Orthostatic Hypertension Flashcards
(14 cards)
Hyperglycemia leads to volume depletion
causes polyurea
criteria of orthostatic hypotension
20mmHg or greater decrease in systolic BP
10mmHg or greater decrease in diastolic BP
important factors orthostatic hypotension
Age Vomiting Diarrhea Hemorrhage Hyperglycemia Fever
Drugs & Meds associated associated w/ orthostatic hypotension
ETOH
anti-HTN
anti-depressants
Sx of orthostatic hypotension
weakness lightheaded blurred vision nausea pallor- parasympathetic vasoconstriction diaphoresis -sympathetic outpouring headache - prodrome or response to low perfusion palpitations - syncope - pass out
Cardiogenic Shock categories
Hypovolemic
cardiogenic
distributive
combined
cardiogenic shock definition
acute state of decreased CO resulting in inadequate tissue perfusion despite adequate circulating BVolume
*Worst manifestation of decompensated <3 Failure
cardiogenic measurements
systolic BP < 90 mmHg
severe reduction in cardiac index < 2.2L/min/m2
elevated filling P: PCWP>18mmHg
preshock signs
tachycardia
mild change in BP
restless/agitated
pale skin
preshock
rapid compensation of diminished tissue perfusion by homeostatic mechanisms
shock
compensatory mechanisms overwhelmed and End Organ Damage begins
shock signs
tachycardia hypotension tachypnea oliguria confused lethargic cool/clammy skin
end organ failure (shock stage)
progressive EOD (end organ death) leads to irreversible organ damage & death
end organ failure signs
cardiac arrest respiratory failure anuria obtunded mottled skin
