In emergency medical situations, bag-valve-mask (BVM) resuscitation can be a lifesaving technique. However, misconceptions about its usage abound, leading to potential errors in practice. In this comprehensive guide, we’ll delve into the facts surrounding BVM resuscitation, debunking common myths along the way.

Understanding the Bag-Valve-Mask (BVM) Resuscitator

Before diving into the myths, it’s essential to understand what a BVM resuscitator is and how it functions. A BVM device consists of a self-inflating bag attached to a face mask and is utilized to provide positive pressure ventilation to patients who are not breathing adequately or at all. The bag is squeezed manually to deliver oxygen to the patient’s lungs.

Myth 1: BVM Resuscitation is Always Successful

Fact: While BVM resuscitation can be highly effective, it is not infallible. Success depends on various factors, including the skill level of the responder, the underlying cause of the respiratory distress, and the timeliness of intervention. Additionally, proper mask seal and adequate ventilation volumes are critical for success.

Myth 2: Anyone Can Perform BVM Resuscitation Effectively

Fact: While BVM resuscitation seems straightforward, it requires proper training and skill to perform effectively. Improper technique can result in inadequate ventilation, leading to poor outcomes for the patient. Healthcare providers should undergo regular training and practice to maintain proficiency in BVM ventilation.

Myth 3: BVM Resuscitation Always Requires High Flow Oxygen

Fact: While oxygen supplementation is typically provided during BVM resuscitation, high-flow oxygen may not always be necessary or appropriate. In certain cases, such as carbon monoxide poisoning, supplemental oxygen may exacerbate the condition. It’s essential to assess each patient individually and adjust oxygen delivery accordingly.

Myth 4: BVM Resuscitation Can Be Performed Indefinitely

Fact: While BVM resuscitation can sustain a patient temporarily, it is not a definitive treatment for respiratory failure. If the underlying cause of respiratory distress is not addressed promptly, the patient’s condition may deteriorate. BVM ventilation should be viewed as a bridge to more advanced airway management techniques or definitive care.

Myth 5: BVM Resuscitation Always Requires Two Rescuers

Fact: While having two rescuers can facilitate BVM ventilation, it is not always necessary. A single trained rescuer can effectively perform BVM ventilation in many situations. However, having a second rescuer available can provide assistance and support, especially during prolonged resuscitation efforts.

Myth 6: BVM Resuscitation Is Always Pain-Free for the Patient

Fact: While the primary goal of BVM resuscitation is to deliver oxygen to the patient’s lungs, the procedure can be uncomfortable, especially if the patient is conscious. The pressure from the mask and the force of ventilation may cause discomfort or pain, particularly if the patient has facial injuries or trauma.

Myth 7: BVM Resuscitation Is Always Successful in Pediatric Patients

Fact: While BVM resuscitation can be effective in pediatric patients, it poses unique challenges due to their smaller airway anatomy and higher respiratory rates. Proper sizing of the mask and adjustment of ventilation volumes are crucial in pediatric BVM resuscitation. Additionally, pediatric-specific BVM devices and techniques may be required for optimal outcomes.

Myth 8: BVM Resuscitation Is Only Effective in Hospital Settings

Fact: BVM resuscitation can be performed effectively in various settings, including pre-hospital environments, emergency departments, and intensive care units. Prompt initiation of BVM ventilation by trained personnel can significantly improve outcomes, regardless of the setting.


Bag-valve-mask (BVM) resuscitation is a vital intervention in the management of respiratory failure and cardiac arrest. By dispelling common myths surrounding BVM ventilation, healthcare providers can enhance their understanding and proficiency in this lifesaving technique. Proper training, skill maintenance, and adherence to evidence-based practices are essential for successful BVM resuscitation and improved patient outcomes.
