PATHOLOGICAL BASIS OF DISEASE Flashcards
These are clinical measurements comprising pulse rate, respiratory rate, rectal temperature.
Vital signs
Enumerate the vital signs of animals.
- Pulse rate
- Respiratory rate
- Rectal temp. (PRT)
Define pulse rate.
Rate of arterial pulse synonymous to heart eate
Define respiratory rate.
Rate of lung breaths; one cycle of respiration (inspiration and expiration)
What is the normal pulse rate of a dog?
100-130 bpm
What is the normal pulse rate of a cat?
110-140 bpm
What is the normal pulse rate of rabbit?
180-350 bpm
Define tachycardia and give the circumstances that trigger it.
- Increased heart rate
- Nervousness
- Hyperthyroidism
- Hyperactivity
- Heat
- Exhaustion
- Fever
Define bradycardia and give the circumstances that trigger it.
- Decreased heart rate
- Sleeping
- Rest
- Cold condition
What is the normal respiratory rate of dog?
22 breaths/min (+/- 5); 17-27 breaths/min
What is the normal respiratory rate of cat?
26 breaths/min (+/-5); 21-21-31 breaths/min
What is the normal respiratory rate of rabbit?
39 breaths/min (+/-5) = 34-44 breaths/min
Define tachypnea and give circumstances that trigger it.
- Increased respiratory rate
- Hyperactivity
- Increased environmental temp.
Define bradypnea and give circumstances that trigger it.
- Slow respiratory rate
- Rest
What is the normal rectal temp. of dog?
38.5 - 39.5 C (38.9)
What is the normal rectal temp. of dog?
38.0 - 39.0 C (38.6 C)
What is the normal rectal temp. of rabbit?
38.0 - 39.9 C (39.0 C)
Define hyperthermia and give circumstances that trigger it.
- High rectal temp.
- Fever
- Increased BMR (too much production of T3 and T4)
- Hyperthyroidism
Define hypothermia and give circumstances that trigger it.
- Low rectal temp.
- Decreased environmental temp.
- Sign of impending death among animal patients
This is defined as elevation in body temp. above normal for an extended period of time; established from lesion and an indicator that there is an infection.
Pyrexia of fever
Why do we get a fever if there’s an infection?
Gram negative is ingested by a macrophage upon ingestion > macrophage will release interleukin 1 > will circulate throughout the body > go to hypothalamus (main terminal organ of the body and control center) > is stimulated to release prostaglandin > resets the body’s thermostat to increase body temp
Psychrophiles thrive at what temperature ?
0 - 15 C
Mesophiles thrive at what temperature ?
15 - 40 C (most common microorganism)
Bacillus and Clostridium is a spore-forming bacteria resistant to heat that can be killed with ____ C in a span of ____ minutes.
95 C; 120 minutes
