Must-Know Methods of Artificial Ventilation

When natural breathing isn't enough, artificial ventilation becomes a lifesaver. For patients who can't breathe on their own, the right ventilation techniques can drastically improve survival rates and recovery outcomes. Let's dive into some essential artificial ventilation methods with Bever Medical.    
 

Natural vs. Artificial Ventilation  

Natural Ventilation

This relies on the patient's own breathing, driven by the diaphragm and intercostal muscles to exchange gases. It's how the body is designed to function.  

Artificial Ventilation

Here, external forces assist or fully take over breathing. Methods include positive pressure ventilation (e.g., bag-valve mask) or negative pressure ventilation (like the historic iron lung).  

Artificial ventilation quickly restores oxygen exchange when natural breathing is impaired or stops. It requires skilled operators, as improper use can lead to airway damage or over-ventilation.

Managing Airway Obstructions  

Airway obstruction, especially common in children and older adults, can block airflow. Recognizing and clearing these blockages is critical in emergencies.  

Common Signs

Inability to speak or severe coughing.  

Cyanosis (blue lips or skin) or sudden loss of consciousness.  

Solutions

Back Blows and Abdominal Thrusts (Heimlich Maneuver): Quickly dislodge objects for conscious patients.  

Tools to the Rescue: Suction devices or laryngoscopes can remove stubborn obstructions.  

Nasal Pharyngeal Airway (NPA): Particularly useful for partial blockages or soft tissue collapse caused by the obstruction.   

Airway Management Techniques  

Artificial ventilation starts with effective airway management. Here are some proven techniques

Head Positioning

Head Tilt-Chin Lift: A go-to for most cases to open the airway.  

Jaw Thrust: Ideal for patients with potential neck injuries—it avoids moving the cervical spine.  

Equipment Help

Nasal Pharyngeal Airway (NPA): Easy to insert and great for patients with clenched teeth.  

Oral Pharyngeal Airway (OPA): Perfect for unconscious patients, keeping the tongue from blocking the airway.   
 

Airway Devices  

The Nasopharyngeal Airway (NPA) is a simple device, Bever Medical uses premium PVC or silicone that's soft and durable.   

When to Use

• Ideal for patients with clenched jaws but with some natural breathing.  

• Works well with suction devices to clear airway secretions.  

Pro Tip: Always apply lubricant before insertion to minimize discomfort or injury.   

Oral Pharyngeal Airway (OPA)

Best For: Unconscious patients to prevent the tongue from obstructing the airway.  

How To Use: Choose the right size and insert following its curve to avoid injuring the mouth.   

Laryngeal Mask Airway (LMA)

Great For: Short procedures under anesthesia or challenging airways.  

Advantages: Easy to insert and avoids complications tied to intubation. 

Bag-Valve Mask Ventilation (BMV)  

BMV is one of the most common artificial ventilation techniques, widely used in emergencies and surgeries.   

Steps to Perform:

1. Select a mask that fits snugly on the patient's face.  

2. Connect the bag and manually compress to deliver positive pressure ventilation.  

3. Pair it with an NPA or OPA for a clear airway.   

Key Tips

• Avoid over-ventilation to prevent stomach inflation or lung damage.  

• Watch the chest rise to ensure proper ventilation.
