Bag-Valve-Mask Ventilation

Bag Valve Mask (BVM) Ventilation is an emergency procedure. This technique ensures supply of oxygen and ventilation until a definitive airway is established.

In hospitals, emergency medical technicians use basic BVM ventilation for airway management.

It is indicated as prehospital airway support in children. Bag is collapsible, self-expanding and made of silicone.

BVM valve system enables one-way airflow. Mask is placed over nose and mouth which forms an airtight seal.

This ventilation technique is used for patients with respiratory failure, failure of ventilation or both.

BVM ventilation is used in patients who are not able to breathe spontaneously.

BVM ventilation is indicated for various medical emergencies situations. e.g. cardiac arrest, respiratory failure

If mask is not placed fit on the patient’s face, then this technique may not deliver enough oxygen supply.

Manage airway very carefully in patients with unstable cervical spine injuries to avoid movement.

If this ventilation procedure fails due to any reason, then surgeons should consider alternative airway management methods for good results.

This procedure stabilize normal CO2 levels, hence prevents respiratory acidosis.

BVM ventilation stabilizes respiratory status in distressed patients which prevents deterioration.

CPR with oxygenation and ventilation increases successful resuscitation and improves outcomes.

Adequate BVM ventilation lowers hypoxia risk and organ dysfunction complications.
