4 Cardiology and Resuscitation Free Online FlashCards

Does a normal initial blood pressure rule out a serious cardiac problem?

No. A serious cardiac problem can exist despite a normal initial blood pressure; assess the whole patient and repeat vital signs to watch for trends.

How can cardiac ischemia present besides sharp chest pain?

Cardiac ischemia may feel like pressure, tightness, heaviness, or discomfort rather than sharp pain. Symptoms may also include shortness of breath, nausea, sweating, weakness, or lightheadedness.

How long should a healthcare professional check for a pulse?

Check for a definite pulse for no more than 10 seconds. If no definite pulse is felt, begin CPR; avoid checks that delay compressions.

What are the adult CPR compression rate and depth targets?

Compress at $100\text{–}120$ per minute, to a depth of at least 2 inches $5 cm$, while avoiding depths over 2.4 inches $6 cm$ for an average adult.

What should rescuers do after AED rhythm analysis or shock delivery?

Immediately resume CPR, starting with compressions, whether a shock is delivered or the AED advises no shock.

What CPR ratios are used for children with one rescuer versus two?

Use $30:2$ with one rescuer. With two rescuers for a prepubertal child, use $15:2$.

How should you respond when a patient has a pulse but inadequate breathing?

Provide ventilations and frequently reassess breathing and pulse. Do not perform chest compressions unless cardiac arrest develops.

What takes priority when suspected opioid poisoning includes cardiac arrest?

Support airway and breathing, activate EMS, and give naloxone when authorized and available. If the patient is in cardiac arrest, CPR and AED care take priority; naloxone must not delay resuscitation.

What care follows return of spontaneous circulation?

Reassess airway, breathing, pulse, mental status, and vital signs; provide supportive care, monitor for deterioration, and transport with an appropriate handoff.

What signs can indicate poor perfusion?

Altered mental status, pale or cyanotic skin, cool or clammy skin, weak pulses, delayed capillary refill, dizziness, or hypotension can indicate poor perfusion.

Can EMTs rule out acute coronary syndrome in the field?

No. EMTs cannot rule out acute coronary syndrome in the field, so suspected ACS should be treated as time-sensitive.

What are key EMT priorities for suspected ACS?

Minimize exertion, obtain and trend vital signs, request appropriate resources, and transport promptly. Give or assist with medication only when authorized and permitted by protocol.
