The Disadvantages of Nasal Cannula

If you have a heart or lung condition, you may require a nasal cannula---an apparatus designed to supplement respiratory function. While your cannula can boost your breathing capacity by increasing the flow of oxygen into your bloodstream, it also comes with specific risks and disadvantages. To ensure your safety and convenience when using one of these devices, educate yourself on the potential pitfalls of the nasal cannula.

Safety Concerns

• According to WebMD, compressed air of any kind can create a fire hazard. Those with a nasal cannula should avoid flames of any kind---including smoking or being around those who are smoking---and should keep the tank at least six feet away from heat sources.

  Oxygen tanks can sustain damage, and possibly rupture, if they tip over; those with nasal cannulas need to take special care to keep the tank standing on end.

Discomfort

• The breathing tubes attached to your nasal cannula can cause a great deal of discomfort and possibly pain. The constant flow of air can cause dryness and cracked skin on your lips and inside your nostrils. WebMD recommends applying a water-based moisturizer to these areas. (Moisturizers with petroleum as a base can block the flow of air from the tubes.)

  Placing the tubes behind your ears can also cause discomfort over time, says WebMD, which recommends padding the tubing with gauze to prevent soreness.

Inconvenience

• According to the Cleveland Clinic, only qualified technicians can fill and refill the tank of nasal cannula, requiring that the tank's owner to remain home for regular fill-ups. The air inside the tank can also evaporate, which also necessitates regular filling.

Regular Maintenance

• According to WebMD, nasal cannulas require constant maintenance. The site recommends washing the parts of the tubes that enter the nose up to twice a week. WebMD also recommends replacing these parts biweekly or monthly, requiring additional cost.
