How many types of nasal cannula are there?
There are two main types of cannula: IV cannulas: IV cannulas consist of short, flexible tubing doctors place into a vein. Nasal cannulas: Nasal cannulas consist of flexible tubing that sits inside the nostrils and delivers oxygen.
What are the different types of oxygen masks?
There are generally three basic styles of oxygen delivery devices based on their design: low-flow, reservoir and high-flow.
What is the difference between Optiflow and high flow?
Nasal high flow oxygen (Optiflow™) is a new alternative as it provides warmed humidified oxygen at high flow, and also has been shown to assist breathing and improve recovery. It is comfortable during use and indeed may be more comfortable than standard (dry) oxygen via a facemask (Hudson type) or nasal prongs.
What are the parts of nasal cannula?
A nasal cannula consists of a flexible tube that is placed under the nose. The tube includes two prongs that go inside the nostrils. A face mask covers the nose and mouth. Both methods of delivery attach to oxygen sources, which come in a variety of sizes.
What are the different types of IV cannula?
There are 3 main types of IV cannulas, namely: peripheral IV Cannula, central line IV cannula and mid-line IV cannula. The central line intravenous cannulas are used for long term treatments, followed by midline cannulas used in less invasive scenarios.
Are all nasal cannulas the same?
Most cannulas come in three basic sizes: adult, pediatric or infant, which can work for the majority of patients. The shape of the nasal prong can also vary from curved to straight and tapered to flare. This is based on patient preference and nose shape.
What are the different oxygen delivery systems?
Oxygen: delivery devices
- Oxygen therapy.
- Nasal cannulae.
- Hudson mask (rarely used)
- Venturi mask.
- Non-rebreather mask.
- Non-invasive ventilation (CPAP/BiPAP): click here for how to start patients on NIV.
- Invasive ventilation.
What is the difference between Optiflow and CPAP?
The Airvo (a NHF system) is a flow-based therapy (you adjust flow rate for your patient), CPAP is a pressure-based therapy, you set a pressure range for your patient. The pressure derived from Optiflow NHF therapy is dynamic, not set and not constant.
Is nasal cannula high or low flow?
High-flow nasal cannula (HFNC) therapy is an oxygen supply system capable of delivering up to 100% humidified and heated oxygen at a flow rate of up to 60 liters per minute.
When is a nasal cannula used?
Nasal cannulas are used to deliver oxygen when a low flow, low or medium concentration is required, and the patient is in a stable state.
