Infant Airway Obstruction Model – A Step-by-Step Guide to Mastering the Heimlich Maneuver

Infant Airway Obstruction Model ——A Step-by-Step Guide to Mastering the Heimlich Maneuver

As a cornerstone component of Cardiopulmonary Resuscitation (CPR), the Heimlich Maneuver stands as a critical first-aid intervention for resolving airway obstruction and preserving upper airway patency. It plays an irreplaceable role in rescuing infants experiencing foreign body-induced airway blockages. Engineered with high-fidelity simulation, the advanced infant airway obstruction model replicates real-world emergency scenarios, enabling learners to master the full workflow of "foreign body identification standardized rescue" with precision. Below is a detailed breakdown of its usage:

Step 1: Simulate the Obstruction Scenario

Gently insert the dedicated simulated foreign body (a black sponge block) into the throat region of the simulated infant’s mouth. This setup accurately mimics the urgent scenario of an infant’s airway blocked by a foreign object, providing a realistic foundation for rescue practice.

Step 2: Secure Positioning and Airway Preparation

Straddle the simulated infant across one of your forearms. Use the palm of this arm to stabilize the infant’s head and neck: rest the base of your palm against the back of the head, and use your fingers to lightly support the jaw (avoid applying pressure to the soft tissues under the chin).

With your other hand, stabilize the infant’s mandibular angle. Maintain a mild head tilt to keep the airway in a semi-open state—this readies the airway for subsequent foreign body removal attempts.

Step 3: Back Blows for Foreign Body Expulsion

Use your supporting forearm to gently roll the simulated infant into a prone position (chest-down, back-up). Key Posture Tip: Keep the infant’s head lower than their torso (head-low, feet-high) to leverage gravity for easier foreign body expulsion.

Using the heel of your free hand, deliver 4 quick, firm blows to the midpoint of the line connecting the infant’s two shoulder blades. Blows should be forceful enough to dislodge the foreign body but controlled to avoid injury.

Immediately inspect the mouth after the 4th blow. If the black sponge block (simulated foreign body) is visible, use your fingers (or sterile tweezers, if available) to gently extract it—take care not to push the foreign body deeper into the airway.

Step 4: Chest Thrusts for Persistent Obstruction

If back blows fail to expel the foreign body:

Swiftly reposition the simulated infant: use both forearms to stabilize their body, then roll them into a supine position (back-down, chestup). Safety Note: Keep the infant’s head turned to one side to prevent the foreign body from shifting into the opposite airway.Locate the compression point: 1 finger’s width below the midpoint of the line connecting the infant’s two nipples.

Apply 4 rapid, impulsive downward thrusts with your thumb. Adjust pressure to be firm (sufficient to generate upward force on the diaphragm) but gentle enough to avoid damaging thoracic organs (e.g., lungs, heart).

Recheck the mouth immediately after the 4th thrust. If the foreign body is expelled, remove it promptly with your fingers.

Step 5: Repeat Sequence for Unresolved Obstruction

If the foreign body remains lodged after one cycle of "4 back blows + 4 chest thrusts," repeat the entire sequence cyclically. Continuously monitor the simulated infant’s state throughout—adjust your technique (e.g., pressure, angle) if needed to avoid secondary injuries from improper handling.

By practicing repeatedly with this model, learners will develop proficiency in both identifying infant airway obstruction and executing the Heimlich Maneuver to standard. SCMEHE provides the most suitable simulation models for such Heimlich Maneuver training. This training equips individuals to respond swiftly and scientifically in real life emergencies, ultimately safeguarding the lives of infants at risk of airway obstruction.
