Anesthesia
time when a patient is being given anesthesia to make it sleep and remain unconscious and free of sensation during surgery
induction phase
process of removing an endotracheal tube from a patient
extubation
monitor is placed onto a patient through metal leads called electrodes that measure the electrical activity of the heart
electrocardiogram (ECG or EKG)
converts liquid anesthesia into a gaseous form, which the patient inhales
vaporizer
a collapsible reservoir from which gases are inhaled and into which gases may be exhaled during general anesthesia or artificial ventilation.
rebreathing bag
process of placing a tube into the trachea to establish an airway and allow the patient to continue to inhale gases that keep it under general anesthesia as long as necessary
Intubation
device used to measure an animal’s blood pressure during surgery; also helps determine tissue perfusion as well as depth of anesthesia; also called a blood pressure monitor
sphygmomanometer
This is the excitement phase when a patient displays involuntary movements and vocalizations.
Plane II
metal container that holds compressed forms of gas to keep patients oxygenated and breathing during anesthesia
amount of oxygen required by a patient
tidal volume
level of awareness of a patient under anesthesia
plane
device used to measure a patient’s vital signs by indirectly measuring oxygen saturation within the blood and any changes in blood volume
pulse oximeter
an overdose of anesthesia and a deeper level in which the patient could potentially die. No reflexes are noted, vital signs are decreased, and pupils are centrally fixed and dilated.
Plane IV
indicates how much oxygen is left in a tank
pressure valve
used to release excess amounts of gas when the pressure becomes too high within a machine system
pop-off valve
allows evaluation of the eye to determine which plane of anesthesia a patient is in
blink reflex or palpebral reflex
device placed into the esophagus next to the endotracheal tube; emits the sound of the heartbeat
esophageal stethoscope
tool made of heavy metal that has a light source on the end to help light the airway for viewing
laryngoscope
located on the anesthesia machine near the vaporizer; is adjusted for the proper rate of oxygen flow to the patient
flow meter
tube attached to a pop-off valve to prevent gas from leaking into a room; pushes gases outside of the facility to escape to the outside air
scavenger hose
located about three-quarters of the way down the endotracheal tube; inflatable; allows the tube to be inflated with air to create a tight seal around the trachea to prevent any moisture or material from entering the lung field
cuff
light depth of anesthesia. This is the ideal plane for surgery, where vital signs remain normal, pupils are regular in size and rotate medially, and mild to no reflexes are present. Pupils are regular in size and rotate medially, and mild to no reflexes are present.
Plane III
The patient should be placed on a ground plate when utilizing this device
Electrocautery unit
granules within a canister that absorb carbon dioxide
soda lime
thin plastic hose that allows the oxygen and anesthetic gas to flow to the patient by connecting from the machine to the endotracheal tube
corrugated tubing
