[The tendency of changes in blood oxygen saturation and arrhythmia: a clinical report of 500 cases].
To observe the correlation of duration of hypoxia and degree of arrhythmia in patients with and without past history of cardiac disease, in order to provide a warning value supplied by pulse oxygen saturation (SpO2) monitoring for clinical surveillance. ⋯ The hypoxemia (lowering of SpO2) is the independent risk factor leading to arrhythmia. Healthy heart can tolerate hypoxia better, and the SpO2 warning value is ≤0.60. Compared with the non-cardiac disease group, patients in cardiac disease group has significantly lower toleration ability against hypoxia, and its SpO2 warning value is lower than 0.95.

[Effect of ulinastatin on improving inflammatory response and myocardial and lung tissue injury after cardiopulmonary resuscitation in pigs].
To evaluate the effects of ulinastatin (UTI) on improving inflammatory response and myocardial and lung tissue injury after cardiopulmonary resuscitation (CPR) in porcine model. ⋯ UTI can significantly reduce the pro-inflammatory reaction and the extent of myocardial and lung tissue injury after resuscitation.

[The impact of interrupted abdominal aorta compression on resuscitation effects of cardiac arrest rabbit].
To determine whether interrupted abdominal aorta compression-cardiopulmonary resuscitation (IAAC-CPR), as a new cardiopulmonary resuscitation (CPR) method, can improve resuscitation effects on rabbits with cardiac arrest (CA). ⋯ Abdominal aorta compression in the intermittent period of chest compression (IAAC-CPR) increases MAP, CPP and the successful rate of resuscitation, thus improves the outcome.

[Protective effect of anisodamine against myocardial cell apoptosis through mitochondria impairment in cardiac arrest in pigs].
To investigate the protective effect of anisodamine on myocardial mitochondrial damage in cardiac arrest (CA) in pigs. ⋯ By decreasing the protein content of Cyt C, and reducing the extent of damage to myocardial mitochondria, anisodamine can protect the myocardial ultrastructure, and restrain the mitochondria-induced cell apoptosis after resuscitation.

[The influence of hypertensive perfusion on ultrastructure of gastrointestinal tissue and enzymology of pigs after cardiopulmonary resuscitation].
To study ultrastructure of gastrointestinal tissue and enzymology in pigs after cardiopulmonary resuscitation (CPR) in conditions of hypertensive perfusion. ⋯ Gastrointestinal function injury, abnormal energy metabolism, increased serum DAO levels, destruction of intestinal microvilli were found after CPR. Hypertensive perfusion could improve cell energy metabolism, reduce the mucosal injury, and protect the digestive tract from injury due to CPR.
