Final answer:
Pulmonary edema and impaired ventilation are symptoms of cardiogenic shock, which is caused by the heart's failure to maintain adequate cardiac output.
Step-by-step explanation:
Pulmonary edema and impaired ventilation occur during cardiogenic shock. This type of shock results from the heart's inability to maintain sufficient cardiac output, often due to a myocardial infarction, arrhythmias, valve disorders, or other heart conditions. With cardiogenic shock, the heart's reduced function leads to a buildup of fluid in the lungs (pulmonary edema) and difficulty in breathing, as the compromised heart cannot effectively circulate blood and remove fluid from the lung's air sacs.
