NURSING ANM AND GNM

Detailed explanation-1: -Time is very important when an unconscious person is not breathing. Permanent brain damage begins after only 4 minutes without oxygen, and death can occur as soon as 4 to 6 minutes later.

Detailed explanation-2: -Cardiac arrest can be fatal if it lasts longer than 8 minutes without CPR. Brain damage can happen after just 5 minutes. Cardiac arrest treatment should start right away, even if you’re not in the hospital.

Detailed explanation-3: -How long can the brain go without oxygen before serious damage occurs? After five to ten minutes of not breathing, you are likely to develop serious and possibly irreversible brain damage. The one exception is when a younger person stops breathing and also becomes very cold at the same time.

Detailed explanation-4: -Most people who experience cardiac arrest do not survive. Among those who do, there is risk of neurologic dysfunction, brain injury, disorders of consciousness, neurocognitive deficits, changes in quality of life, as well as physical and psychological wellbeing.

Detailed explanation-5: -Risk of Brain Damage after Cardiac Arrest If CPR is initiated within: 0–4 minutes: unlikely to develop brain damage. 4–6 minutes: possibility of brain damage. 6–10 minutes: high probability of brain damage.
