Patients in general wards often deteriorate for several hours or even days before a cardiac arrest occurs. [ 64 ] [ 78 ] This has been attributed to a lack of knowledge and skill amongst ward-based staff, in particular, a failure to measure the respiratory rate , which is often the major predictor of a deterioration [ 64 ] and can often change ...
Clinical death is the medical term for cessation of blood circulation and breathing, the two criteria necessary to sustain the lives of human beings and of many other organisms. [1] It occurs when the heart stops beating in a regular rhythm, a condition called cardiac arrest. The term is also sometimes used in resuscitation research.
Patients with cardiac arrests due to problems with the heart were more likely to experience agonal respirations compared to cardiac arrests from a different cause. Patients with agonal respirations due to cardiac arrest are more likely to be discharged home from a hospital alive compared to those who do not experience agonal respirations during ...
In 2016, Em James Arnold, a parent in New York City, had a cardiac arrest and was revived. Arnold’s girlfriend started CPR, but the resuscitation lasted 90 minutes and required nine ...
Patients have died not long after their circulation has returned. One study showed that those who had had an out-of-hospital cardiac arrest and had achieved return of spontaneous circulation, 38% of those people had a cardiac re-arrest before arriving at the hospital with an average time of 3 minutes to re-arrest.

According to the American Heart Association, out-of-hospital cardiac arrest can affect more than 300,000 people in the United States each year. [5] Three minutes after the onset of cardiac arrest, a lack of blood flow starts to damage the brain, and 10 minutes after, the chances of survival are low. [6]
If respiratory arrest remains without any treatment, cardiac arrest will occur within minutes of hypoxemia, hypercapnia or both. At this point, patients will be unconscious or about to become unconscious. [3] Signs and symptoms of respiratory compromise can differ with each patient.
Before cardiac arrest, the body is in a state of homeostasis. Arterial blood circulates appropriately through the body, supplying oxygen to tissues while the venous blood collects metabolic waste products to be utilized elsewhere and/or eliminated from the body. However, during cardiac arrest, the body is in circulatory and pulmonary arrest ...
