AMBU Full Form: Introduction, Components, Mechanism, Benefits

An artificial manual breathing unit (AMBU bag), also known as a self-inflating bag or manual resuscitator, is a device used to provide positive pressure ventilation to a patient who is not breathing or is breathing inadequately. It is a hand-held device that consists of a flexible bag, a reservoir mask, and a one-way valve. The bag is compressed by the rescuer, which forces oxygen into the patient’s lungs.



An artificial manual breathing unit (AMBU bag), also known as a bag valve mask (BVM) or manual resuscitator, is a hand-held device used to provide positive pressure ventilation to a patient who is not breathing or is breathing inadequately. It consists of a flexible bag, a reservoir mask, and a one-way valve.

The rescuer compresses the bag, which forces oxygen into the patient’s lungs. AMBU bags are used in a variety of settings, including ambulances, hospitals, and emergency situations. They are also used in some surgical procedures and during resuscitation.

Here is an introduction to the different components of an AMBU bag:

  • Bag: The bag is the main part of the AMBU bag. It is made of a flexible material, such as silicone or rubber. The bag is compressed by the rescuer to force oxygen into the patient’s lungs.
  • Reservoir mask: The reservoir mask is a clear plastic mask that fits over the patient’s mouth and nose. It has a one-way valve that allows oxygen to flow into the patient’s lungs, but prevents air from flowing back out of the lungs.
  • One-way valve: The one-way valve prevents air from flowing back out of the patient’s lungs during exhalation.

Components and Mechanism of AMBU

Component Description
Control Interface Allows manual adjustment of breathing parameters such as breath rate, tidal volume, and ratios.
Sensor System Measures oxygen levels, carbon dioxide levels, and respiratory rate for monitoring and adjustment.
Pressure Regulator Maintains and adjusts the pressure and airflow to simulate the natural breathing process.
Breathing Circuit Tubing and connectors that deliver air/oxygen and expel exhaled air.
Reservoir Bag Stores excess oxygen/air to ensure a consistent supply during the breathing cycle.
Valves One-way valves to direct airflow and prevent rebreathing of exhaled air.
Filters Removes impurities or particulates from the air being inhaled.

Mechanism of Operation:

  1. Breathing Regulation: Users manually adjust breathing parameters (breath rate, tidal volume) through the control interface.
  2. Air/Oxygen Delivery: A controlled flow of air or oxygen is delivered to the user based on the manual settings.
  3. Pressure Regulation: The pressure regulator maintains a consistent pressure to simulate natural breathing.
  4. Monitoring and Feedback: Sensors monitor oxygen, carbon dioxide levels, and respiratory rate, providing feedback to users for adjustment.

Benefits and Applications of AMBU

Potential Benefits:

  1. Emergency Situations: In critical situations where a person is unable to breathe on their own or needs assistance, an artificial manual breathing mechanism can provide crucial support until more advanced medical intervention is available.
  2. Respiratory Training: Such a system could be used in medical training and simulations to teach healthcare professionals how to manually regulate and control a patient’s breathing in various scenarios.
  3. Assisted Breathing: For individuals with compromised respiratory functions, an artificial manual breathing unit could assist in maintaining proper breathing patterns, improving oxygenation, and providing relief.

Potential Applications:

  1. Medical Training Simulations: Simulation of breathing scenarios for medical students and healthcare professionals to practice manual breathing techniques and emergency response.
  2. Respiratory Therapy: Temporary assistance for individuals with respiratory conditions, helping them maintain adequate breathing until their condition stabilizes or more advanced support is available.
  3. First Aid and Emergency Response: In emergencies such as cardiac arrest or near-drowning incidents, a manual breathing unit could assist in providing essential oxygen and aiding resuscitation efforts.
  4. Research and Development: Researchers might utilize such a system to study breathing patterns, test new medical devices, or develop improved strategies for managing respiratory distress.

Operating and Administering

1. Training and FamiliarizationEnsure operators are adequately trained on the device’s functionalities, safety procedures, and emergency protocols.
2. Patient AssessmentConduct a thorough assessment of the patient’s respiratory status, medical history, and specific requirements. Ensure the patient is a suitable candidate for assistance from the artificial manual breathing unit.
3. Positioning and ComfortPosition the patient comfortably, ensuring proper head positioning and clear airways for effective breathing.
4. Setting ParametersSet appropriate parameters (e.g., breath rate, tidal volume) based on the patient’s needs and under guidance from healthcare professionals. Adjust settings as required during the operation.
5. MonitoringContinuously monitor the patient’s vital signs, including heart rate, blood pressure, oxygen saturation, and respiratory rate throughout the operation. Respond promptly to any changes in the patient’s condition.
6. CommunicationMaintain clear and reassuring communication with the patient throughout the procedure to alleviate anxiety and discomfort, explaining the process and providing support.

Training and Certification


  1. Formal Education and Degrees: Professionals typically start by pursuing relevant degrees such as Bachelor of Science in Nursing, Bachelor of Medicine, Bachelor of Surgery, etc., based on their area of specialization.
  2. Specialized Training Programs: Professionals undergo specialized training programs specific to the medical equipment or procedure they will be involved with. For operating and administering an artificial manual breathing unit, they would undertake training related to respiratory therapy or emergency medical procedures.
  3. On-the-Job Training: Professionals receive hands-on training during their clinical rotations, internships, or residencies. This training is crucial for familiarizing them with real-world scenarios and equipment usage.


  1. Board Certifications: After completing formal education and relevant training, healthcare professionals may pursue certifications from recognized boards or organizations related to their field of practice.
  2. Specialized Certifications: Professionals can obtain specialized certifications related to the operation and administration of specific medical equipment or procedures. In the case of respiratory therapy or artificial manual breathing units, they might pursue certifications specific to respiratory care.

Artificial Manual Breathing Technology” is an imagined concept that envisions the integration of innovative technologies to assist and optimize manual breathing processes. While not a current recognized term in medical practice, the theoretical concept suggests the incorporation of cutting-edge advancements such as artificial intelligence (AI), advanced sensors, miniaturization, portability, wireless connectivity, and customizable breathing patterns.


An Artificial Manual Breathing Unit is a hypothetical term describing a device or system that assists in or replicates the manual control and regulation of a person’s breathing, typically through technological or mechanical means.

The working of an Artificial Manual Breathing Unit would involve mechanisms and technologies to regulate airflow, adjust breathing parameters, and simulate natural breathing processes. The specifics would depend on the design and purpose of the unit, which is hypothetical at this point.

“Artificial Manual Breathing Unit” is not a recognized or standardized medical term or device. It is a conceptual phrase implying a device that assists or replicates manual breathing, but its practical existence or standardization in the medical field is not confirmed.
