Abstract:
The production of gaseous oxygen when hydrogen peroxide interacts with tissue is a well-known phenomenon that has been reported as a rare cause of gas embolism. We present the case of an 11-month-old infant who sustained an immediate cardiorespiratory arrest following the use of this agent during a minor surgical procedure. Clinical features, radiological findings and the rapid response to resuscitation were strongly suggestive of major gas embolism. Adverse effects of inappropriate use of hydrogen peroxide, and the diagnosis and management of these problems are discussed.

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,...

Administering Oxygen by Mask
Administering oxygen by mask is a common nursing intervention that provides supplemental oxygen to patients with respiratory distress or chronic lung conditions. This procedure involves delivering oxygen at a specified rate through a face mask connected to an oxygen source.
