For human use, tubes range in size from 2 to 10.5 mm in internal diameter (ID). The size is chosen based on the patient's body size, with the smaller sizes being used for pediatric and neonatal patients. Tubes larger than 6 mm ID usually have an inflatable cuff. Originally made from red rubber, most modern tubes are made from polyvinyl chloride ...
Tubes constructed of silicone rubber, wire-reinforced silicone rubber or stainless steel are also available for special applications. For human use, tubes range in size from 2 to 10.5 mm (0.1 to 0.4 in) in internal diameter.

Chest tube have an end hole (proximal, toward the patient) and a series of side holes. The number of side holes is generally 6 on most chest tubes. The length of tube that has side holes is the effective drainage length (EDL). In chest tubes designed for pediatric heart surgery, the EDL is shorter, generally by only having 4 side holes. [17]
Cuffed tracheostomy tubes have inflatable balloons at the end of the tube to secure them in place. A tracheostomy tube may be fenestrated with one or several holes to let air through the larynx, allowing speech. [7] Special tracheostomy tube valves (such as the Passy-Muir valve [8]) have been created to assist people in their speech. The ...
There are six sizes of the laryngeal tube, ranging from newborn (size 0) to large adult (size 5). The connector of the tube is color-coded for each size. The different sizes are calibrated according to weight or height. [2] The laryngeal tube was licensed for use during cardiopulmonary resuscitation in Japan in 2002, [2] and approved for use in ...
