Dog Oxygen Flow Rate Calculator

Dog’s Weight (kg):

Breathing System:

Here’s a comprehensive table summarizing the key information about oxygen flow rates for dogs:

Oxygen Delivery Method	Flow Rate	FiO2 (Fraction of Inspired Oxygen)	Notes
High-Flow Nasal Cannula (HFNC)	1-2 L/kg/min	21-100%	– Start at 1 L/kg/min for 30 min, then increase if needed
	20-30 L/min	Up to 100%	– Significantly improves PaO2 compared to conventional therapy
Conventional Oxygen Therapy	Up to 15 L/min	Varies	– May be insufficient for high respiratory demands
Nasal Cannula	Up to 5 L/min per cannula	30-60%	– Risk of nasal irritation and drying
Face Mask	1-6 L/min	35-45%	– Not suitable for long-term use due to patient intolerance
Oxygen Cage	N/A	50-60%	– Suitable for small dogs, risk of hyperthermia
Flow-by Oxygen	Varies	Varies	– Easiest method in emergencies

Key Points:

High-flow oxygen therapy can deliver higher flow rates and oxygen concentrations than conventional methods .
Flow rates should be tailored to the individual dog’s size and respiratory needs.
Higher flow rates allow for better oxygenation through mechanisms like dead-space washout.
Conventional oxygen therapy may be insufficient for dogs with high respiratory demands.
The choice of delivery method depends on factors like the dog’s size, tolerance, and severity of respiratory distress.

Always consult with a veterinarian to determine the appropriate oxygen therapy and flow rate for a specific dog’s condition.
