2026 PRACTICE SOLUTION STUDY GUIDE
◉ respiratory aklalosis. Answer: pH> 7.45, PaC02 low, HC03 low
◉ respiratory acidosis. Answer: pH < 7.35
PaCO2 > 45
Hc03 normal 22-26
◉ Metabolic alkalosis. Answer: pH > 7.45
HCO3 > 26
PaC02 45-35
◉ normal oxygen levle. Answer: 80-100
◉ mild hypoxemia. Answer: 60-80
◉ moderate hypoxemia. Answer: 40-60
◉ severe hypoxemia. Answer: <40
,◉ A-a gradiatian calculation is a calculation of what?. Answer: level
of hypoxia
PA02-Pa02
◉ A-a gradiant varies with age, calculation. Answer: 2.5 + 0.21 x age
in years
◉ 5 causes of hypoxemia. Answer: VQ mismatch
shunt
PNA, interstitial lung dz
hypoventilation
high altitude
◉ clinical symptoms that require intubation. 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. 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 seperation from the vent proceed with this ...... to
determine if pt is able to dc vent. Answer: trial of spontaneous
breathing
◉ Volume targeted assist control (AC) mode. 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. 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. Answer: A mode of ventilation that is normally
patient or time triggered, pressure targeted and time cycled.
