Which feature of modern AEDs provides real-time feedback to rescuers during CPR?
Answer: Impedance-based chest compression depth and rate monitoring
Modern AEDs use transthoracic impedance sensing to detect chest compressions and provide real-time audio/visual feedback on depth and rate.
End-tidal CO2 (ETCO2) monitoring during cardiac arrest is MOST useful for:
Answer: Confirming correct tracheal tube placement and assessing CPR quality
ETCO2 confirms endotracheal tube placement and reflects cardiac output during CPR; a sudden rise often indicates return of spontaneous circulation.
A mechanical CPR device such as the LUCAS or AutoPulse is MOST appropriate in which scenario?
Answer: Prolonged resuscitation during patient transport or cardiac catheterization
Mechanical CPR devices deliver consistent compressions when sustained high-quality manual CPR is impractical, such as during transport or in the cath lab.
When using a defibrillator's synchronize mode for cardioversion, the shock is timed to which part of the cardiac cycle?
Answer: R wave
Synchronized cardioversion delivers the shock on the R wave to avoid the vulnerable T-wave period, which could induce ventricular fibrillation.
Point-of-care ultrasound (POCUS) during cardiac arrest can identify all of the following EXCEPT:
Answer: Ventricular fibrillation on the monitor
VF is diagnosed on the cardiac monitor/ECG, not by ultrasound; POCUS identifies reversible causes and confirms true PEA (no wall motion).
A 12-lead ECG acquired via a smartphone-connected device in the field is transmitted to the hospital. This technology PRIMARILY improves outcomes by:
Answer: Activating the cath lab before hospital arrival, reducing door-to-balloon time
Pre-hospital 12-lead ECG transmission enables cath lab activation before patient arrival, significantly reducing door-to-balloon time in STEMI.
During a code, which digital tool is MOST helpful for ensuring accurate medication dosing and timing documentation?
Answer: Resuscitation data recorder / code documentation tablet
Dedicated code documentation tablets or resuscitation data recorders timestamp interventions and drug administration in real time, reducing errors in high-stress situations.
