Define perfusion blood flow and oxygen delivery to body tissues
-activates SNS
-releases angiotensin II (activates RAAS0
how does alcohol elevate BP? -impairment of baroreceptor reflexes
-breathing rate
-O2 saturation
-color of skin/lips/nails
how do you assess adequate -chest/back symmetry
ventilation? -clear breath sounds
-trachea midline
how do you measure BP? CO x peripheral vascular resistance
how do you measure CO? stroke volume x HR
how do you measure MAP? CO x TPR
systolic pressure - diastolic pressure
how do you measure pulse pressure?
-orientation to time/place/person/situation
-pulse rate between 60 & 100
how do you recognize adequate -extremities warm
perfusion? -capillary refill time
men 40+ - 2
women 40+ - 1
how much alcohol appears beneficial? with pre existing blood pressure
, -hypertension
-myocardial infarction
-heart failure
impaired perfusion is exemplified by:
-shock
-chest compliance (property of chest cage to expand)
-lung compliance (property of lungs to inflate)
movement of the chest cage depends -airway conductance (property of airways to allow flow)
on: -intrapleural pressure (low pressure in pleural cavities)
-volume of blood pumped from the heart
-radius of blood vessels
-viscosity of blood
Perfusion is influenced by -velocity of flow
-blood pressure
heart healthy lifestyle
-healthy diet
primary prevention methods for -exercise most days of the week
hypertension -no smoking
BP screening
-every 2 years when its 120/80
-every year when it is high
secondary prevention for Lipid screening
hypertension -men 35+
-women 45+
-nutrition therapy
-activity, exercise
-smoking cessation
-pharmacotherapy
-vasodilators
tertiary prevention for hypertension
-vasopressors
-diuretics
elasticity
what 2 key factors influence lung
surface tension
compliance?
