The main components of an Ambu bag (also known as a bag-valve-mask or BVM) include:
- Bag: The bag is the main component of the Ambu bag that the healthcare provider squeezes to deliver air to the patient. It is typically made of silicone or other durable materials and is designed to be reusable.
- Valve: The valve is the component that controls the flow of air into and out of the Ambu bag. It ensures that air flows in the right direction and prevents air from being forced into the patient’s stomach.
- Mask: The mask is the part of the Ambu bag that is placed over the patient’s face to deliver air. It is typically made of soft, pliable material and is designed to create a seal over the patient’s nose and mouth to prevent air leakage.
- Reservoir bag: The reservoir bag is a bag attached to the Ambu bag that helps increase the amount of oxygen available for the patient. It can store oxygen that is delivered to the patient during ventilation, and it can also collect exhaled carbon dioxide.
- Oxygen tubing: The oxygen tubing is a flexible tube that connects the oxygen source to the Ambu bag. It allows for the delivery of high concentrations of oxygen to the patient during ventilation.
- PEEP valve: PEEP stands for Positive End Expiratory Pressure. This valve is used to deliver a continuous positive pressure to the patient’s airway during exhalation. This helps keep the airway open and can improve oxygenation in certain patients.
- Pressure relief valve: The pressure relief valve is a safety feature that prevents excessive pressure from building up in the Ambu bag and the patient’s airway. It opens automatically when the pressure exceeds a certain level, allowing excess air to escape.
- Strap: The strap is used to secure the mask to the patient’s face during ventilation. It helps ensure a tight seal and prevents air leakage.
