<7.35 Acid
>7.45 alkalosis
respiratory aklalosis Ans:— pH> 7.45, PaC02 low, HC03 low
respiratory acidosis Ans:— pH < 7.35
PaCO2 > 45
Hc03 normal 22-26
Metabolic alkalosis Ans:— pH > 7.45
HCO3 > 26
PaC02 45-35
normal oxygen levle Ans:— 80-100
mild hypoxemia Ans:— 60-80
moderate hypoxemia Ans:— 40-60
severe hypoxemia Ans:— <40
A-a gradiatian calculation is a calculation of what? Ans:— level of
hypoxia
PA02-Pa02
A-a gradiant varies with age, calculation Ans:— 2.5 + 0.21 x age in
years
, Page | 2
5 causes of hypoxemia Ans:— VQ mismatch
shunt
PNA, interstitial lung dz
hypoventilation
high altitude
clinical symptoms that require intubation Ans:— 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 Ans:— 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 Ans:— trial of spontaneous breathing
Volume targeted assist control (AC) mode Ans:— 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 Ans:— clinician
sets rate, and tidal volume, and peak inflation pt can also have their own
