RFQ Details

Nasal Cannula Tube Adult and Pead's. The nasal cannula is a device used to deliver supplemental oxygen or increased airflow to a patient or person in need of respiratory help. This device consists of a lightweight tube that on one end splits into two prongs which are placed in the nostrils and from which a mixture of air and oxygen flows. A nasal cannula is generally used wherever small amounts of supplemental oxygen are required, without rigid control of respiration, such as in oxygen therapy. Most cannulae can only provide oxygen at low flow rates�"up to 5 liters per minute (L/min)�"delivering an oxygen concentration of 28�"44%. Rates above 5 L/min can result in discomfort to the patient, drying of the nasal passages, and possibly nose bleeds (epistaxis). Also with flow rates above 6 L/min, the laminar flow becomes turbulent and the oxygen therapy being delivered is only as effective as delivering 5�"6 L/min.

The nasal cannula is often used in elderly patients or patients who can benefit from oxygen therapy but do not require it to self respirate. These patients do not need oxygen to the degree of wearing a non-rebreather mask. It is especially useful in those patients where vasoconstriction could negatively impact their condition, such as those suffering from strokes.

A nasal cannula may also be used by pilots and passengers in small, unpressurized aircraft that do not exceed certain altitudes. The cannula provides extra oxygen to compensate for the lower oxygen content available for breathing at the low ambient air pressures of high altitude, preventing hypoxia. Special aviation cannula systems are manufactured for this purpose.

Since the early 2000s, with the introduction of the nasal cannula which uses heated humidification for respiratory gas humidification, flows above 6 LPM have become possible without the associated discomfort and with the added benefit of improving mucociliary clearance. Kindly contact
