Flashcards in Chpt. 8 - Key Terms Deck (14):
1

Anatomic dead space

Anatomical dead space is that portion of the airways (bronchi, trachea, larynx, pharynx, and nasal cavity) which conducts gas to the alveoli. No gas exchange is possible in these spaces.

2

Anesthetic induction

The process by which an animal loses consciousness and enters general anesthesia.

3

Anesthetic maintenance

The process of keeping a Pt in a state of general anesthesia. The period between induction and recovery.

4

Anesthetic protocol

A list of the anesthetic agents and adjuncts prescribed for a particular Pt including doses, routes and order of administration.

5

Anesthetic recovery

The period between the time the anesthetic is discontinued and the time the animal is able to stand and walk without assistance.

6

Central nervous system (CNS) vital centers

Areas of the brain that control cardiovascular function, respiratory function, and thermoregulation.

7

Hypostatic congestion

Pooling of blood in the dependent lung and tissues (those nearest the floor or table).

8

Laryngospasm

A reflexive closure of the glottis in response to contact with any object or substance.

9

Mechanical dead space

Mechanical dead space is that portion of the airways (Y-piece of the breathing circuit, where there is bidirectional flow of gases, and the portion of the ET tube extending beyond the nose or the Y-piece and face mask) which conducts gas to the alveoli. No gas exchange is possible in these spaces.

10

Pneumomediastinum

The presence of air in the space between the lungs that contains the heart and great vessels.

11

Pneumothorax

The presence of air in the space between the lungs and the chest wall (pleural space) associated with collapse of the lungs.

12

Stridor

Noisy breathing caused by turbulent air flow in the upper airways.

13

Titration

Administration of an anesthetic agent in small increments until the desired depth of anesthesia is reached, as opposed to administration of the entire calculated dose.

14

Total intravenous anesthesia

Induction and maintenance of anesthesia by IV injection of ultra-short-acting anesthetics with no concurrent use of inhalant agents. Accomplished using repeat bolus injections or a constant rate infusion (CRI).
