Using an Ambu bag (Bag Valve Mask or BVM) on pediatric and neonatal patients requires extreme precision because their lungs are fragile and their anatomy is small.
Below is a structured description of the procedure and key safety measures.
1. Preparation & Equipment Selection
Choosing the correct size is the most critical first step to avoid lung injury (barotrauma) or ineffective ventilation.
Neonatal/Infant (Preterm to 1 year): Use a 240–300 mL bag.
Pediatric (1 year to puberty): Use a 450–500 mL bag.
Mask Fit: The mask must cover the bridge of the nose, the mouth, and the cleft of the chin without pressing on the eyes (which can cause a slow heart rate).
2. Positioning the Airway
Children have a relatively large back-of-the-head (occiput) and a floppy airway.
Neutral/Sniffing Position: Place the child on a flat surface. For infants, place a small rolled towel under the shoulders to keep the neck in a "neutral" position.
Avoid Over-extension: Do not tilt a baby’s head back as far as an adult’s; this can actually collapse their soft airway.
3. The "E-C" Grip Technique
To ensure an airtight seal:
The "C": Use your thumb and index finger to form a "C" over the mask, pressing it firmly down onto the face.
The "E": Use your remaining three fingers to form an "E" under the jawbone (mandible). Lift the jaw up into the mask rather than pushing the mask down onto the face.
Caution: Avoid pressing on the soft tissue under the chin, as this can block the airway.
4. Ventilation Technique (Squeeze & Rate)
Volume: Squeeze only until you see a visible, gentle chest rise. Do not "empty" the bag; for se
neonates, you may only need two fingers to squeeze.
Rate:
Neonates: 40–60 breaths per minute (Rhythm: "Squeeze-two-three-Squeeze").
Pediatric: 20–30 breaths per minute (1 breath every 2–3 seconds).
Pressure Release: Ensure the Pop-off Valve (usually set to 35–45 is active to prevent excessive pressure from popping the lungs.
5. Monitoring Effectiveness
You know the Ambu bag is working if:
The chest rises and falls with every squeeze.
The heart rate begins to increase (the best sign of success in newborns).
The skin color improves (from blue/grey to pink).
