All plants are producers, or autotrophs, which means they create their energy (or food) through a process called photosynthesis. In this lesson, we characterize producers by 3 main traits: producers make their own food; producers cannot physically move; and producers provide food and shelter for animals.
The Emergency Severity Index (ESI) is a five-level tool for use in emergency department (ED) triage. Experienced ED nurses use the ESI to rate patient acuity, from level 1 (most urgent) to level 5 (least resource intensive). The ESI is unique among triage tools, by including both acuity and resource needs in the system of categorizing ED patients.
What is a STEMI? ST-Elevation Myocardial Infarction (STEMI) is a very serious type of heart attack during which one of the heartâs major arteries (one of the arteries that supplies oxygen and nutrient-rich blood to the heart muscle) is blocked. ST-segment elevation is an abnormality detected on the 12-lead ECG. It is a profoundly life-threatening medical emergency and usually associated with a disease process called atherosclerosis (coronary artery disease). You can find a useful video about heart disease and heart attacks at the Khan Academy.
