Abstract:
Nasotracheal intubation is an essential component of anesthetic management for intraoral and mandibular surgeries. Direct nasotracheal intubation can occasionally be difficult and require an initial oral endotracheal tube (ETT) placement with subsequent conversion to a nasal ETT. Numerous techniques have been described. However, execution can be challenging and limited by available resources. This report re-examines conventional oral to nasal ETT conversion techniques and describes another innovative approach utilizing equipment more readily available in the operating room or as an option when difficulty is encountered with conventional conversion techniques.

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...

The ET tube comprises various components, including a standard adaptor to attach a bag-valve-mask (BVM) or ventilator, a cuff, a pilot balloon, and radiopaque markings along its length to measure the insertion distance. The tube sizes...
Endotracheal Tube Extubation
Procedure
Extubation removes the endotracheal tube (ETT) from the patient on mechanical ventilation. It requires a well-coordinated, multidisciplinary approach involving physicians, nurses, respiratory therapists, and other healthcare professionals.
