Inhalational Induction Flashcards
1
Q
8 factors for Faster Inhalational Induction
A
- Rapid buildup of agent in the alveoli
- low blood solubility of the agent
- higher percentage on the vaporizer dial
- higher fresh gas flows
- smaller anesthesia circuit volume
- low cardiac output
- higher minute ventilation
- low functional residual capacity (FRC)
2
Q
8 factors for Slower Inhalational Induction
A
- slower build up of agent in the alveoli
- higher blood solubility of the agent
- lower percentage on the vaporizer dial
- lower fresh gas flows
- larger circuit volume
- high cardiac output
- lower minute ventilation
- high functional residual capacity (FRC)
3
Q
Factors that delay emergence from inhalational anesthetics (13)
A
- older pts (geriatric pts)
- obese pts
- long operation times
- operations where higher concentrations of agent were used
- low fresh gas flows during emergence
- high blood solubility of the volatile agent
- lower minute ventilation
- higher doses of narcotics
- closed APL valve
- higher functional residual capacity (FRC)
- lung disease (decreased alveolar capillary diffusion)
- low cardiac output
- hypothermia
4
Q
3 things that happen from low cardiac output
A
- faster build up of agent concentration in the blood
- faster buildup of agent concentration in the lungs
- faster inhalational induction
5
Q
Advantages of low fresh gas flow
A
- cost effective
- preserves tracheal heat and moisture
- slows the drying process of soda lime CO2 granules
- better preserves the pt’s body temperature
6
Q
disadvantages of low fresh gas flow
A
- slower inhalational induction
2. slower emergence from anesthesia
7
Q
Disadvantages of high fresh gas flow
A
- expensive
- dries out the pt’s airway
- accelerates the drying out of the soda lime CO2 granules
8
Q
