Introduction
Each breath during CPR typically lasts 1 to 1.5 seconds. When performing CPR, it is important to observe and assess whether resuscitation is successful. Signs of successful CPR include palpable pulses in major arteries, gradually rising blood pressure, presence of pupillary reflexes, and improvement in skin color and complexion. If any discomfort occurs, medical attention should be sought promptly.
During cardiopulmonary resuscitation (CPR), each breath typically lasts about 1–1.5 seconds. Specific details are as follows:
CPR mainly includes chest compressions and rescue breathing. The specific steps are: lay the patient flat on a firm, level surface, clear any vomit, and ensure the airway is open. Then perform chest compressions over the heart and sternum area, followed by rescue breathing. Each breath should last 1–1.5 seconds with a volume of approximately 1000 mL. Each breath should be delivered for at least one second to ensure adequate ventilation. While delivering breaths, observe the patient’s chest—breathing should stop once visible chest rise occurs. The recommended compression rate is 100–120 per minute, following a ratio of 30 compressions to 2 breaths, resulting in approximately 6–8 breaths per minute.
During CPR, it's important to monitor and assess signs of successful resuscitation. If a pulse is detectable in the major arteries, blood pressure gradually rises, pupillary light reflex returns, and skin color and overall appearance improve, these indicate that CPR has been successful. If any discomfort or complications occur, prompt medical attention and treatment are necessary.
