Bag-mask ventilation is arguably the most important aspect of effective oxygenation and ventilation, and can be life-saving in emergency situations in which patients are not able to breathe adequately. Bag-mask ventilation is indicated for patients who are unable to breath on their own. This can be following the administration of drugs, due to underlying respiratory failure, or following failed airway management.
A bag-mask ventilation system requires the following an appropriate-sized face mask; a self-inflating bag to deliver an appropriate tidal volume; a non-rebreathing valve; an oropharyngeal or nasopharyngeal airway; and an oxygen source. There are three important components for a proper bag-mask ventilation technique-- mask seal, airway opening, and ventilation.
First, a tight seal with an appropriately sized face mask around the oral and nasal cavities is essential so that the bottom margin of the mask is placed in the groove between the patient's lower lip and chin, and the upper margin of the mask sits in the bridge of the nose. The mask is secured in place with the thumb and index finger of the non-dominant hand. Excessive downward pressure on the patient's mandible should be avoided, and to avoid obstruction of the airway, the mandible should be lifted to meet the mask.
Secondly, patency of the airway is required in order to ensure passage of gases. Open the airway by performing a jaw thrust using the third, fourth, and fifth digits of the non-dominant hand. The third and fourth digits are hooked under the body of the patient's mandible, and the fifth digit is placed under the mandibular angle. This positioning is used to lift upward and elevate the patient's mandible to create an open airway.
For the last step in ventilation, the dominant hand is used to manually compress the bag to deliver oxygenated gas to the patient. A visible chest rise is indicative of successful airflow. When difficult airway patency is encountered, an exaggerated jaw thrust may be beneficial. In some situations a two person technique could be employed to create a better mask seal. This involves using a two-handed jaw thrust while the second person manually compresses the bag.
Application of an appropriately sized oropharyngeal, or nasopharyngeal airway can assist with clearing a potential obstruction of the airway, particularly by preventing the tongue from obstructing the oropharynx. Other troubleshooting techniques include moving the mask from side to side to help create a better seal, or choosing a different size or type of mask to create a better seal, particularly in patients with facial hair.
Bag-mask ventilation is often considered the initial airway management technique in emergency situations and resuscitation. Proper technique is important for effective gas exchange. Anticipation of possible difficulties in executing bag-mask ventilation and effective troubleshooting methods are critical to successful oxygenation using this technique.
