mng tension ptx in unstable pt
needle thoracostomy
coronary artery territories and ecg leads
S - v1, v2 -> LAD
A - V3, V4 -> LAD
L - I, AVL, V5, V6 -> LAD or left circumflex
I -II, III, avF -> right coronary -> posteromedial papillary mucle and inf wall of left ventricle
LAD–> anterolateral papillary msucle and anterior wall
papillary muslce rupture secondary to MI presents as:
APO secondary to MR
Which papillary muscle is more susceptible to rupture and why
posteromedial muslce because single blood suply
the anterolateral one is not as susceptible to ruputre as it has a dual blood supply
timeline of MI cx
tx of low - moderate hospital acquired pneumonia
PO amoxicillin and clavulanate
tx of moderate community aquired pneumonia
IV benzylpenicillin and PO doxycylcine
tx of aspiration pnemonia
PO metronidazole
TX of high severity HAP or high risk MDR organisms

first line mng of SVT
Vagal manuvers- valsalva, carotid sinus massage, facial immersion in cold water
mng of hemodynamically unstable atrial flutter
synchronised electrical cardioversion
when is IV adenosine used in the context of atrial flutter
Reveal underlying flutter waves by causing transient AV block
Not a treatment
