researchers recorded EEGs from several thousand patients and volunteers anesthetized with a range of commonly used anesthetics and anesthetic combinations.
The changes in the BIS algorithm resulting from updating and refinement of the producer's database make it difficult to compare results obtained by different investigators using different versions of the BIS monitor.
To drop an index in a database, you need to use a specific SQL command. First, you identify the name of the index you want to drop. Then, you use the DROP INDEX statement followed by the name of the index. This command removes the index from the database, making the associated data searchable without the index.
one of several systems used in anesthesiology as of 2003 to measure the effects of specific anesthetic drugs on the brain and to track changes in the patient's level of sedation or hypnosis
Index on a table in the database is just like an index (or content page) in a book - a quick look at an index can tell you where the actual data is located. This saves time and cost of scanning the whole table, thus making the database faster.
BIS reduces the risk of patient awareness during surgery as well as lowering hospital costs by speeding patient recovery and reducing the overuse of anesthetic agents.
the Patient State Analyzer, or PSA 4000, which is also based on EEG data; and the A-Line (R) monitor, which processes signals derived from auditory stimuli.
It is a database, either a manual card index or an electronic computer system.
The word database is a noun that means a collection of data. Some words that are synonyms for database are directory, index, and table.
A database, as used by a computer, is a software programme that is used to store data (information). A card index is also a database, written on pieces of card - so, technically, a card index is a physical thing (hardware?), possibly.
Bispectral analysis is a method of analyzing the mathematical relationships among the various components of an EEG signal (phase couplings) as well as measuring amplitudes and frequencies.
Table, index, trigger and column Table, index, trigger and column
The BIS system displays both raw data from the EEG and a single number between 100 (indicating an awake patient) and 0 (indicating the absence of brain activity) that represents the patient's degree of sedation.
