Lab Practical Review Flashcards
Anesthetic Drug Dose Calculation:
Weight in kg X Drug Dose (mg/kg) = drug dose in mg
Than take your drug dose in mg x drug solution concentration (mg/ml) = Drug calculation in mL which is your final answer
Weight in kg X dose mg/kg = dose in mg X solution concentration mg/mL = Drug calculation in mL
IV Fluid Drip Rates
Fluid Rate (ml/kg/hr) X Weight in kg = Fluid Rate (mL/hr)
Fluid Rate (mL/hr) X hr/60min X Drop Rate (gtt/mL) = Drop Rate per second (gtt/sec)
Drop Rate are usually: 10gtt/mL &/or 60gtt/mL
Finally you will take your Drop Rate per second (gtt/min) X 10 seconds = Drops per 10 seconds (gtt/10sec) & this is your final answer
Rebreathing Oxygen Flow Rate:
3(body weight in kg x 10) = ?ml/min
Non Rebreathing Oxygen Flow Rate:
Body weight in kg x 300 = ?ml/min
Minimum oxygen flow rate:
500ml/min
Respiratory Rate:
12-20 breaths per minute regular smooth breaths
8 bpm is okay in very fit dogs
Heart Rate:
Dogs:
Range: 60-150 bpm
Ideal: 90-120 bpm
Concern/Notify DVM: <80 bpm
Cats:
Range: 120-180 bpm
Ideal: 130-150 bpm
Concern/Notify DVM: <100 bpm
SPO2 / Pulse Oximeter:
Ideal: >95%
Concern/Notify DVM: <95%
Blood Pressure:
Average: 120/80mmHg
Should not drop below 80/40mmHg
MAP: Above 60
Body Temperature
97-100 F
Add external heat sources until body temp is at least 98F
Body temps 95F or lower can lead to heart contractility issues
CO2 / End Tidal
Range: 35-50 mmHg
Normal/Awake: 35-45 mmHg
Concern: Above 60 mmHg
Etank: Small Emergency Tank
Equation:
PSI x 0.3
Example: If the tank has a 750 PSI and is an E tank with a 20kg dog how would you solve:
750x0.3=225L remaining in the tank
You must turn the Liters to Milliliters: 225L x 1000mL = 225,000ml remaining in the tank
3(20kg x 10) = 600ml/min Oxygen Flow Rate
225,000ml divided by 600 ml/min = 375 minutes is how long the tank will last with this oxygen flow rate
