your partner is observing the scene for danger. this is called the <u>Contact and cover</u> approach
When two patrol policemen come across a potential suspect, they adopt the contact and cover strategy. The contact officer speaks with the person, records the conversation, checks for warrants, etc. The entire transaction is handled by the contact officer. In comparison to the interview subject, the cover officer is in a better position. The cover cop stays out of the mundane parts of the conversation. Scene safety for the contact officer is the exclusive duty of the cover officer. When a threat materializes, like as when the subject starts to reach for a concealed weapon, etc., the cover officer simply steps in to stop it.

A continual "lub-dub, lub-dub" is a common way to characterize the sounds. The mitral valve and tricuspid valve closing is the source of the first "lub-dub." Following the first "lub-dub," the second "lub-dub" is made by the aortic and pulmonary valves shutting.
A blood backflow brought on by the heart's mitral valve failing to seal securely. When the mitral valve of the heart fails not close completely, blood can flow backward inside the heart, a condition known as mitral valve regurgitation. Breathing difficulties, weariness, dizziness, and an erratic, fluttering heartbeat are all symptoms. Treatment might not be necessary for everyone. Between the heart's two right chambers is where the tricuspid valve is located. There are three little flaps of tissue that make up the tricuspid valve (called cusps, or leaflets). These valve flaps open to let blood to flow from the right atrium, which is the upper chamber, to the right chamber, which is the lower chamber (right ventricle).
