section 1 Flashcards
what is systolic BP
measure the extent of force extered against the arteries during the ejection cycle
why do we care about BP
it is a non-invasive performance measure on the effectivness of the hearts pumpuing
what is the max that a diastolic BP can raise or decrease
10
at what systolic and diastolic should the exercise program be discontinues
210
110
what is pulse pressure
the different between diastolic and systolic BP
what is the normal chnage in pulse pressure e
40 - 50 mmgh
is an ABI great then 1.0 still consider normal
yes the pressure in our legs inn 10-20% highere then the brachial art
what is the valsalva maneuver
a breathing technique that involves forcefully exhaling against a closed glottis
unclogging ears
what is stable SBP indicative of when one is exercising
a decrease CO
what should happen to BP following then conclusion of exercise
3 min rule
the post SBP should be less then 90% of the systolic at peak exercise
what is a arterial line used for
a thin, flexible tube inserted into an artery to help doctors and nurses monitor blood pressure and take blood samples
taking BP and an aterial line
do not take BP above the infusion site
can someone eat or drink with an NG tube
nope
can NG be disconnected
yes for mobility
what level should a chest tube be kept at
below the level of insertion
what is PE
the blockage of the pulmonary artery or one of its branches
what is the clinical presentation of a PE
difficulty breathing, chest pain that often mimics heart attack, rapid pulse,
what are the risk factors for PE
surgery
long periods of inactivity
increased levels of clotting factors in the blood
abnormalities of the vessel wall
what is the treatment for PE
anticoagulant med - heperin and warfarin
what is hypovolemic shock
insufficient circulating blood
primary causes: hemorrage and severe burns
what is the clinical presentation of hypovolemic shock
hypo due lack of circulating volume
anxiety
AMS
cool and clammy skin
rapid and thready pulse
thirst
fatigue
what is the treatment of hypovolemic shock
positional management: supine legs elevated 12 inches as tolerated
controlled bleeding
infusion
what is autonomic dysreflexia
a massive sympathetic chnages that can occur in relation to spinal injury or disease
trigger -noxious stimuli > bladder distention, UTI, skin ulcerss, bowel impaction
what is the clinical presentatin of autonomic dysreflexia
sweating above the level of lesion
flushing above the level of lesion
increase BP
blurred vision
slowed HR
