Abstract:
We have tested the influence of face-mask style and volume on rhinomanometric measurements. Using an artificial head-and-piston pump to standardize the test conditions, four types of face masks (volumes varying from 120 to 200 ml) have been tested in a series of 20 measurements per mask. No statistical difference could be found between the series using a Chi-square test. We conclude that there is no influence of form and volume of the face mask on the accuracy of the rhinomanometric measurement.

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.

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.
