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.
Surgery is indicated when the signs and symptoms correlate with the radiologic evidence of spinal stenosis. Generally, surgery is recommended when significant radiculopathy, myelopathy (cervicothoracic), neurogenic claudication (lumbar), or incapacitating pain is present.pidural steroid injection (ESI) provides aggressive-conservative treatment for patients with lumbar spinal stenosis (LSS) who demonstrate limited response to oral medication, physical therapy, and other noninvasive measures.
