A must for NIOSH: certify fit performance of the half mask particulate respirator
1Division of Occupational Safety and Health, State of Washington, Tacoma, Washington 98402, USA. lofg235@lni.wa.gov
Abstract:
The National Institute for Occupational Safety and Health has proposed to amend the certification rules for half mask air-purifying particulate respirators. The amendment would require the certified respirator to fit a minimum percentage of the intended users. The fail/pass rate for a respirator fitting a worker population has not been part of the certification process for particulate respirators since 1995. The amendment would also add a new requirement for the manufacturer to inform whom the respirator is intended to fit.

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:
PPE Use in Healthcare Settings I: Donning
Tracheostomy Care II: Procedure
Step 1: Perform hand hygiene, and put on personal protective equipment: gown, gloves, mask and...
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 percentage setting:...
