This is a timed quiz. You will be given 60 seconds per question. Are you ready?
Almost all documented cases of inappropriate shocks have been attributed to human error, such as using the AED in a moving vehicle or operating it on a patient with a pulse.
The maximum dosage amount is three tablets, or sprays, without additional medical direction.
Oxygen-poor blood arrives in the right atrium and is pumped out through the right ventricle via the pulmonary arteries, to the lungs.
You are dispatched to a 65-year old male who is complaining of severe chest pain, and has a history of cardiac problems. What is the primary role of medical direction in this scenario?
An AED should only be applied when the patient does not have a pulse nor respirations.
The Tricuspid Valve is located BETWEEN the RIGHT ATRIUM and RIGHT VENTRICLE
The next step after shocking with the AED, and the patient is breathing and has a pulse, is to apply high concentration oxygen via NRB. If the respiratory rate is above or below the minimum and maximum limits, however, you would assist with a bag valve mask.
If this patient becomes too bradycardic or tachicardic, they may go unconscious due to inadequate perfusion.
It is impossible to determine the actual degree of tissue damage in the field, so the purpose of the focused assessment is to gather information for the receiving facility. You should always ask about medications; it is the M of SAMPLE. The focused history has nothing to do with AED use. Cardiac pain has all sorts of presentations, making it difficult to differentiate from other conditions.
The lower chambers of the heart (left and right) are both called the "ventricles".
Pulmonary veins return oxygen-rich blood from the lungs to the left atrium, where it is sent to the left ventricle and pumped to the rest of the body.
Due to the fact the patient had been running the elevated pulse is perfectly within normal limits
Because Nitro is a Vasodilator it should not be administered to a patient with a systolic blood pressure of below 100, because it may cause their blood pressure to drop to a dangerous level.
With this patient you could suspect many things, however the best choice is coronary artery disease.
Because nitro is a vasodilator you should always check the patient's blood pressure after giving nitro and before giving another dose.
