Abstract:
This is the second of a two-part unit on the use of emergency oxygen in adults. Part 1 outlined the main recommendations of the recently published British Thoracic Society guidance. It also examined managing breathlessness in non-hypoxaemic patients. This part discusses some potential changes to clinical practice and provides practical examples on administering oxygen to patients with acute asthma and COPD. It also outlines issues around administering oxygen that lack evidence and need good-quality studies.

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:
Inhaled Medications
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.
