Anesthetic Machines Flashcards
Why does tidal volume decrease during anesthesia
The drugs are depressing the respiratory system
If the scavenger is completely open, what is the path of least resistance
Scavenger
What is the primary function of an anesthetic machine
to deliver the anesthetic by vaporizing the liquid drug and delivering it to the patient
During anesthesia _____________ _______________ is decreased due to respiratory depression
Tidal volume
Supplementation with 100% oxygen can increase ________________ requirement
Metabolic
Anesthetic machines remove (scavenger) and recirculate exhaled air/ waste gas, eliminating ___________
CO2
How would an anesthetic machine recirculate waste gas/ exhaled air
Closed pop off/ system valve causing it to go through the CO2 absorber
CO2 absorber crystals last a long time when you’re running an open system (open pop off valve) bc…
Exhalation then goes to the scavenger system
E cylinder O2 tanks are always…

What is the significance of the pin index system
To stop you from putting the wrong gas on the wrong line
