Abstract:
The spectrum of disorders involving the tracheobronchial tree is diverse, with some of the conditions unique to the pediatric population. Despite the "airway first" maxim, many such disorders are missed initially. Tracheal bronchus is one such condition that comes to notice by persistent right upper lobe atelectasis, pneumothorax, recurrent pneumonia, chronic bronchitis, and prolonged ventilation. This anatomic variant in a patient with cyanotic congenital heart disease is reported. For this patient, timely identification of tracheal bronchus allowed appropriate changes in airway management and was life saving.

Acute Respiratory Failure-II
The underlying physiological abnormalities that contribute to hypoxemic respiratory failure include:
Alterations in Respiration II
In Biot's breathing, the respiratory rate and depth are irregular, alternating between periods of deep gasping and apnea. Common causes include...
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.
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,...
