Ventilator Flashcards
Surface tension causes cohesion of the pleura creating a _______environment in the pleural space due to constant ________of the lung tissue.
A. Atmospheric
B. Sub-atmospheric ———> correct answer
A. Retraction ———-> correct answer
B. Expansion
Which of the following are least likely to require MV?
- Pulmonary edema from CHF
- Feline asthma
- Stridor from lara para ——> correct
- Pulmonary contusions
Look at the main complications: circuit disrupted, high pressure, walk through the loops, look at scalers.
Loops most important for techs
Dysynchrony - don’t just assume sedation needs to be increased. Was there a physiological change? Don’t mask that. Uncomfortable? Painful? Breathing over MV and need to switch modes?
Which of the following should be a priority before venting the patient?
A. Setting up vent
B. Placing art cath
C. Planning induction & intubate —> answer
D. Client consent
Acute restrictive breathing on MV with paradoxical breathing.
Could be pleural space Dz: pneumo?
Which of the following patients will benefit most from MV?
A. A dog with aspiration pneumonia from vomiting, PaO2 of 70 on room air, PaO2 of 90 with flow by
B. NCPE from choking. Can’t get an ABG. Patient in respiratory distress —> answer
C. A dog who received Valium, pento, and propofol to stop seizures secondary to a neuro toxin. Decreased resp effort and PaO2 of 75 on flow by and a PaCO2 of 38
D. Dog HBC with pulmonary contusions, panting, pink MMB, PaO2 70, PaCO2 30, oxygen nasal line at 5L/min
Which of the following is considered the best approach to lung protective strategy during MV?
A. Low tidal volume and low respiration rate with pressure control ventilation
B. High peak airway pressure with volume control ventilation
C. High tidal volume and high respiratory rate with high peak values with volume control ventilation
D. High resp rate, low tidal volume and pressure control ventilation —> answer
Define the conducting zone
Serves only to deliver air to the respiratory zone.
Starts with the trachea branching to the bronchi, segmental bronchi, to the terminal bronchioles.
No alveoli.
