Physical Exam & Behavior Flashcards
Normal Temp for Cats/Dogs
100.5 F to 102.5 F
Hyperthermia
104 F and higher
Causes of Hyperthermia
- Diseases
- Neurological injury (stroke)
- Heat Stroke
- Drug toxicity
Hyperthermia Results in
- Increased tissue O2 reqs
- Vasodilation to release body heat
- Cardiac workload increases
- Damage to vascular cells leading to DIC
- Bounding pulse, tachycardia, & pale gums (slow refill)
Interventions for Hyperthermia
- Cool compress
- Cool w/ fan
- Temperate bath
- Room temp IV fluids
- Cool water enemas
Don’t use for Hyperthermia
Ice water, it can cause vasoconstriction which will trap heat in the body, don’t want to cool down too fast
Hypothermia
99 F or less
Causes of Hypothermia
- Medication (anesthesia)
- Age (less than 1 month old)
- Environment (left in snow)
Hypothermia results in
- reduced metabolic rate
- decreased O2 consumption (slower breathing)
- decreased ability of hemoglobin to release O2 to tissue
- peripheral vasconstriction
- decreased heart rate
- hypotension (low blood pressure)
- decreased GI motility
Interventions for Hypothermia
- warm blankets
- warm water bottles/gloves
- warm IV fluids
- heat lamps (watch animal closely)
- circulating water blanket
Don’t use for Hypothermia
- heating pads
- stationary heating elements
(get too hot and can cause burns)
Pulse
A palpable rhythmic expansion of an artery due to contraction of the heart
Normal pulse for adult dogs
60-160 bpm
Normal pulse for Toy breeds
60-180 bpm
Normal pulse for puppies
up to 220 bpm
Normal pulse for cats
110-220 bpm (not unusual to be higher at the vet, cat’s stressed)
Where/how is the pulse taken
The usual site is at the femoral artery, count for 15 secs and times by 4 to get bpm (beats per minute)
Thready Pulse
weak pulse that can be a sign of shock of cardiopulmonary dz
Bounding Pulse
overly strong pulse that can be a sign of stress, pain, or cardiopulmonary dz
Bradycardia
Slow heart rate; decrease in cardiac output can cause organ failure or death
Causes of Bradycardia
- hypothermia
- metabolic diseases
- medications
- hypothroidism
Interventions for Bradycardia
- ECG
- Thoracic Radiograph for Dx
- Supplement w/ O2
- Chemical (atropine or epinephrine)
Tachycardia
Fast heart rate; can lead to permanent heart arrhythmia, murmurs, or cardiac failure
Causes of Tachycardia
- pain
- shock
- stress
- excitement
- febrile (fever)
- medications
Interventions for Tachycardia
- find the underlying cause
- treat the cause appropriately
How is respiration measured?
Watch the chest for expansion & contraction for 15 sec x by 4 for rpm (respirations per minute)
Do first for TPR
Normal Resp Rate for Cats:
20-30 rpm
Normal Resp Rate for Dogs:
15-30 rpm
How is panting recorded?
Considered normal in dogs, note if labor
Not normal in cats
Tachypnea
Rapid, shallow breathing
Causes of Tachypnea
- obstruction
- pain
- stress
- pulmonary dz
- hyperthermia
- shock
- seen in animals w/ pneumothorax/hemothorax
Interventions for Tachypnea
- minimize/decrease stress
- administer O2
- treat shock
- cool temp
If there is an obstruction in the upper airway:
- palpate for object
- radiographs to locate if not palpable
- might need to sedate
- remove obstruction
Dyspnea
Difficulty breathing
Causes of Dyspnea
- restricted airway
- pneumothorax
- pleural effusion
- upper airway dz (laryngeal paralysis/obstruction)
- lower airway dz (bronchitis, kennel cough)
- diaphragmatic hernia
- CHF (congestive heart failure)
- obesity
- pulmonary dz
Interventions for Dyspnea
- administer O2
- IVF
- Chest radiographs
Weight should be taken daily because:
it’s important for medication calculations & hydration state
