exam 4- cardiac 2 Flashcards
Heart Failure
what falls
what is leading risk factors x2
Cardiac Output falls in hf
Leading risk factor- heart disease and a past mi
Left sided heart failure- results in
what congestion
what output
pulmonary congestion
decreased cardiac output
s/s of early left sided heart failure
x2
fatigue
activity intolerance
s/s of late left sided heart failure
x6
syncope ,
dizziness,
dyspnea,
cough,
orthopnea
cynaosis
right sided heart failure
what becomes distended
where does blood back up
Right ventricle and atria become distended
Blood backs up to systemic supply
s/s of right sided heart failure
x2
depdedent edema
jvd- distended neck veins
Hemodynamic Monitoring
evaluates what function/ response
can be used for
not used to
evaluate cardiac and circulatory function
and response to interventions-
Can be used for blood sampling
but not to give medications
Hemodynamic Monitoring
placed where
monitors;

b
a p
c v p
p p
c o
catheter is placed into major blood vessel to monitor
.hr
.bp
.arterial pressure
.central venous pressure
Pulomary pressure
Cardiac output
Hemodynamic Monitoring
measures what
converts to what
put where
Measure pressure within a vessel
converts to an electrical waveform
Catheter is threaded into radial artery or vein
what is used to prevent clotting
what type
hemodynamic monitoring
IV fluids are used to prevent clotting
Normal Saline
allows direct continuous monitoring of
what 3 pressures
Intra-arterial pressure monitoring (Art Line)-
allows direct continuous monitoring of
systolic,
diastolic,
and mean arterial pressures
also draws
needs what
Intra-arterial pressure monitoring (Art Line)-
Can draw abg-
needs pressurized bag of saline that drips slowly but continually to get right reading
why is map looked at
degree
tissue
average
degree of tissue pressure,
tissue perfusion
or average pressure is arteries during cycle
what is map affected by
x4
blood volume
the ability of the heart to pump
vessel diameter
ability of heart to stretch
what is normal map
is less then 50 then what
if over 105 then what
70-90
- if less then 50 then decreased tissue perfusion
- if over 105 then there is increase in atherosclerotic vessels or fluid overload
Ways to find map-
cardiac output x svr
(systolic + 2x diastolic)/3
Venous Pressure Monitor- CVP-
monitors what
placed where
ends up where
monitors fluid balance of a pt
placed into jugular / subclavian vein
goes into superior vena cava or rt atrium
what is normal cvp
normal is 2-8 cm of h20
low cvp means
low
s
a
d
low fluid volume
shock
anemia
dehydration
high cvp means-
fluid
vaso
more
also seen in
fluid excess,
vasoconstriction,
more blood rushing back to heart,
also seen in cardiac tamponade
cardiac tamponade-
what is it
does waht
fluid is built up in pericardial sac
puts pressure on heart
Pulmonary Artery Pressure- Swanz-Ganz
evaluates what
Cath is lodged where
evaluates left ventricle and overall cardiac function
cath is lodged into pulmonary artery
has multiple lumens that takes pressure from
x3
Pulmonary Artery Pressure- Swanz-Ganz
right atria,
pulmonary artery
left ventricle
pressure increased with x2
Pulmonary Artery Pressure- Swanz-Ganz
left heart failure,
pulmonary congestgion
when is pressure decreased
Pulmonary Artery Pressure- Swanz-Ganz
pressure decreased with hypovolemia
normal pulmonary pressure
Pulmonary Artery Pressure- Swanz-Ganz
pulmonary pressure is 25/10

Potential Complications with hemodynamic monitoring devices
Bleeding
Pneumothorax-especially in ones that have central line ot heavy catheter that goes directly into heart
Dysrhythmias- irritates heart
Infection
Embolism
calibration-
measuring when
maintaining what
monitor what
nursing consideration with hemodynamic monitoring devices
Calibration- measure when in the right atria and in right place
Measuring between breathes
Maintain pressure in flush solution
Monitor trends- sharp changes may not be accurate
what checks placement
what technique
assess
removing line- pressure how long/ take what into consideration
nursing consideration with hemodynamic monitoring devices
CXR to check placement
Aseptic technique
Assess site
Removing line- apply pressure for 5-15 minutes and take any anticoagulants into consideration
Cardiac Transplantation
Criteria-
what age
likely for what
<65,
and is likely to have 1 year to live after
Surgical procedure-heart transplants
hypothermic- needs what to prevent what
may need
surgery can cause
Hypothermic –need to rewarm slowly after to prevent severe electrolyte shifts
May need permanent or temp pacemaker
Surgery can cause short term memory loss
post op concerns-heart transplants
Infection- put on
put on antibiotics
Concern for rejection- heart transplants
placed on
rejection how long after
post op concerns
placed on immunosuppressants
Rejection can happen immediate ot months later
post op concerns-Rejection s/s

heart transplants
dyspnea,
fatigue,
edema

post op concerns-Denervation-
may have
put on
heart transplants
may have slow response to stress and activity-
put on anticoagulants and steroids after-
post op concerns-denervation
what therapy
complete
up to date
medical
heart transplants
cardiac therapy,
complete incentive spirometer
, stay up to date on vaccines
medical asepsis
post op concerns goal
heart transplants
Goal is to discharge pt home
