Abstract:
The case of a male, 61 years of age, presenting with occasional hemoptysis and shortness of breath (duration of 1 year) is reported. Congestive heart failure was presumed and supported by chest x-ray and echocardiography. The patient improved with diuretic and angiotensin converting enzyme (ACE) inhibitor therapy, but continued to experience cough and occasional hemoptysis. Bronchoscopy revealed numerous firm nodular projections within the trachea with distribution along the cartilaginous rings. Tracheopathia osteochondroplastica (TPO) was diagnosed. TPO is an uncommon, benign, but slowly progressive disease of unknown etiology. It is characterized by endoluminal projection of cartilaginous and bony nodules arising in the submucosa of the trachea. Involvement may extend to lobar or segmental bronchi. TPO should be considered in cases where cough, dyspnea, persistent pulmonary infection, hoarseness, or recurrent hemoptysis remain after appropriate treatment of other presumptive underlying causes.

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,...

Tracheostomy
A tracheostomy is a surgically created opening (stoma) in the anterior part of the trachea. It is used to establish a patient airway, bypass an upper airway obstruction, simplify the removal of secretions, permit long-term...
