What sizes do cannulas come in?
According to a 2015 study, the most common sizes range from 14 to 22 gauge. The higher the gauge number, the smaller the cannula. Different sized cannulas move liquid through them at different rates, known as flow rates.
What is Salter nasal cannula?
The Salter Labs 16soft Nasal Cannulas are soft and flexible tubes that are used to provide supplemental oxygen to an adult patient with respiratory or breathing disorders.
What are the different types of oxygen cannulas?
The Three Different Types Of Cannulas
- Intravenous Cannula.
- Nasal Cannula (Oral nasal cannula)
- Microcannula.
How does high-flow nasal cannula work?
By creating a positive pressure environment, high-flow nasal cannula presses from the interior of the nasopharynx outwards. This dilates the radius of the nasopharyngeal airways and dramatically reduces the resistance to airway flow, thus increasing ventilation and oxygenation potential.
What are the sizes of oxygen cannula?
A Variety Of Sizes Ensures the Perfect Fit For Your Patients
| Cannula Sizes | Cannula Flow Range |
|---|---|
| Pediatric Small | 1-20 L/min |
| Pediatric / Adult Small | 5-40 L/min |
| Adult | 5-40 L/min |
| Adult Large | 5-40 L/min |
Are all nasal cannulas the same?
There are two types of nasal cannulas: low flow and high flow. The device has two prongs and sits below the nose. The two prongs deliver oxygen directly into your nostrils.
What size is oxygen tubing?

Every 2–4 weeks, replace your cannula or mask. Change every time you get sick. Every month, replace your air filter. Every 2 months, replace your tubing.
Which cannula is used for adults?
Peripheral IV cannula: The most commonly used IV cannula, the peripheral IV cannula is usually used for emergency room and surgical patients, or for those individuals who undergo radiological imaging. Each of these IV lines is used for up to four days and not beyond that.
Is 2 liters of oxygen a lot for Covid?
Admitted to the COVID-19 floor Some patients only need 1 to 10 liters per minute of supplemental oxygen. But others we have to put on “high flow” oxygen system – 30 liters to 70 liters per minute. That’s a lot. It can be very uncomfortable as air will be blown up your nose at a very rapid rate.
What is the maximum nasal cannula flow rate?
Flow rates of 1-4 litres per minute are used with nasal cannulas, equating to a concentration of approximately 24-40% oxygen. Flow rates of up to 6 litres can be given but this will often cause nasal dryness and can be uncomfortable for patients (British Thoracic Society, 2008).
