Loss Of Oxygen During Cardiac Arrest
When someone goes in 2 complete cardiac arrest. No pulse heaetbeat. How many min would it take without oxyegen to b brain dead?
Survival from cardiac arrest is determined by many things, and time is certainly an important one.
However, how well the body is oxygenated and perfused during the arrest (say, by cpr) as well as body temperature all play a role. In your question, you imply there is no oxygen - so the answer is mere minutes. ...Read more
Many options: Asystole, ventricular fibrillation, ventricular tachycardia, torsades DES pointes, . The ventricles fail to provide significant arterial flow to the aorta and the pulmonary artery, the systemic arterial pressure drops below critical level leading to cerebral hypoperffusion and syncope. If prolongued brain death occurs within 5 minutes at normothermia. ...Read more

Sometimes people: Have a cardiac arrest preceded by an arrhythmia, or abnormal heart rhythm. Not always from a blockage of a coronary artery. The rhythm that may respond to coughing is called ventricular tachycardia. If th epatient coughs hard, it may sometimes trigger the neves to the heart that slow the heart rate and at least temporarily return the rhythm to one that is less dangerous. But you must seek help. ...Read more
Doctors arresting?: If I had an intraoperative arrest I would hope the anesthetist and surgeon would do chest compressions, bag valve mask me, and treat the cause of the arrest. Physicians have many opinions on how they want to be treated themselves. ...Read more
Immediately: Cardiac arrest means that the heart has stopped beating. ...Read more
Can an electrocardiogram prevent sudden cardiac arrest in young teenagers/adults who die during marathons?
Screen test: ECG is used because it is relatively inexpensive. We have no good cost effective screening test. Cardiac arrest is rare when compared to the numbers of exercising population. Tests become more effective when a specific question within the effectiveness of the test are the reason for the test. ...Read more
What does "pulmonary embolectomy with cardiac arrest and ROSC", mean? They did use CPB during procedure
Here is the breakdown.
There was a blood clot in the lungs that was removed surgically. During the procedure, the heart stopped. With CPR, the heart restarted and starting pumping normally (ROSC = return on spontaneous circulation). The use of CPB (cardiopulmonary bypass) is not indicated in a situation like this. Hope this helped. ...Read more
Vasovagal attack during surgery caused cardiac arrest. Doctors want to attempt another laparoscopic to remove gallbladder? Chances of arrest again?
Unlikely: Anesthesiologist will give meds to keep heart from going too slow next time ...Read more
Happens everyday!: It's standard operating procedure in many heart operations for the surgeon to stop or arrest the heart and put the patient temporarily on a heart-lung machine. In fact, if one should suffer an unexpected cardiac arrest, the heart operating room is the very best place in the world for it to happen (since the resuscitation statistics there are stellar.). ...Read more
I read adrenaline can cause sudden cardiac arrest during physical activity. How do you know if your workout is safe? And, can emotional stress cause sudden cardiac arrest? I struggle with anxiety and am worried about this.
Don't worry: Sudden cardiac arrest during exercise and physical activity is almost always due to a congenital (from birth) electrical problem in the heart. If you are concerned, your doctor can run a simple ECG to identify whether you are at risk. ...Read more
In 65 y/o female with asthma and previous cardiac arrest W/ROSC during Pulm. Embolectomy W/ CPB. Which is safest method for pericardial window?
Complicated question: You ask a VERY complicated question about a complex medical history. The 1st thing to ascertain: "why do you need a pericardial window? " Normally, they are for recurrent cardiac effusions; despite the dramatic surgery & event, effusions aren't typical after cardiac arrest. 2nd, need to know why pulm embolism developed. TTYD or use HealthTap Prime to find answers/specialists. Not enough space here. ...Read more
Not common: Unfortunately, uncommon. Hard to say exactly, & depends somewhat on what kind of cardiac arrest, what other problems the person has, how long before care, etc. Generally though, for out-of-hospital arrests, less than 20% survive long enough to be discharged from the hospital. Also concerning is how often cardiac arrest is the 1st sign of underlying CAD (plaque in vessels). See a proactive doctor! ...Read more
Arrest requires CPR: Myocardial infarction (mi) occurs when there is an obstruction of a blood vessel that supplies part of the heart and this leads to damage to the heart muscle. Mi might lead to death and can cause cardiac arrest if not treated but not always. Cardiac arrest means that the heart is no longer pumping blood, can be caused by a variety of things and always leads to death if not treated promptly. ...Read more
Survival rate: Of people that receive initial emergency treatment by ambulance is less than 5%, with 15% returning to spontaneous circulation. With defibrillation within 3-5mins the survival can increase to 30%. Survival depend on the cause of the arrest, circumstances, age. Every minute without oxygen to the organs, specially the brain, decrease the recovery without permanent damage. ...Read more
MI and cardioarrest: A myocardial infarction is an event caused by a blockage in an artery which damages the heart muscle. A cardiac arrest is an event that may be caused by a myocardial infarction or may be caused by other events such as respiratory failure or electrolyte abnormalities which causes the heart to go into an unstable rhythm. In this rhythm the heart cannot pump effectively, so treat the cause. ...Read more
Long list: Sudden cardiac death had several causes: Coronary disease or heart attack may cause sudden cardiac death, but also sudden death can occur in patients with cardiac abnormality of the heart muscle that can be detected on echo cardiogram and sometime undetected on cardiac echo, electrical genetic anomaly may cause sudden death ...Read more
