INPUT ARTICLE: Article: When meeting someone for the first time, a casual handshake is appropriate. However, if you're meeting a closer friend or relative, French people usually offer a small peck on the cheek as a form of greeting. Follow these rules when greeting people in France. If you're trying to give off a French vibe at home, try greeting friends and family members with a kiss like they do in France. Stick to people you're close with, however, as people from non-French cultures may be startled by a cheek kiss. In France, conversation usually revolves around art, culture, and politics. Read local magazines, local news, as well as international news. This way, you'll have something to talk about that makes you seem more French. To make it easier to keep up with the news, download an app on your phone that lets you read the headlines during downtime during the day. Don't hesitate to bring up your favorite books and works of art. This will make you seem considerably more French. Avoid topics like gossip, especially celebrity gossip, as it's seen as largely uninteresting in France. Small talk is not a huge part of French culture, but it's occasionally considered appropriate. If someone is making eye contact with you while you're eating alone, don't hesitate to strike up a conversation. During train delays, it's not uncommon for French people to commiserate with one another by casually complaining about the train. Make conversation about typically French topics. For example, ask if a stranger has seen a recent play or art show. Mention a recent story in the paper. Personal space is a pretty big issue in France. Avoid touching or bumping into people unnecessarily and try to keep your hands to yourself as much as possible when riding on crowded trains. This rule is especially important if you're actually in France as opposed to trying to look French at home.

SUMMARY: Greet people like you're French. Converse about culture and politics. Make small talk at cafes and on trains. Respect people's personal space.

INPUT ARTICLE: Article: If a pulmonary embolism is confirmed as the cause of obstructive shock, it is key to have this treated as soon as possible. Sometimes a "thrombolytic" (clot-busting) drug can be considered to treat a large pulmonary embolism. However, in cases of severe shock, surgery or a catheter removal is usually the fastest and most effective way to remove the PE and thus relieve the obstruction. If a tension pneumothorax is responsible for the onset of obstructive shock, insert a needle in the affected area for decompression. This procedure is called a "needle decompression." Following insertion of the needle, treatment of the pneumothorax, and stabilization of shock symptoms, you will get a chest tube for ongoing management to prevent any recurrence of the tension pneumothorax. This procedure also involves using a needle. However, in this case, the needle is used to remove fluid from the pericardial sac. Removal of the fluid (normally blood) from the pericardial sac in turn relieves the pressure on the heart, and removes the obstruction that was the underlying cause of shock. Of course, it is key to determine what caused the cardiac tamponade in order to have complete and lasting resolution of shock. The needle pericardiocentesis can be done repeatedly, if necessary, to alleviate pressure on the heart until the underlying cause is resolved. In other cases, a surgical procedure known as a pericardial window is done to relieve the accumulation of the fluid. If constrictive pericarditis (or a related condition) is responsible for obstructive shock, it is key to determine what is causing compression and tightening of the heart sac (called the "pericardium"). If this is unable to be resolved and treated promptly, the heart sac (pericardium) may need to be cut open surgically to relieve pressure on the heart, and to resolve the symptoms of obstructive shock. An intra-aortic balloon pump (IABP) can be used to help open the aortic valve. This, in turn, will allow blood to exit the heart and to more effectively supply the body's vital organs. The IABP intervention has been shown to relieve symptoms of obstructive shock when aortic stenosis is diagnosed as the underlying etiology (cause). The aortic valve should be evaluated, and replaced if it meets the criteria.

SUMMARY:
Remove the clot from a massive PE (pulmonary embolism). Use needle decompression and a chest tube to treat a tension pneumothorax. Opt for pericardiocentesis to treat a cardiac tamponade. Treat the underlying cause of constrictive pericarditis as needed. Treat severe aortic stenosis if this is the underlying cause of shock.
