-quality, uninterrupted chest compressions, whereas other cardiac arrest therapies such as advanced airways and certain medications have not been proven to increase survival rates.10-16 Further research has demonstrated that providers often take too long to check for a pulse17,18 and that pausing for a pulse check after a defibrillation may decrease myocardial perfusion during the critical postdefibrillation period.4
In place of manual pulse checks, the ACLS guidelines propose using physiologic measurements to identify ROSC, such as central venous oxygen saturation (SCVO2) or end-tidal CO2 (PETCO2).

We defined patients who had no histories of AF and no documented AF on continuous electrocardiographic monitoring during hospitalization as the sinus rhythm group, patients who had histories of AF before admission and/or continuously documented AF on continuous electrocardiographic monitoring during hospitalization as having chronic AF, and patients who had AF at admission and recovered to normal sinus rhythm during hospitalization and/or showed sinus rhythm at admission and documented transient AF on continuous electrocardiographic monitoring during hospitalization as having paroxysmal AF.```

Sample text:```Similarly, in a study on 60 subjects, blinks were measured at the beginning and end of a working day (Caffier et al., 2003). Although no significant difference between alert and drowsy phases was found, a slightly decreased blink rate during drowsy phase was reported. However, these results contradict the findings of Morris and Miller (1996) about the efficiency of F in a moving base-flight simulator with 10 sleep-deprived pilots.```
