Flashcards in Chpt. 12 - Tech Notes Deck (7):
1

Human error is one of the most common reasons for anesthetic emergencies.
Examples include the following:

- Improper calculations
- Lack of attention to the anesthetic machine
- Lack of proper patient evaluation
- Incorrect use of drugs - for example, administering a drug by the incorrect route
- Lack of knowledge of drug pharmacology

2

What can happen if the pop-off valve is closed and the oxygen flow rate is greater than the patient's oxygen requirement?

Pressure within the circuit and the patient's lungs and thoracic cavity will rapidly rise.
This prevents exhalation and decreases the venous return to the heart, which decreases cardiac output and can lead to death within a short time unless recognized and corrected immediately.

3

What kind of protocols are generally safer?

Multidrug protocols are generally safer than use of only one or two drugs.

4

What type of dog poses special problems for the anesthetist?

Brachycephalic dogs

6

What is the most common cardiovascular problem seen by the veterinary anesthetist?
