Homework 2 Flashcards
An Anesthesia machine must be able to…
- deliver O2 at a controlled rate for anesthesia or CPR
- mix Anesthetic gas and O2 and deliver that mixture to the patient
- remove exhaled gases through a scavenging system or safely recirculate them.
“E” tanks containing compressed oxygen…
when full have a pressure reading of 2200 psi
This structure on the anesthetic machine decreases the oxygen pressure to 40-50 psi.
Pressure-Reducing Valve
This structure on the anesthetic machine decreases the oxygen pressure to 15 psi.
Oxygen Flow Meter
Most Precision Vaporizers are temperature, carrier gas flow and back pressure compensated, in addition they…
- are used with high-vapor pressure anesthetic agents
- are always found outside the “circle” system
- are calibrated to store a specific liquid anesthetic agent.
What size reservoir bag would be needed for a 30 kg dog?
c. 2.0 Liter
Multiple terms are used for manual ventilation (bagging, assisted ventilation, artificial ventilation). When delivering a manual ventilation which is / are true?
- The “pop off” valve is closed
- The maximum pressure to deliver is 20 cm H2O
- To mimic normal respiration, give longer inspiration with quick expiration.
These scissors are used for delicate surgical dissection. The blades are thin, delicate and about 1/4th the overall length of the instrument.
Metzenbaum Scissors
These hemostats have horizontal serration that only extend ½ the length of the jaw.
Kelly Hemostats
These Needle Holders have scissor guild into the jaws.
Olsen-Hegar
These Thumb Tissue Forceps have two parallel rows of nine shallow teeth on both tips and a common surgery tissue forceps.
Adson-Brown
These Handheld Retractors are double- ended with a narrow blunt blade end and a toothed, traumatic end.
Senn
These Forceps that are designed to handle intestinal tissue delicately are atraumatic.
Babcock
This orthopedic surgery instrument has cupped tips with sharp edges. It has squeeze handles. It is used to break up bits and pieces of bone or remove pieces of unnecessary bone
Bone Rongeurs
Bone Plates….
- can have different shapes or be bent to conform to the shape needed
- have width numbers that indicate the screw size needed to secure the plate.
- have lengths defined by the number of holes available to be filled with screws
Which of the following is NOT an ophthalmic surgery instrument
Groove Director
This absorbable monofilament suture material has good relative knot security, mild tissue reactivity, maintains up to 69% tensile strength at 42 days post-surgery and is completely absorbed in 180 days.
PDS
What is the purpose of the “Murphy Eye” of an Endotracheal Tube?
It helps prevent asphyxiation in the event that the beveled end opening in the trachea is blocked with mucous or other substance.
What is NOT a true statement of a supraglottic airway device (SAD)?
It has a blade and light source which allows for depressing the tongue and better visualization of the throat.
Which of the following are true for the use of anesthetic masks and chambers?
- Neither maintain an open airway.
- Neither protects against pulmonary aspiration
- Neither allow for manual ventilation of the patient.
A three hole system containing one outlet port and a specific two pin index safety system holes is found for which piece of anesthetic machine equipment?
E oxygen tank
This anesthesia machine structure delivers pure oxygen at a rate of 35 to 75 Liters per minute when used. What is this structure?
oxygen flush valve
Immediately after administering a manual ventilation (with a partial-rebreathing (semi closed) system the anesthetist…
opens the “pop-off” valve
The Carbon Dioxide absorber granules…
are exhausted when the color of the granules are tan
Which of the following is an example of a non-rebreathing anesthetic system?
Modified Mapleson A system
Bain Coaxial System
Ayre’s T piece system
How frequently should a test for low – pressure leaks on an anesthetic system be performed?
Before each use
After injectable anesthetic induction, continued gas anesthetic induction is usually necessary to have the patient achieve maintenance anesthesia. Which of the following
anesthetic gas induction protocols is best for a 30 kg patient on a partial rebreathing system (semi-closed)?
Isoflurane at 3% and Oxygen Flow rate at 3 Liters per minute
Active Scavenging…
is a mechanical device using a vacuum to remove gases
Best at conserving heat and moisture
Passive Scavenging
works best if restricted to a room vent on an outside wall.
Activated Charcoal Canister
Should be suspended above the floor so air can circulate through the vents.
Total Rebreathing (Closed)
Best at conserving heat and moisture
Partial Rebreathing (Semi-Closed)
The usual Oxygen flow rate for maintenance anesthesia is calculated at
20 – 40 ml / kg / min.
Non-Rebreathing (Semi-Open/Open)
Generally recommended for patients weighing less than 7 kg
Does not usually contain a CO2 absorber canister, pressure manometer and unidirectional valves.
What is this part of the anesthesia machine that is calibrated in liters per minute or milliliters per minute?
Oxygen Flow Meter
What is this part of the anesthesia machine that is calibrated in percentage of total anesthetic gas exiting?
Out of Circuit (Circle) Precision Vaporizer
What is this part of the anesthesia machine that indicates the pressure of the gases within the breathing circuit (circle). This pressure is also represented by the pressure in the patient airways and lungs.
Pressure Manometer
