959-102 What “Dose” of Oxygen is Required in Treating Prolonged Cardiac Arrest

The Aassociation between Pre-Cardiac Arrest Comorbidity and Unsuccessful Cardiopulmonary Resuscitation in Patients with Cardiac Arrest

Background and Objective: Patients suffering from cardiac arrest (CA) have poor prognosis and survival. The association of pre-arrest comorbidity with unsuccessful resuscitation in patients with CA is far from clear. The aim of the present study was to investigate the association between pre-existing comorbidity and unsuccessful resuscitation following CA in Iranian patients. Materials and Met...

Less oxygen for cardiac arrest patients is better

There is no doubt that oxygen is necessary to sustain life. We have been using oxygen since the late 19th century with its use taken for granted. However, administering oxygen above atmospheric concentration should be prescribed as a medication accounting for potential adverse effects. Exposure to high dose of supplemental oxygen has been associated with pulmonary and cardiac toxicity. Moreover...

How much oxygen in adult cardiac arrest?

Although experimental studies have suggested that a high arterial oxygen pressure (PaO2) might aggravate post-anoxic brain injury, clinical studies in patients resuscitated from cardiac arrest (CA) have given conflicting results. Some studies found that a PaO2 of more than 300 mm Hg (hyperoxemia) was an independent predictor of poor outcome, but others reported no association between blood oxyg...

Hyperoxia toxicity after cardiac arrest: What is the evidence?

This review gives an overview of current knowledge on hyperoxia pathophysiology and examines experimental and human evidence of hyperoxia effects after cardiac arrest. Oxygen plays a pivotal role in critical care management as a lifesaving therapy through the compensation of the imbalance between oxygen requirements and supply. However, growing evidence sustains the hypothesis of reactive oxyge...
