Ch 9 Flashcards
Anatomic dead space
Dead space
anesthetic induction
The process by which an animal loses consciousness and enters general anesthesia
Anesthetic maintenance
The process of keeping a patient in a state of general anesthesia. the period between induction and recovery
anesthetic protocol
A list of the anesthetic agents and adjuncts prescribed for a particular patient including doses, routes, and order of administration.
anesthetic recovery
the period between the time and 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.
hypostatic congestion
Pooling of blood in the dependent lung and tissues (those nearest the floor or table).
laryngospasm
A reflexive closure of the glottis in response to contact with any object or substance
mechanical dead space
Dead space -the breathing passages and tubes that convey fresh O2 from the source (the atmosphere or the breathing circuit) to the alveoli, but in which no gas exchange can occur. Anatomic dead space includes the bronchi, trachea, larynx, pharynx, and nasal cavity. Mechanical dead space includes the Y piece of the breathing circuit, where there is bidirectional flow of gases, and the portion of the endotracheal tube extending beyond the nose or the Y-piece and face mask.
pneumomediastinum
pneumomediastinum
The presence of air in the space between the lungs and the chest wall (pleural space) associated with collapse of the lung.
pneumothorax
The presence of air in the space between the lungs and the chest wall (pleural space) associated with collapse of the lung.
stridor
Noisy breathing caused by turbulent air flow in the upper airways.
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.
Total intravenous anesthesia
Induction and maintenance of anesthesia by intravenous injection of ultra-short-acting anesthetics with no concurrent use of inhalant agents. Accomplished using repeat bolus injection or a constant rate infusion.
