respiratory Flashcards
rapid shallow breathing index
105 cut off Resp rate/Vt liters, e.g., rate 32/0.3L=106 too high
ECMO
VV-PaO2 determined by volume of blood through ECMO oxygenator relative to through pulm circulation–increase flow to increase PaO2; increase sweep gas flow to decrease pCO2–more gas leaves oxygenator
VA-for cardiac support
thrombolysis in PE
cardiac arrest and unstable w/o contraindication
dexdedetomidine
lower delirium, not lower hosp LOS or vent days
sedation bundle
ABCDE: Awakening and Breathing, Choosing sedation, delirium mgt (sleep, hydration, pain, vis/hearing), early mobilization and exercise
ECMO oxygenation
ECMO circuit + uncaptured venous return
Oxygen content, Oxygen delivery
CaO2=Hb x sat x 1.34 + PaO2 x 0.003
DO2= CO x (Hb x 1.34 ) x 10
transpulmonary pressure
Airway pressure - pleural pressure
transpulmonary pressure=risk of VALI
Acute eosinophilic pneumonia (AEP) dx criteria
acute onset febrile respiratory symptoms 25% eosinophils
no known cause of eos (e.g., drugs, infection)
Eos may be inc in blood and pleural fluid
Assoc with cigarette smoke
Succinylcholine contraindicatons
- History of malignant hyperthermia
- Hyperkalemia( but usualΔis small24hours
- Prolonged immobility(16daysICU–37% riskK≥6.5)
