Feline/Canine Normal Temp.

100.2-102.2 degrees farenheit

Canine pulse

60-160 bpm

Feline Pulse

140-220 bpm

Canine Respitory Rate

16-32 bpm

Feline Respitory

20-42 bpm

voluntary movement and palpebral reflex

absent in the surgical plane of anasthesia

jaw tone

relaxed but present in the surgical plane of anasthesia

eyes pointed rostral

eye position in the surgical plane of anasthesia

more than 95%

normal pulse ox

35-50

normal EtCO₂

normal capnograph

Cardiogenic Oscillations

Leak

Systolic

Heart contracts

80-150

normal SAP

Diastolic

Heart rests between beats

50-80

normal DAP

hypotension

tx: up fluid rate, lower gas, reverse pre-meds

hypertension

tx: more gas, pain meds, lower fluid rate

40% of pt limb

BP cuff size

anticholinergic: atropine or glycopyrrolate

tx: low HR with hypotension

P wave

atrial depolarization

QRS complex

atrial repolarization and ventricular depolarization

T wave

ventricular repolarization

sinus arrhythmia

low heart rate, then high, then low

Ventricular Premature Complex

wide, bizzare QRS complexes

160

tx with lidocaine bolus when VPC HR exceeds this BPM

1st Degree AV block

PR interval long; signal ultimately reaches the ventricals

2nd degree AV Block

P waves don’t always have a QRS complex; some impulses do not reach the ventricles

3rd degree AV block

P waves and QRS complexes lack association; usually stay bradycardic with atropine
