Misc FP-C Flashcards
MCI
More patients than resouces
Do the most good for the most people
When given priority questions
start with the first category that you aren’t given info about
Shock Index
HR/SBP – 0.8 or higher indicated high likelihood of peri-intubation problems
Indication for surgical airway
Cant intubate cant ventilate
Contraindicaitons for extraglottic airway
Obstruction, Intact Gag Reflex, Esophageal Disease]
Test for varices
Hepatic jugular reflex – Lay flat, elevate legs, press on RUQ and look for JVD. Sign of portal hypertension and therefore esophageal varices
Troubleshooting suction
Work from the machine back to the patient
Anion Gap
<12
Na+K)-(HCO3+Cl
Name for alveolar capillary junction
alveolar capillary membrane
Relationship between Ph and PCO2
For every change of 10 pCO2, pH will change by 0.08 in the OPPOSITE DIRECTION
Minute ventilation
6-8L/min or
Nonintubated: 60ml/Kg/min
Intubated: 120ml/Kg/min
Very Acidotic: 240ml/Kg/min
Mean airway pressure
pPlat
Mean Airway Pressure 10-20 Plateau Pressure (pPlat) always <30
DOPES Equipment Failure
Work from pt to vent
Benzo overdose questions
Flumazenil is generally a bad idea
Coronary Perfusion
Closes coronary ostia during systole. Back pressure during closure perfuses coronary arteries.
HEART IS PERFUSED DURING DIASTOLE
Types of hypoxia
Hypemic and Histotoxic will not become cyanotic
Hypoxic (Gas exchange) – Get rid of obstructions or add pressure
Hypemic/Anemic (Hypovolemic or anemic)
Stagnant (Shock states other than hypovolemia)
Changes in altitude and G forces
Histotoxic (Cyanide, CO, etc)
Types of airway obstruction
Complete (CICO)
Obstruction w/ good air exchange (Stridor)
Partial w/ poor air exchange (Stridor, increased WOB, low SPO2)
Vent question w/ pancreatitis
ARDS
Cardiac question re pressors
Look for best measured amount and best physiological effect
Angina
Stable: CP relieved with rest or up to 3 NTG
Unstable: Chest pain unrelieved w/ 3 NTG or rest
NSTEMI: Unstable angina w/ cardiac markers or ischemic changes
Inferior STEMI question
No choice given for inferior, select posterior
