Background:
Respirators have received much attention since the outbreak of the COVID-19 pandemic. Due to a substantial shortage of the most commonly used respirator, the N95 Filtering Facepiece Respirator (N95), as well as the desire to have added protection while performing aerosol generating procedures (AGPs), dental healthcare personnel (DHCP) have considered alternative respirator options. It is well documented in the medical literature that the Powered Air-Purifying Respirator (PAPR) provides better protection against respiratory pathogens; however, there are no reported cases that describe the use of PAPRs in the dental setting. This survey report evaluates the use of a loose-fitting full facepiece PAPR by different dental providers.
Objective:
To determine if a PAPR can be used in the dental setting and identify any potential barriers to use.
Methods:
Eleven DHCP representing general dentistry, dental hygiene, pediatric dentistry, endodontics, orthodontics, oral and maxillofacial surgery and maxillofacial prosthodontics at Walter Reed National Military Medical Center (WRNMMC) and Naval Postgraduate Dental School (NPDS) were asked to wear the MAXAIR PAPR while performing an AGP. They then completed a 14-question survey.
Results:
There was a 100% response rate. All DHCP with the exception of the endodontist were able to successfully wear the MAXAIR PAPR for the duration of their procedure. All DHCP reported that the PAPR was more comfortable than expected. There were no reports of fogging or hindrance to visibility, breathing was unaffected or enhanced, and the noise level was tolerable. Average time to don and doff the PAPR was 5 minutes. All DHCP were able to wear loupes; some were not able to wear a headlight. Two DHCP reported a history of mild claustrophobia, and both were able to tolerate the PAPR without any issue. 44% preferred the PAPR over the N95.
Conclusion:
This preliminary survey of a loose-fitting PAPR in the dental setting suggests there is a place for PAPRs in the dental community.

01:30Administering 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:

Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...

01:16Oxygen 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,...
01:26Oxygen 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.
