Ambu Man – Chest Spring Thin Set + Thorax Spring – Original Compression System for Realistic Resistance

Equip your CPR dummy with accurate and adjustable chest resistance.

The Ambu Man thin chest spring set + thorax spring is an original replacement set used to restore or adjust the internal compression mechanism of the Ambu Man resuscitation dummy. This set provides natural, lightweight chest resistance , ideal for training sessions where realistic but not maximum force is required – for example, with less powerful trainees, beginners, or during prolonged practice sessions.

The springs are designed to allow the chest to spring back in a controlled manner after each compression, in accordance with the resuscitation guidelines of the European Resuscitation Council (ERC) and the American Heart Association (AHA).

Application

This set is used for:

• Replacement of worn or broken breast springs
• Adjustment of compression resistance (lighter spring than standard)
• Maintenance of the thoracic mechanism in the Ambu Man
• BLS, BHV, and First Aid training where correct compression depth and rebound are essential

The included thoracic spring supports the structure of the rib cage and works together with the chest spring for consistent feedback during the exercise.

Package contents

• 1x Thin breast spring (compression spring)
• 1x Thorax spring (support spring)
• Packaged as a set, ready for direct assembly in the doll.

Technical specifications

• Product name: Ambu Man – Chest spring thin set + thoracic spring
• Material: Reinforced steel / spring steel
• Color: Metallic (may vary by batch)
• Spring pressure: Reduced compared to standard spring
• Mounting position: Internal chest structure (centrally below compression zone)
• Use: For training purposes only
• Lifespan: Multiple training cycles with correct use and maintenance

Installation and use

1. Open the chest of the Ambu Man resuscitation dummy
2. Carefully remove the old breast feather and thoracic feather.
3. Mount the new springs in the designated positions.
4. Check if the chest moves freely and springs back correctly after compression.
5. Close the torso and test the functionality before training use.

Installation is simple and requires only basic tools such as a screwdriver or Allen key (depending on the doll's model year).

Maintenance and replacement

• Inspect the springs regularly for deformation, cracks, or loss of tension.
• Clean only with a dry cloth; do not grease or treat with lubricant
• Replace immediately in case of mechanical failure, cracking noises, or abnormal rebound.
• Store spare springs in a dry environment to prevent corrosion.

Points of attention

• This set is intended for lighter resistance than standard – not suitable as a substitute for heavy compression training.
• Only use within the original mechanism of the Ambu Man
• Not suitable for medical use or live patient simulation
• Replacing springs extends the lifespan and accuracy of the resuscitation dummy.
