Anesthetized patients encounter respiratory depression from anesthetic drugs, so we supplement their oxygen to avoid hypoxemia. What is considered the minimum FIO2?
Minimum FIO2 = 35%
T/F: It is fine to use the quick flush valve on a small patient attached to a low volume breathing system because you're a badass and you play by your own rules
No. It's not.
You would pop your patient.
...wouldn't be very badass then.
What are the two main functions of any patient breathing system (PBS)?
Deliver oxygen +/- anesthetic gas
- Eliminate carbon dioxide
- Eliminate carbon dioxide
According to the ACVA, how often should you record findings while an animal is under anesthesia?
Every 5-10 minutes
__________ bypasses the vaporizer and delivers O2 directly to the patient breathing circuit
What flow rate is typically used with a non-rebreathing system?
Throughout the entire procedure
What is the equation you use to calculate proper size of rebreathing bag?
Body weight x Tidal volume x 5
- Normal tidal volume = 10-20 mls/kg
The pressure reduction valve reduces cylinder pressure to a fixed _____ psi
Provides a constant pressure of 50 psi to the flowmeter
What is the main function of the 'pop-off' valve?
limits pressure buildup within the circuit
ALWAYS keep open unless delivering manual, controlled, or assisted ventilation
Loss of sensitivity to pain is termed:
At what temperature (Farenheit) do we consider the patient hypothermic?
96oF or less
Below 94oF anesthetic requirements are reduced, recovery may be prolonged, CV function depressed
How do you calculate remaining oxygen within an 'E' Cylinder?
A state characterized by CNS depression accompanied by drowsiness is termed:
What is the mechanism of action for Atropine?
Competitively inhibits acetylcholine (and other cholinergic stimulators) at the postganglionic parasympathetic neuroeffector site
In order to avoid hypoxemia, N2O:O2 should not exceed a ratio of ____
What monitoring adjunct assesses the effects of anesthesia drugs on synaptic activity?
A drug induced state of deep sleep from which a patient cannot be easily aroused:
Is this an example of a VOC or VIC?
Vaporizer Out of Circuit. These are precision vaporizers.
What is the SVP for Desflurane at 20oC?
T/F: Manual palpation of pulse provides an objective measure of adequacy of cardiac output and tissue perfusion
Manual palpation of pulse provides a subjective measure of adequacy of cardiac output and tissue perfusion
How many liters of oxygen can fit in an E Cylinder?
What is the reversal agent for dexmedetomidine?
What is the SVP for Sevoflurane at 20oC?
In an anesthesia machine, what flow meter is always last in the series?
Oxygen Flow Meter
At what pressure should E and H Cylinders be changed?
T/F: Pin Index Safety System is used for E cylinders only
The purpose of the PISS is to avoid improper cylinder connection (i.e. oxygen mismatch)
T/F: If no compensating mechanism is present, altitude can have an effect on output concentration of the anesthetic vaporizer
T/F: There is an inverse relationship between temperature and saturated vapor pressure (SVP)
There is a direct relationship between temperature and saturated vapor pressure (SVP). As temperature increases, SVP increases.
As temperature increases, saturated vapor pressure (SVP) __________
At what stage of anesthesia are vomiting and swallowing reflexes lost?
Stage III (Surgical Anesthesia)
