Ventilation with a bag-valve-mask (BVM) is a crucial emergency skill. When endotracheal intubation or other definitive airway control is not possible, this fundamental airway management technique enables patients to be oxygenated and ventilated until a more permanent airway can be established. Basic BVM ventilation is frequently the only method of airway care available to the EMT. Using the bag valve mask ventilation in emergencies takes conscious practice. The patient's placement is the most critical aspect of this treatment. The tongue can occasionally fall towards the rear of the throat, occluding the airway. Using chin lift, head tilt procedures, or jaw thrust approach is the appropriate way to maintain the airway open. When necessary, the sniffing positions aid in opening the airway.

How to use the product?
A popular technique is to employ an oropharyngeal airway to move the tongue forward. When the patient is resting supine, this helps prevent occlusion. The patient's contraindication is the most specific for using a bag valve mask ventilation. The airway can be appropriately put beneath the tongue by either inserting it directly or rotating it 90 or 180 degrees. The rescuer ought to stand near the patient's head. Masks are worn with the pointed end above the nose and the curved end below the lower lip to create a robust facial seal.
Steps for success
- On the stretcher, the patient should be put on a flat platform. The medical professional raises the chin and tilts the head back. Head-tilting should be avoided in people who have spinal injuries.
- Two rescuers are often used to do BVM ventilation.
- Before fastening the bag, the first rescuer puts a mask on the patient's face and covers the mouth and nose with the mask.
- A second rescuer manually squeezes the bag to deliver oxygen to the patient via a mask or tube.
- A target rate of 10 ventilations per minute should be reached during ventilation.
Indications for use
- Pulmonary failure due to hypercapnia (A higher level of carbon dioxide and a lower level of oxygen in the blood)
- Abnormal mental condition with a failure to maintain an airway's protection
- Apnea (cessation of breathing)
- Respiratory failure due to hypoxia (less amount of oxygen and an almost average amount of carbon dioxide in the blood)
- Patients who have elective surgical procedures and are sedated
For successful ventilation when using this product, ensure the following;
- There is an open airway: The ventilation of the BVM might be impacted by any restriction or blockage in the airway.
- The mask should be well sealed to the face.
- Use the appropriate ventilation methods.
- For adequate oxygenation, ensure a valve is used
Aftercare for BVM ventilation
- Bag-valve-mask ventilation should continue until either a permanent artificial airway (such as an endotracheal tube) or sufficient spontaneous ventilation occurs (such as following naloxone administration for an opioid overdose).
- If endotracheal intubation is required, the patient should be pre-oxygenated by receiving 5 to 8 vital capacity breaths using a PEEP valve while being ventilated with maximum FiO2 through a non-rebreather mask 3 to 5 minutes, if possible.
- When doing BVM breathing on a patient while using an oropharyngeal airway, if the patient becomes more cognizant or if the gag reflex returns, remove the oropharyngeal airway and continue treatment as needed. Perhaps a nasopharyngeal airway would be more tolerable.
Complications related to using this product
- Hyperventilation or overventilation: Exhaling excessively quickly or in excess volume causes air to be forced into the stomach, causing gastric insufflation.
- Aspiration (entry of foreign items into the airway) (entry of foreign objects into the airway)
- Worsen the blockage in the airway
- Increase hypoxia (low oxygen level in the blood)
Factors to consider
- When possible, two-person bag-valve-mask (BVM) ventilation is used. One or two people can use a bag-valve-mask to ventilate, although two people are usually more efficient because a tight seal is necessary and requires two hands on the mask.
- A positive end-expiratory pressure (PEEP) valve may increase oxygenation during BVM. In cases where oxygenation is impaired even with 100% oxygen due to atelectasis, PEEP can promote alveolar recruitment and oxygenation.
PEEP has also been demonstrated to lessen lung damage. PEEP decreases venous return. Therefore it should be used with caution in patients who are hypotensive or pre-load dependent.
- When performing BVM ventilation, a pharyngeal airway adjunct is used unless it is contraindicated. If the patient's gag reflex is still functional, a nasopharyngeal airway (nasal trumpet) is utilized instead of an oropharyngeal airway. If ventilation is required, bilateral nasopharyngeal airways and an oropharyngeal airway are employed.
Bag valve mask ventilation turns out to be a beneficial strategy for dealing with people who are experiencing respiratory distress. To provide BVM ventilation, two methods are the one-person and two-person techniques. Two rescuers performing bag valve mask ventilation are more effective. Compared to intubation, this method is more straightforward and can save lives.
