1. **Positional fixation:** To ensure that the gastric tube is positioned correctly and to prevent it from slipping out of place, the pumping airbag can be inflated or pumped. An inflated airbag fills the space, allowing the gastric tube to come into closer contact with the stomach wall, thereby reducing the likelihood of movement. Conversely, pumping the airbag can clamp the stomach wall by reducing the volume of the airbag, which also helps to immobilize the gastric tube.
2. **Reduced Discomfort:** The presence of a pumping airbag helps to reduce the movement of the gastric tube within the stomach, thereby reducing patient discomfort. Without an air bag or proper immobilization, the gastric tube may cause irritation or pain inside the stomach.
3. **Food and Fluid Flow Control:** In some cases, the gastric tube is used not only to empty the contents of the stomach, but may also be used to feed or instill fluids. By adjusting the status of the pumping bladder, the healthcare provider can control the position and flow of the gastric tube to suit the patient's needs.
It is important to note that the use and operation of medical devices should be performed by a healthcare professional to ensure safety and effectiveness. The use of a gastric tube, and the suction bladder within it, requires the guidance and supervision of a physician or healthcare professional to avoid potential complications or adverse events. If you or others need information about the use of a gastric tube, consult a healthcare professional.
