PRACTICE SET WITH EXPLANATIONS A+
◉ 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
End inspiratory pause button
◉ Peak pressure. Answer: Pressure required to get a volume of air
into the lungs, fighting resistance
◉ increase in peak pressure is a complication from which patients?.
Answer: ARDS or restrictive airway patients.
◉ high peak pressures with normal plateau pressures indicate.....
Answer: resistance, such as an ET obstruction or bronchospasm
◉ Minimal sedation. Answer: relief of anxiety, minimal affection on
sensorium, anti-anixety medications
◉ moderate sedation. Answer: -Depression of consciousness is drug
induced
-Patient is able to respond to verbal commands
-Cardiac and respiratory function not usually affected
