They ingest bacteria, foreign cells, and damaged and dead cells. (The process of a cell ingesting a microorganism, another cell, or cell fragments is called phagocytosis, and cells that ingest are called phagocytes.). Macrophages secrete substances that attract other white blood cells to the site of the infection.ytokines are the messengers of the immune system. White blood cells and certain other cells of the immune system produce cytokines when an antigen is detected. There are many different cytokines, which affect different parts of the immune system: Some cytokines stimulate activity.
CPR for Infants (up to 12 months of age) CPR for infants is similar to CPR for adults and children. Checking for responsiveness: never shake an infant as this may cause brain damage. To check for responsiveness in an infant, tap the soles of the feet while calling to the infant in a loud voice.
In a 2010 prospective study of cardiac arrest in children (age 1â17) for arrests with a non-cardiac cause, provision by bystanders of conventional CPR with rescue breathing yielded a favorable neurological outcome at one month more often than did compression-only CPR (OR 5.54; 95% confidence interval 2.52â16.99).
