NO-Chp 19 Flashcards
What deactivates NO
metals, oxygen, and reactive oxygen species
Endogenous NO
vasodilation, platelet inhibition, immune regulation, NT
Exogenous NO
Donors; release NO or related NO species; organic nitrated(nitroglycerine) & sodium nitropruisside
NO in infants
hypoxic resp. failure, reducing pulm. artery resistance and pressure and improved perfusion
NO adults
for pulm. HTN, acute hypoxemia, and cardiopulm. resusitation
Phosphodiesterase inhibitors
terminate effects pf NO, which breakdown cGMP to GMP; allows cGMP to persist longer and accumulate (Sildenafil)
Effects of NO
decrease BP, vasodilator, antithrombotic effects
DM and NO
endothelial cells are dysfunctional and produce less NO, results in abnormal platelet function and thrombosis
