Summary:
- The death rattle is a sign that a person is approaching the end of his life. A person usually lives for 23 hours after the death rattle begins.
-This occurs because as consciousness decreases, patients lose their ability to swallow and clear oral secretions. Air moves over these pooled secretions resulting in noisy breathing.
- It is important to know that this is not distressing for the patient because they are non-responsive and deeply asleep at this point.
