Answer :
CPR stands for Cardiopulmonary Resuscitation. It is an emergency technique applied when the heart of a patient stops. By applying pressure on the sternum between the line at T4 and T9, the blood within the heart can be manually compressed and pushed into the pulmonary and systemic circuits. Option C.
CPR, standing for Cardiopulmonary Resuscitation, is a life-saving technique used in emergencies when a person's heart stops. It involves applying pressure on the sternum to push blood into the pulmonary and systemic circuits.
Regular recertification in CPR is recommended for medical personnel and the public. This is particularly critical for the brain as lack of blood flow can cause irreversible neuron damage and death within minutes.
CPR involves chest compressions at least 5 cm deep and at a rate of 100 compressions per minute, and is performed until the patient regains spontaneous contraction or is declared dead by an experienced healthcare professional.
Proper training is essential in performing Cardiopulmonary Resuscitation, as untrained application can result in broken ribs, broken sternum or severe patient damage.
Hence, all medical personnel and concerned members of the public are encouraged to get certified in CPR, with recertification held regularly.
In the context of respiration and ventilation, external respiration refers to the exchange of gases between the lungs and the blood, interpulmonary respiration refers to the gas exchange occurring within the lungs.
Internal respiration is the gas exchange between the blood and body cells, and pulmonary ventilation involves the movement of air in and out of the lungs.
Hence, the correct answer is Option C.
