/. Normal pH - Answer-✅7.35-7.45
<7.35 Acid
>7.45 alkalosis
/.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.
/.AC control vent settings how do you determine tidal volume? - Answer-✅is based on
ideal body weight. careful with obese patients.
/.tidal volume - Answer-✅Amount of air that moves in and out of the lungs during a
normal breath
/.peep - Answer-✅positive end expiratory pressure
/.Static Pressure - Answer-✅the pressure of air at rest, or that portion in moving air, if
the air stream were to stop
/.Plateau pressure - Answer-✅Measures the compliance the entire lung
