The right answer is B. Begin chest compressions.
Chest compression is a first aid gesture that occurs under two circumstances:
** the victim is conscious and chokes (total obstruction of the upper airways) but can not practice Heimlich's method (example of a pregnant woman or an obese person, or an infant on which the method Mofenson failed, or an unconscious victim for whom the insufflations do not pass); the purpose here is to cause an overpressure in the lungs to dislodge the foreign body;
** the victim is unconscious, does not breathe and his heart is no longer beating, the chest compressions are used here to circulate the blood; alternating thirty chest compressions and two breaths (mouth-to-mouth); all artificial ventilation / cardiac massage is called cardiopulmonary resuscitation (CPR).
One important concept to know that was not mentioned in the question or in the propositions is that there has to be a cardiopulmonary arrest to start the chest compression because there is we may have an unconscious victim who does not respond but breathes!
right side:
Blood enters the heart through two large veins, the inferior and superior vena cava emptying oxygen-poor blood from the body to the right atrium.
atrium contracts, blood flows from your right atrium into your <em>right ventricle</em> through the open tricuspid valve.
ventricle contracts, blood leaves the heart through the pulmonic valve, into the <em>pulmonary artery</em> and to the lungs where it is oxygenated.
left side:
<em>pulmonary vein</em> empties oxygen-rich blood from the lungs into the <em>left atrium</em>.
contracts, blood flows from your left atrium into your <em>left ventricle </em>
ventricle contracts, blood leaves the heart through the aortic valve, into the<em> aorta </em>and to the body.
veins carry blood to the heart ( deoygenated blood)
Arteries carry blood from heart ( oxygen rich blood)
Capillaries connects them.
