Recognition and management of cardiopulmonary arrest
Published in Peate Ian, Dutton Helen, Acute Nursing Care, 2020
A pocket mask (Figure 7.13) is used to safely deliver rescue breaths during a cardiac arrest. It can easily be used by one person as both hands are free to hold the mask firmly to the face, maintaining an airtight seal. It should be used in conjunction with an appropriately sized Guedel airway. Pocket masks are often situated in key areas and, as such, are often available before the crash trolley arrives. They have the benefit of ease-of-use.

Cardiopulmonary resuscitation quality during CPR practice versus during a simulated life-saving event
Published in International Journal of Occupational Safety and Ergonomics, 2018
Firefighters perform CPR wearing personal protective clothing and self-contained breathing apparatus. Studies show that there is a risk that patient ventilation will be hampered when wearing personal protective clothes [10]. This does not correlate with our study, where patient ventilation had a mean of 78% in the group wearing protective clothing and self-contained breathing apparatuses. This result is probably due to the participants taking off the face mask of their breathing apparatus to ventilate the patient with a pocket mask. The fire brigade in Sweden always ventilates the patient using a pocket mask with additional oxygen flow. In the military context, pocket masks have proved to require repeated training to master, but with training resulted in a ventilation of 97% [20]. Jeong et al. [26] argue that basic airway management, such as pocket masks, leads to lower survival chances for patients, as compared to advanced airway management. On the other hand, Ohashi-Fukuda et al. [27] show that there is no difference in neurologically favorable survival between advanced airway management and basic airway management.
Prehospital Manual Ventilation: An NAEMSP Position Statement and Resource Document

Whenever possible, EMS clinicians should perform BVM ventilation using a two-person technique, with one rescuer maintaining a two-handed mask seal and the other managing bag insufflation. Maintaining an adequate seal while opening the airway is one of the most difficult aspects of BVM ventilation. The chaotic and uncontrolled environment of field resuscitations is likely to make one-person BVM ventilation even more difficult and increase the need for modifications that improve success. Two-person BVM technique ensures that one operator can maintain a two-hand mask hold, which increases the mean tidal volume delivered for both adult and pediatric patients (24–30). Further evidence of the importance of a two-handed mask grip is provided by Elling and Politis who demonstrated that more than half of EMS clinicians were not able to provide effective ventilations when operating the BVM alone and that a two-hand grip with a pocket mask outperformed use of a BVM with a one-handed mask seal (31). Multiple studies in the operating room and simulation settings illustrate the difficulty of BVM ventilation performed by a single clinician, as well as the superiority of the two-person technique in delivering consistent tidal volumes (24–29). Hess and Baran found tidal volumes delivered by one person to be less than half that delivered with a two-person BVM, mouth-to-mouth, or mouth-to-mask ventilation technique (24). In a simulated cardiac arrest resuscitation with two EMS clinicians, Gerber et al. found improved CPR quality and higher tidal volumes that were closer to the target range using two-person manual ventilation where one rescuer maintained a two-handed mask seal and the other rescuer performing chest compressions squeezed the resuscitator bag during the pause for ventilations (27).
