- Glomerulus
- Glomerular capsule
- Proximal convoluted tubule
- Nephron Loop
- Descending/ascending loop (loop of henle)

hyper resonance on percussion
Pulsus paradoxus
Pacemaker sites
SA node 60-100
AV node 40-60
Purkinji fibers 20-40
Unstable criteria
Altered LOC or ABC's Hypotension Shock Pulmonary edema Chest pain Respiratory distress
Load and Go criteria
Altered LOC
comprimised ABC’s
Major trauma
Undiagnosed abdo
Pelvic instability
Bilateral femur fracture
Depolarization
- Rapid influx of sodium
- Calcium influx through voltage gated slow Ca2+ channelsb
- K+ outflow when some K+ channels open
Repolarization
Closing of Ca2+ channels
K+ outflow when additional K+ channels open
Procainamide End points
Max dose 17mg/kg
Arrythmia supressed
Hypotension
QRS prolongation >50%
H’s and T’s
Hypothermia Hypoxia H+ Hypovolemia Hyper/hypokalemia Tension pneumo Toxic Tamponade Thrombus coronary Thrombus pulmonary
Dopamine dosages and effects
-2-5mcg/kg/min - mesenteric
5-10 mcg/kg/min – acts primarily on B1
10-20 mcg/kg/min – acts predominantly on A
Describe the treatment for unstable Vs.
Unstable SVT
- Synchronized cardioversion at 50-100J
- consider sedation
stable SVT
- Maintain airway
- O2
- Cardiac monitor to identify/confirm rhythm
- Vital Signs
- Vagal maneuvers
- Adenosine 6mg RIVP followed by 12mg RIVP
- Calcium channel blocker
- beta blocker
Zone of Infarction, Injury, and Ischemia
Ischemia – ST depression, T-wave abnormalities
Injury – ST elevation
Infarction – pathological Q-waves
3 tests to Dx tuberculosis
Chest x-ray
Blood test
Mantoux test
lymph bi op
Sound during percussion
Resonance
Dullness
Hypersonance – tympany
Respiratory acidosis vs alkalosis Acidosis -Hypoventilation inadequate CO2 retention -Airway obstruction -Cardiopulmonary disease -Over sedation -Brain stem injury -pH decreased -HCO3 increased -PCO2 increased
Alkalosis
- Pulmonary hyperventilation causing excessive release of CO2
- Psychoneurosis
- Hypoxemia
- Fever
- pH Increase
- HCO3 decreased
- PCO2 decreased
