Emergency oxygen for respiratory patients
1Edge Hill University/Respiratory Education UK.
Abstract:
Oxygen is prescribed for hypoxaemic patients to increase alveolar oxygen tension and decrease the effort of breathing. Although principally life saving, in certain circumstances it can be lethal if prescribed and/or administered incorrectly. To ensure safe, effective delivery of oxygen, health professionals dealing with the administration, titration and monitoring of oxygen therapy should understand the principles that underpin its use. Carol Kelly and Anne Riches discuss administering oxygen therapy in the acute situation.

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:
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,...

Oxygen Delivering System I: Nasal Cannula and Face Mask
Nasal Cannula
A nasal cannula is a lightweight tube split at one end into two prongs and placed in the nostrils. It is typically used to deliver low to medium levels of oxygen.
Suggested flow rate: The suggested flow rate for a nasal cannula typically ranges between 1 and 6 L/min.

Respiratory Assessment: Purpose and Indications
Objectives and Importance:
The primary goal of respiratory assessment is to evaluate patients at early risk of clinical deterioration. Since respiratory distress often precedes other signs of declining health, breathing patterns and sounds become a...
