ORs. I want two rooms in about three minutes.
Hi, how you doing? My names Dr. Luthan.
Im the doctor in charge.
Youve been shot but youre doing fine. Mind if I look?
Lets take a little look.
Its not so bad. Do me a favor. Take a deep breath when I say, "Now".
Jodie in Trauma. Weve got two patients with gunshots. We need two ORs.
Deep breath.
Great. No breath sounds on the right. Get a chest tube..
proteins, but there are (as of July 2011) no known structures of any OR. There is a highly conserved sequence in roughly three quarters of all ORs that is a tripodal metal ion binding site, and Suslick has proposed that the ORs are in fact metalloproteins (mostly likely with zinc, copper and possibly manganese ions) that serve as a Lewis Acid site for binding of many odorant molecules.
ORS파에 묻혀서 보이지 않음
· QRS파 넓어짐(0.12초 이상)
· 빠르게 반복하여 심실 수축
· 리듬 : 규칙적
· 심실근육세포가 빠르고 불규칙하게
흥분→ 비효과적 수축 및 심박출 못함
EKG 특징
· 파형을 구분할 수 없음
· 극도로 불규칙적이고 모호한 곡선
원인
허혈성 심질환, 심근경색, 저칼륨혈
정상상태
심전도
● 우심방 상부에 있는 동방결절(SA node)에서 60~100회/분의 전기적 자극을 내보냄
심전도계
➀ 동방결절에서 전기적 자극을 내보냄
➁ 자극이 심방을 통과하여 심방 수축이 발생
➂ 방실결절(AV node)에 도달한 뒤 잠깐 지체
➃ His 속을 타고 양쪽 각을 통해 좌우 심실로 내려감
➄ 자
