Flashcards in Chpt. 8 - Key Terms Deck (14):
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.
The process by which an animal loses consciousness and enters general anesthesia.
The process of keeping a Pt in a state of general anesthesia. The period between induction and recovery.
A list of the anesthetic agents and adjuncts prescribed for a particular Pt including doses, routes and order of administration.
The period between the time the anesthetic is discontinued and the time the animal is able to stand and walk without assistance.
Central nervous system (CNS) vital centers
Areas of the brain that control cardiovascular function, respiratory function, and thermoregulation.
Pooling of blood in the dependent lung and tissues (those nearest the floor or table).
A reflexive closure of the glottis in response to contact with any object or substance.
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.
The presence of air in the space between the lungs that contains the heart and great vessels.
The presence of air in the space between the lungs and the chest wall (pleural space) associated with collapse of the lungs.
Noisy breathing caused by turbulent air flow in the upper airways.
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.
