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
