The ESI levels are numbered one through five, with levels one and two indicating the greatest urgency based on patient acuity. However, levels 3, 4, and 5 are determined not by urgency, but by the number of resources expected to be used as determined by a licensed healthcare professional (medic/nurse) trained in triage processes.

The original definition of emergency in 1940, when ASA classification was first designed, was "a surgical procedure which, in the surgeon's opinion, should be performed without delay," [1] but is now defined as "when [a] delay in treatment would significantly increase the threat to the patient's life or body part."

Visual acuity, the behavioral ability to resolve fine image detail; Care acuity, a level of physical, mental, or behavioral healthcare that's more specialized and intensive, and is provided to people with complex health needs. [1] Tactile acuity, resolving fine spatial details with the sense of touch
The Jaeger chart is an eye chart used in testing near visual acuity.It is a card on which paragraphs of text are printed, with the text sizes increasing from 0.37 mm to 2.5 mm. [1] This card is to be held by a patient at a fixed distance from the eye dependent on the J size being read.
Most simply, the general purpose of triage is to sort patients by level of acuity to inform care decisions; so that the most people possible can be saved. [63] Although a multitude of systems, color codes, codewords, and categories exist to help direct it, in all cases, triage follows the same basic process.
Also used were 40,000 diagnostic conditions and problems describing patient care needs. [28] The CCC System is a standardized framework consisting of four levels designed to allow nursing data to flow upward as well as downward. At the highest level the CCC System Framework consists of four healthcare patterns (Saba, 2007): [29] Health Behavioral
An early warning system (EWS), sometimes called a between-the-flags or track-and-trigger chart, is a clinical tool used in healthcare to anticipate patient deterioration by measuring the cumulative variation in observations, most often being patient vital signs and level of consciousness. [1]
The ISS scores ranges from 1 to 75 (i.e. AIS scores of 5 for each category). If any of the three scores is a 6, the score is automatically set at 75. Since a score of 6 ("unsurvivable") indicates the futility of further medical care in preserving life, this may mean a cessation of further care in triage for a patient with a score of 6 in any ...
