what can be injected into the red balloon port? - ANSWER-1.5
mL or less of air
what to do when pt starts deteriorating - ANSWER-call when
concerned. give providers a clear picture of what is going on.
use communication tools to communicate your concern
CUS - ANSWER-I am Concerned
I am Uncomfortable
This is a Safety issue
which port should you use to infuse calcium chloride? -
ANSWER-clear/white
what can be infused through the yellow port? - ANSWER-
3mL/hr NS flush
RN role with PAC - ANSWER--use ports appropriately
-level, zero, square wave, waveform analysis
,-prevent infection
-measure skin to tip q4h and document changes from
placement measurement
-print PA wave strip and ECG strip
-site care prn or once a week
-d/c lines asap w/ order
PAC safety - ANSWER--secure device
-do not tape over plastic sheath
-monitor for wedging
-monitor for ventricular placement
-assure you are getting quality data
injury to alveoli - ANSWER--causes release of proinflammatory
cytokines
-cytokines recruit neutrophils to the lungs
-neutrophils become active and release toxic mediators
-damage to capillary endothelium and alveolar epithelium
-proteins leak out from vascular space
-normal oncotic gradient, fluid doesn't stay where it should.
gets into airways and interstitial spaces
ARDS s/s - ANSWER--hypoxemia after pulmonary insult
-bilateral opacities
-crackly lungs
,-diaphoresis
-chest pain
-cough
-accessory muscle use
-rapid deterioration
-increasing demand for supplemental oxygen
ARDS treatment - ANSWER--treat underlying cause
-prevent progression of lung injury
-promote gas exchange
-high pressure ventilation (PEEP)
-high level O2 therapy to keep PaO2 >60
-support tissue oxygenation
-prevent complications
ARDS management strategies - ANSWER--low tidal volume
ventilation
-recruit PEEP
-monitor plateau pressure
-pulmonary vasodilatos
-neuromuscular blockers
-proning
-ECMO
, low tidal volume ventilation - ANSWER-goal is <6mL/kg to
prevent over distending alveoli. helps sustain surfactant
production
recruiting PEEP - ANSWER-keeps alveoli open, improving
oxygenation using lower FiO2. this however can drop pt's BP
due to decreased venous return and can also cause
barotrauma
precedex should not be used due to light sedative properties
assessments for effectiveness of NMB - ANSWER--TOF
-spontaneous breathing or movement
-resistance to turning
-diaphoresis
-vitals
-ETCO2
Train of four monitoring - ANSWER--series of four twitches at 2
hz, every half second for 2 sec.
-reflects blockade percentage
-TOF based on provider order for pt's clinical goals
4 twitches: 0-75% of receptors blocked
3: 80%
