unsafe pressure for small animals

over 20 cmH2O

pure oxygen to patient from the oxygen flush valve

45-50psi

volume of air inspired or expired in a single breath

tidal volume

respiratory rate less than____ breaths per minute should be reported

6-8

what ET tube as an eye at the end?

murphy

normal respiratory rate for dog under anesthesia

8-20 per minute

rubber ET tubes may

crack

non-rebreathing system requires higher oxygen than rebreathing system

true

carbon dioxide absorber is used only with the rebreathing system

true

closed rebreathing anesthetic systems have a lower flow rate than semiclosed rebreathing or nonrebreathing systems

true

which vaporizer is most common?

precision

nonrebreathing systems should have maintenance flow rates that are

very high at least 200ml/kg.min

minimum size for reservoir bag

50-60ml/kg

what sets the pace of the heart?

sinoatrial node

what chemical substances produced by the body contributes to intense pain associated with inflammation?

prostaglandins, histamine and proteolytic enzymes

why is pain more vague in the throacic and visceral areas?

few sensory nerves

what re the most commonly usede analgesics for postop pain?

narcotics

what are predominately used for mild-to-moderate chronic musculoskeletal pain?

NSAIDS

opioids have analgesic effects because

ineteract with specific opioid receptors in brain and spinal cord

NSAIDS have analgesic effects because

inhibition of cyclooxygenase

increased response to a stimulus that is normally painful

hyperalgesia

production of pain due to a stimulus that dose not normally provoke pain

allodynia

kappa and mu are?

types of opioid receptors in the CNS

what is one drug that has no analgesic effects?

diazepam/valium

which opioid receptor provides the most pain relief?

Mu

absence of pain in the presence of stimuli that would normally be painful

analgesia

common side effects of narcotics in dogs

panting, respiratory depression and bradycardia

respiratory rate and adequacy of ventilation measured with

capnometer

oxygen flow rate at beginning

3L/min

atelectasis

collapsed or airless state of the lung

acepromazine

phenothiazine tranquilizer

atropine

anticholinergic

butorphanol

opioid

diazepam

benzodiazapine

etomidate

class by itself

fentanyl

opioid

glycopyrrolate

anticholinergic

ketamine

dissociative

dexedetomidine

alpha 2 agonist

methohexital

barbiturate

midazolam

benzodiazepine

morphine

opioid

propofol

class by itself

tletamine

alpha 2 agonist

thiopental

barbiturate

ketamine provides

some pain relief

state of calm taht patient is reluctant to move and is aware of but unconcerned of surroundings

tranquilization

patient that is moderately dehydrated or anemic is at a

class 3 anesthetic risk

atropine

anticholinergic

atropine

increases heart rate

atropine

causes mydriasis

CO2/sodasorb should be changed

every 8-10 hours

signs of CO2 absorber not working

tachypnea, tachycardia, brick red mm, cardiac arrhythmias
