What is a disadvantage of using an anesthetic chamber for induction?
Cannot monitor patient closely, takes longer, requires a high flow rate
Size E Gas Supply Cylinders have an oxygen capacity of about ____ L, and a pressure of about _____ psi
660, 2100
The pressure-reducing valve controls the gas pressure to a safe _________ psi (range)
40-50
The Line Pressure Gauge indicates the pressure in the gas line between the pressure-reducing valve and flowmeter and should read _______ psi after the tank is opened and ______ psi when the tank is closed and flushed.
40-50, 0
Line pressure drops to _____ psi across the flowmeter
15
When reading the flowmeter, be sure to measure at the _____ of the ball (top, middle or bottom)
middle
The Oxygen Flush Valve delivers a short, large burst of pure oxygen directly into rebreathing circuit or common gas outlet, measuring ________ L/min
15-50
Rebreathing circuits are useful in animals that are susceptible to _____
hypothermia since the gas is warmer
We often use a Semi-Closed rebreathing system but in large animals due to their size we use ________ rebreathing systems
closed
The ideal breathing bag will hold at least _______ml/kg of patient body weight
60
During manual ventilation (bagging) you are forcing fresh gas into the alveoli to normalize gas exchange, this should be done every ______ minutes
5-10
What is the primary absorbent ingredient of Soda Lime?
Calcium hydroxide
Using depleted Soda Lime granules will result in _______ being inhaled by the patient
Carbon Dioxide
The pressure manometer indicates the pressure of gases within the breathing circuit while manual ventilating, which should not exceed _____cm of H2O or else it could cause _____, _____ or _______
15, Dyspnea, Lung damage, Pneumothorax
What is the negative pressure relief valve also referred to as?
Air Intake Valve
What does the Negative Pressure Relief Valve do?
Admits room air into circuit if negative pressure is detected in the circuit
Negative pressure in the circuit is indicated by a ________
collapsed reservoir bag
What are 4 ways in which Negative Pressure can build up in the circuit?
Machine is not correctly assembled, scavenging system is exerting excessive suction, oxygen flow rate is too low, or tank is out of oxygen
In a ________ circuit (type of F circuit) the inner tube is inspiratory and the outer tube is expiratory
Co-axial
What is the flow rate range for induction via Chamber?
5L/minute
What is the flow rate range for induction via Mask?

What is the flow rate range for induction via IV or ET? (rebreathing)
50-200ml/kg/min
What is the flow rate range for Bain circuits?
130-200ml/kg/min
