A polyvinylchloride (PVC) tube is used to make (ETTs), which are used to intubate patients. These tubes allow for the direct administration of oxygen (O2) and the removal of carbon dioxide (CO2) from the lungs. They help to keep the lungs' airways open and enable mechanical breathing. Additionally, they are used for intermittent positive pressure ventilation (IPPV), resuscitation, diphtheria, epiglottis, and direct suctioning of the trachea during meconium aspiration to protect the lungs from contamination by gastric contents and nasopharyngeal debris. They make it possible for medical experts to execute the surgery and sedate the patient. ETTs are therefore frequently utilised in surgical facilities, trauma centres, and intensive care units (ICUs).
