Prior to hooking the feline up to oxygen gas, the veterinarian will review the cat’s medical history and conduct a physical exam. Further routine diagnostic tests may be conducted after oxygen therapy has begun and the cat is stabilized.
Note that oxygen therapy can is a monitored procedure and, like other stabilizer therapies, can be delivered at a high or low rate. The calculations of rate of administration are to be determined by the veterinarian.
Below is a summary of each of the most commonly used oxygen therapy methods:
Nasal Cannula
A fast and easy technique that involves the placement of a human cannula. A nasal cannula is often placed when it is anticipated that the feline will be moved for diagnostic tests. In order to keep the two small prongs from slipping out of the nose, a nose band is creating using adhesive tape and skin staples. The Y section of the tubing will then be tightened behind the cat’s head.
Nasal Catheter
Sedation is required to place a nasal catheter, which the veterinarian will select based on the feline’s health. A few drops of proparacaine will be placed into the nostril to numb the area and a suture will be placed at the base of the nostril, which will serve as an anchor later on. A feeding-tube is selected (size and style considered) and lubricated with a water-soluble jelly. The length of the tube is pre-measured from the outside, along the cat’s face before inserting the tube into the nasal cavity. Once the tube is in proper place, the premade suture at the base of the cat’s nostril will be used to tie the tube and secure it. Tape will be placed around the cat’s neck to anchor the loose tube and the end of that tube will be attached to oxygen.
Oxygen Mask
Oxygen therapy can be delivered through the use of an oxygen mask, specially designed for felines and commonly used during anesthesia. The correct sized mask is found and secured in place with either tape, or a feline muzzle. The mask is then attached to oxygen gas.
Crowe Oxygen Collar
An Elizabethan collar (one size larger than generally used for a cat) is secured around the cat’s neck and an oxygen tube is allowed underneath the collar from below. Tape is then used to secure the collar is place. Plastic wrap is then laid over the face of the Elizabethan collar, covering 50-80% of the surface area.
Oxygen Cage/Chamber
A noninvasive form of oxygen therapy, filling a small space with oxygen to allow the feline to breathe in.
