Pulse oximeters are essential tools in veterinary medicine, but getting an accurate SpO₂ (oxygen saturation) reading can be tricky. Here are key tips to ensure reliable results:
✅ Choose the Right Placement
Use areas with good blood flow: tongue, ear pinna, lip, vulva, prepuce, or interdigital webbing in small animals.
In large animals, try nasal mucosa or rectal probes for better contact.
✅ Minimize Motion
Patient movement can cause artifacts. Try restraining gently or using a clip designed to hold the probe securely.
✅ Ensure Good Contact
The probe should be snug but not too tight to avoid restricting blood flow.
✅ Check Perfusion & Temperature
Hypothermia or poor perfusion (e.g., hypotension) can lead to weak signals. Warm the patient if needed.
✅ Reduce Ambient Light Interference
Bright surgical lights can interfere with readings. Cover the probe if necessary.
✅ Confirm with Clinical Signs
Always correlate SpO₂ readings with mucous membrane color, capillary refill time, and respiratory rate to ensure accuracy.
Using these techniques, you’ll get more consistent and reliable oxygen saturation readings, leading to better patient care! 🐶🐱🐴
