🏷️ Respiratory insufficiency- primary cause for admission to CICU.
🏷️ Liberation from IMV in CICU- needs careful planning and evaluation
🏷️ Research incorporating unique CICU population will better define optimal treatment paradigms
🏷️ SBTs physiologically demanding
🔥 prior Volume & BP optimization is key
🏷️ ongoing vasopressor use not a CI
🏷️ ensure arrhythmias quiescent
🏷️ identify respiratory failure signs during SBT
🏷️ common modalities used:
T-piece, CPAP, PS; low level PS most common in #CICU
Current guidelines focus on the t/t of inciting event & restore end-organ perfusion; inotropes/pressors to target MAP ≥65 mm Hg.
🏷 Asses serial markers of systemic perfusion- lactate, ScVO2, UOP, Cr, LFTs, mentation, temp, and invasive hemodynamics & target accordingly
🏷Difference in #SCAI classes A-B & C-E is presence of hypoperfusion- clinical signs like cool mottled skin, poor UOP, confusion, & biochemical abnormalities like ⬆️ lactate, renal insufficiency, and ⬆️ LFTs.
🏷 RAP, ⬆️ shock stage over time, and late deterioration ⬆️ mortality
