Norepinephrine dose
Low: 0.15 mcg/kg/min
High: 2 mcg/kg/min
HCM PE will show harsh crescendo-decrescendo systolic murmur which
increases in intensity with Valsalva maneuver
decreases with squatting
HCM management
Management includes refraining from vigorous physical activity
Rx options: beta-blockers or calcium channel blockers
clonidine overdose rx
nalaxone
Although difficult to distinguish from opioid intoxication, clonidine more commonly causes hypotension and bradycardia.
Naloxone may improve respiratory depression and mental status by an unknown mechanism in clonidine overdose.
HCM murmur
murmur that increases with maneuvers that decrease preload
PE will show harsh crescendo-decrescendo systolic murmur which increases in intensity with Valsalva maneuver and decreases with squatting
