Normal pH -CORRECT ANSWER 7.35-7.45
<7.35 Acid
>7.45 alkalosis
respiratory alkalosis -CORRECT ANSWER pH> 7.45, PaC02 low, HC03 low
respiratory acidosis -CORRECT ANSWER pH < 7.35
PaCO2 > 45
Hc03 normal 22-26
Metabolic alkalosis -CORRECT ANSWER pH > 7.45
HCO3 > 26
PaC02 45-35
normal oxygen level -CORRECT ANSWER 80-100
mild hypoxemia -CORRECT ANSWER 60-80
moderate hypoxemia -CORRECT ANSWER 40-60
severe hypoxemia -CORRECT ANSWER <40
A-a gradation calculation is a calculation of what? -CORRECT ANSWER level of
hypoxia
PA02-Pa02
A-a gradiant varies with age, calculation -CORRECT ANSWER 2.5 + 0.21 x age in
years
5 causes of hypoxemia -CORRECT ANSWER VQ mismatch
shunt
PNA, interstitial lung dz
hypoventilation
high altitude
clinical symptoms that require intubation -CORRECT ANSWER neuromuscular
depression or failure.
, spinal cord injuries
Guillain barre syndrome
trauma-spinal cord injuries, phrenic nerve injury
myasthenia gravis
shock
status asthmaticus
sustained apnea of any kind
indications for weaning from vent -CORRECT ANSWER underlying process that
required the vent is corrected
maintaining oxygen status
no presser support- levophed, epinephrine, etc.
Pa02 >80, FI02 of 0.5, and PEEP <8.0 cm H20
prior to separation from the vent proceed with this ...... to determine if pt. is able to dc
vent -CORRECT ANSWER trial of spontaneous breathing
Volume targeted assist control (AC) mode -CORRECT ANSWER the clinician
determines tidal volume and rate/ pt. can still breath over the vent. example: pt. gets RR
of 12 but has an additional 2 breaths on their own, pt. will still breathe 14 breaths/min.
tidal volume is based on the vent.
Synchronized intermittent mandatory ventilation SIMV -CORRECT ANSWER clinician
sets rate, and tidal volume, and peak inflation pt. can also have their own breaths. tidal
volume is set based on the patient. VENT doesn't specify tidal volume.
Pressure Control -CORRECT ANSWER A mode of ventilation that is normally patient or
time triggered, pressure targeted and time cycled.
AC control vent settings how do you determine tidal volume? -CORRECT ANSWER is
based on ideal body weight. careful with obese patients.
tidal volume -CORRECT ANSWER Amount of air that moves in and out of the lungs
during a normal breath
peep -CORRECT ANSWER positive end expiratory pressure
Static Pressure -CORRECT ANSWER the pressure of air at rest, or that portion in
moving air, if the air stream were to stop
Plateau pressure -CORRECT ANSWER Measures the compliance the entire lung
End inspiratory pause button
Peak pressure -CORRECT ANSWER Pressure required to get a volume of air into the
lungs, fighting resistance
