Airway and Ventilation Flashcard 8
Rationale
C. Rationale: For respiratory arrest, only assisted ventilations are required. This is performed by providing positive pressure ventilation at a rate of 1 breath every 6 seconds. Providing chest compressions is only necessary if the patient is confirmed to be in cardiac arrest, which can occur at any time in this situation. After 2 minutes of mouth-to-mouth resuscitation, check the patient’s pulse and breathing.
Question
You are the sole rescuer to provide mouth-to-mouth ventilations to a patient with status asthmaticus in respiratory failure. What is the rate of assisted ventilation in this case?
a. 2 breaths every 30 chest compressions
b. 2 breaths every 15 chest compressions
c. 1 breath every 6 seconds
d. 1 breath every 10 seconds
Answer
c. 1 breath every 6 seconds
Rationale
A. Rationale: Confirm advanced airway placement with continuous quantitative waveform capnography. (ACLS Case: Respiratory Arrest)
Question
You have successfully intubated a cardiac arrest patient and would like to know if the tube is in place. Correct placement of the endotracheal tube is confirmed via:
a. Quantitative waveform capnography
b. Ultrasound
c. Fluoroscopy
d. Real-time CT scan
Answer
a. Quantitative waveform capnography
Rationale
C. Rationale: AHA guidelines recommend assisted ventilations with a bag-mask device or an advanced airway with 100% oxygen is necessary when respiratory rate is below 6 breaths per minute.
Question
You notice that a patient with COPD on the ward has a respiratory rate that is gradually declining. According to AHA guidelines, what respiratory rate would prompt you to begin ventilating the patient with a bag-mask device or advanced airway with 100% oxygen?
a. 10 breaths/min
b. 12 breaths/min
c. 5 breaths/min
d. 18 breaths/min
Answer
c. 5 breaths/min
Rationale
D. Rationale: Due to their rigidity, oropharyngeal airways are used only in unresponsive patients with no gag or cough reflex.
Question
Your EMS companion asks you when is the appropriate time to apply an oropharyngeal airway. You answer, “Oropharyngeal airways are only used…”
a. In awake, responsive patients
b. To suppress an excessive gag reflex
c. In patients who are coughing
d. None of the above
Answer
d. None of the above
