“…A nasal mask or a toddler-sized mask with the lower border resting above the patient's upper lip can provide adequate seal if the patient's mouth is occluded with a hand or dressing. 21 The nasal mask may also relieve airway obstruction as described in the next section. The double nasopharyngeal tube, which delivers positive pressure directly to the pharyngeal cavity, 22 is no longer commercially available, but successful utilization of an ordinary nasopharyngeal airway connected to an endotracheal tube adapter while compressing the contralateral nostril has been described.…”

Mask ventilation is lifesaving, especially in cases of difficult intubation. Many publications have offered distinct techniques for optimizing mask ventilation. This article reviews currently available difficult mask ventilation literature and theory. We divide difficult mask ventilation into 3 broad categories based on etiology: inadequate mask seal, increased airway resistance, and decreased respiratory compliance. Published strategies for overcoming difficulty are presented and organized by etiology.

“…Another method suggested is to use a large-size transparent Tegaderm dressing to be applied over the face, with the outer edges extending over the beard to the neck, and then creating an opening through the mouth for ventilation [12]. An additional method has been described by Rao et al [13], suggesting assessing the patency of the nostrils, inserting a lubricated nasal airway through the most patent nostril, using a suitable-sized toddler mask and ventilating through the nose. However, none of the previously suggested methods assessed the effectiveness in improving the ventilation.…”

Using gel for difficult mask ventilation on the bearded patients: a simulation-based study

The beard is a well-known cause of difficult mask ventilation due to excessive air leaks. Various techniques have been proposed to overcome this difficulty, such as applying a gel on the mask edge. Our objective was to determine whether the gel technique will improve ventilation and to assess the comfort of the provider. A randomized crossover design was conducted to assess the efficacy of gel in a bearded simulation model. Respiratory therapists (RT) were recruited by convenience sampling to hold the mask using a two-handed technique for a two-minute ventilation session. During the session, the ventilator provided a fixed Tidal Volume (TV) of 550 mL and a respiratory rate of 12 per minute, and the simulated model measured the received volumes. We compared the median TV and number of failed ventilation attempts with or without the gel. The comfort level while using the gel was assessed with constructed questions. We recruited 74 respiratory therapists working in Riyadh city. More than half of the participants had more than 5 years experience. The median tidal volume for standard mask ventilation without the gel was 283 mL [interquartile range (IQR) 224, 327], whereas that with the gel was 467 mL [451, 478], respectively (p < 0.01). The number of successful ventilations was recorded out of 24 breaths during the 2-min ventilation period for each technique; the proportion of successful ventilations increased significantly by 65% (95% CI 51-75%, p < 0.01) with the gel. In addition, only nine participants believed the technique was not comfortable, while the remaining individuals found it comfortable or natural. In our bearded simulation model, applying the gel significantly improved ventilation without negatively affecting comfort. Further studies and education are encouraged in the field of basic airway management.
