Pulmonary embolism labs
d-dimer
CBC
ABG
BNP
EKG
CXR
Spiral chest CT
-coagulation study
-duplex ultrasonography
-pulmonary angiography
- v/q scan
pulmonary embolism patho
occlusion of pulmonary arteries from a clot , decreased blood flow to alveoli allowing no gas exchange
-v/q mismatch prevents gas exchange
PE can lead to….
increase pulmonary vascular resistance because blood flow cannot move past the clot
**lead to HTN –> back flow of blood to R ventricle –> R sided HF
v / q scan
identifies lungs are ventilated but not perfused
*high probability = clot
pulmonary angiography
definitive PE study , invasive , only done when pt is stable and other tests are inconclusive
Pulmonary embolism action
- Provide O2 and ventilation
- anticoagulants
- IV fluids
- baseline aPTT / INR
pulmonary embolism meds
- oral xa inhibitors
- lovenox
- warfarin
- heparin
- tPA
oral xa inhibitors
used in asymptomatic PE pts w/ low risk clot
-eliquis , xarelto , prodaxa
lovenox
anticoagulant , low molecular weight heparin
heparin
anticoagulant , IV admin in emergency
heparin antidoate
protamine sulfate
tPA
dissolve current clot , occurs within 3 hours of event
given to UNSTABLE PTS
IV heparin
given for emergency PE
-complaints of chest pain
-hypoxemia
-tachypnea
-tachycardia
Heparin admin considerations
-bleeding precautions
-IV access
-protamine sulfate on hand
-aPTT levels
venous doppler US
evaluate blood flow of vessels
-check for DVT
inferior vena cava filter
allows for blood passage and traps other emboli
-used when pts have recurrent PE despite therapies
PE lifestyle change
- exercise
- cardiac diet
- adequate fluids
- no smoking
-bleeding precautions
PE home medications
explain Coumadin
follow ups for INR check
lasix and s/s of hypokalemia
PE bleeding precautions
soft toothbrushes
electric razor
limit activity with bleeding risk
fall precautions
warfarin antidote
vitamin K
s/s of DVT
lower edema
redness / warmth
warfarin and vit k foods
need to be limited
-leafy greens
-kale
-broccoli
-spinach
-cabbage
-lettuce
acute respiratory failure s/s
SOB
fever
cough
altered mental status
dyspnea
rapid shallow breathing
accessory muscle use
flushed skin
acute respiratory failure vitals
hypertension
tachycardia
tachypnea
low O2 sat
temp
ARF can include both what…
hypoxemia and hypercapnia
acute respiratory failure interventions
oxygen : NRBM 100%
cardiac monitoring
immediate IV access
HOB elevated
-neuro assessment
-vitals
-breath sounds
-IV fluids
acute respiratory failure oxygen option
BiPAP if nonrebreather isn’t enough
-maintains high pressure
acute respiratory failure labs
- CXR
- ABGs
- CBC
- EKG
- cardiac enzymes
- BNP
- sputum culture
- blood culture
acute respiratory failure meds
- IV antibiotics
- bronchodilators: albuterol
- corticosteroids : solumedtrol , solucortef
- sedatives : ativan
- diuretics : lasix
ARF complications
- sepsis
- dysrhythmias and decreased CO
- VAP
- stress ulcers
ARF sepsis complication
underlying pneumonia with hypoxemia and decrease CO leads to MODS
VAP prevention
sterile technique
handwashing
oral care
suctioning
ARDS interventions
- monitor vitals
- monitor O2 sat
- neuro assessment
- resp assessment
- monitor UO
- monitor ventilation
ARDS labs
ABGs
CBC
serum lactate
renal / liver tests
blood and sputum culture
ARDS meds
- antibiotics
- corticosteroids
- bronchodilators
- sedatives
- paralytic agent
- analgesics
- inotropic agents
ARDS tx
PRONING POSITION
-allows for better alveoli recruitment
ECMO
ECMO
pump that circulates blood through artificial lung , CO2 is removed and oxygenation happens
-blood is returned to pt
obstructive sleep apnea s/s
fatigue
daytime sleepiness
restless sleep
loud snoring
snorting
witnessed apnea during sleep
gasping / choking during sleep
OSA risks
type II DM
HTN
hyperlipidemia
obesity
smoking
male

OSA patho
upper airway is obstructed / narrowed during sleep related to pressure being put on airway
