CPR CPR for Special Situations 3

Question 1

What are the 'H's and T's' in CPR?

Accepted Answer

Reversible causes of cardiac arrest (Hypoxia, Hypovolemia, Hydrogen ion, Hypo/Hyperkalemia, Hypothermia; Tension pneumothorax, Tamponade, Toxins, Thrombosis)

Answer

The H's and T's are a memory aid for the reversible causes of cardiac arrest — identifying and treating these can restore a perfusing rhythm.

Question 2

How should CPR be performed in a confined space (e.g., an airplane seat)?

Accepted Answer

Move the victim to an aisle or flat surface if possible; if not, compressions may be done from behind the seat

Answer

Effective chest compressions require the victim to be on a firm, flat surface — in confined spaces like aircraft, move the victim to the aisle and position them on the floor if at all possible.

Question 3

What is hypothermia's effect on CPR, and what modification is needed?

Accepted Answer

Hypothermia can cause cardiac arrest; CPR is performed, and victims should be rewarmed — 'not dead until warm and dead'

Answer

Severe hypothermia can cause cardiac arrest and mimic death; victims should receive standard CPR with gentle rewarming because survival has been reported even after prolonged cold-water immersion — 'not dead until warm and dead.'

Question 4

A bystander witnesses a person with a known seizure disorder fall and become unresponsive. What is the first priority?

Accepted Answer

Check for responsiveness and breathing to determine if CPR is needed

Answer

Regardless of seizure history, an unresponsive person must be assessed for responsiveness, normal breathing, and pulse to determine whether CPR is needed.

Question 5

What is the effect of CPR feedback devices on resuscitation quality?

Accepted Answer

They provide real-time audio/visual cues on rate, depth, and recoil, which improve CPR quality and outcomes

Answer

Real-time CPR feedback devices that monitor rate, depth, and full recoil have been shown to improve CPR quality and are recommended for use in both training and clinical settings.
