Final answer:
Nurses trained in CPR focus on manually maintaining blood circulation by applying chest compressions between the T4 and T9 vertebrae on the sternum to resume blood flow, particularly to the brain, following current standards for depth and rate of compressions.
Step-by-step explanation:
Focus of Nurses Trained in Cardiopulmonary Resuscitation (CPR)
The nurse in the hospital who is trained in cardiopulmonary resuscitation (CPR) focuses on applying emergency techniques to maintain blood flow in patients whose hearts have stopped. During CPR, the nurse applies pressure on the sternum, specifically between the T4 and T9 vertebrae, to compress the heart and manually push blood into the systemic and pulmonary circuits. This action is crucial to prevent irreversible brain damage, as neural death can occur within minutes of blood flow loss. CPR is conducted with a compression depth of at least 5 cm, at a rate of 100 compressions per minute, which is comparable to the rhythm of the song "Staying Alive" by the Bee Gees.
Emphasis is on delivering high-quality chest compressions rather than providing artificial respiration. The technique involves correctly positioned hand placement on the sternum to avoid injuries such as broken ribs, sternum, or damage to the liver through the xiphoid process. Adequate training for medical personnel and the public is emphasized for effective CPR execution, with courses widely available for certification.
