Find the Right Oxygen Support for Your Pet
How do I choose between S and M mask?
Measure your pet’s nose area before ordering. Choose S for smaller noses and shorter muzzles, and choose M for wider or longer snouts.
Can VL-2 connect to the oxygen chamber?
VL-2 mask bundles are designed for oxygen mask use. For chamber oxygen care, choose VH-3 or Serene 5 home bundles.
Is the 100L chamber suitable for large dogs?
The 100L chamber is best for cats, small dogs, and small-to-medium pets. It is not recommended for large dogs.
Where should I place the machine and chamber?
Place the machine on a stable surface near the chamber, connect the tubing securely, and keep your pet comfortable and supervised during use.
