Question Answer
A person who can only speak phrases is most likely in _______ respiratory distress.
Show Answer
moderate (*severe=words)
What brain structure is the 1st to detect oxygenation problems?
Show Answer
Cerebral cortex (source of mental status changes)
How does a large bore ET tube decrease work of breathing?
Show Answer
There is less airway resistance (when compared with a small bore ET tube).
Volume or Pressure Ventilation? Controlled Mandatory Ventilation, (CMV), Assist Controlled Ventilation (ACV), and Synchronized Intermittent Mandatory Vent (SIMV).
Show Answer
Volume ventilation
_______ ventilation is the type where peak inspiratory pressure is controlled and tidal volume (V+) varies.
Show Answer
Pressure ventilation
What should be done if a patient develops dysrhythmias during suctioning?
Show Answer
Stop suctioning
What type of respiratory failure can occur even when the patient has perfectly normal lungs?
Show Answer
Hypercapnic (*can be due to obesity, brain injury, muscle fatigue, neuro-muscular disease, etc.)
_______ failure results from an interruption of O2 transfer into the blood.
Show Answer
Hypoxemic resp. failure
What can cause hypoxemic respiratory failure?
Show Answer
Pneumonia, pulmonary edema, PE, smoke inhalation, ventilator induced injury, heart failure, and shock.

How could gastric or bowel dilation decrease CO in an intubated patient?
Show Answer
Swallowed air compresses the vena cava and decreases CO. Also prevents adequate diaphragmatic excursion.
Use of accessory muscles signifies _______ respiratory distress.
Show Answer
moderate
_______ ventilation is the suggested type of ventilation for patients with ARDS.
Show Answer
Low volume (VT of 6 mL/kg)
_______ can occur if the respiratory rate or VT is set too high on a ventilator.
Show Answer
Respiratory alkalosis (from alveolar hyperventilation)
What complications can develop from metabolic alkalosis?
Show Answer
Difficult weaning, hypokalemia, hypocalcemia, dysrhythmias, neuromuscular irritability, seizures, coma, and death.
What vent related problem causes it?
Show Answer
Caused by hyperventilation (COPD).
Each attempt to intubate a patient should be limited to _______.
Show Answer
30 seconds
Type of ventilation? Supports weaning. Delivers set FIO2 and allows the patient to control rate and volume of spontaneous breaths. Increases WOB.
Show Answer
Synchronized Intermittent Mandatory Ventilation (SIMV)
Hypoxemic respiratory failure is defined as a PaO2 of _______ or less while a patient is on supplemental O2 _______% or more.
Show Answer
PaO2 = 65 or less; O2 = 60% or more
