APPLICATION OF APNEIC OXYGENATION IN TRACHEAL SURGERY
Background:
The tracheal surgery is associated with opening of airways and historically used different methods of maintaining gas exchange: System "shunt-breathing", the injection ventilation, high frequency jet ventilation and even artificial circulation. In recent years increased the interest of use of apneic oxygenation (A 0).
The Aim:
to study the impact ofthe application ofA o on the gas exchange, acid-base balance of arterial blood, in patients undergoing reconstructive surgery on the trachea and bronchi with AO.
Materials And Methods:
The study included 130 patients with stenotic disease of the trachea, operated in the period from 2011 to 2014 usingAO.
Results:
Application ofAO provides a high level of oxygenation and is accompanied by a moderate increase in pCO2 level and the development of acidosis. Hypercarbia and acidosis were not accompanied with hemodynamic disturbances on ECG, heart rate and invasive measurement of blood pressure at high values of Pa O₂.

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.
Equipment
The equipment necessary for this procedure includes:
Special considerations while measuring oxygen saturation
Ensuring accuracy in vital sign recordings while prioritizing patient comfort and minimizing anxiety is...
