Which Action Can Rescuers Perform to Potentially Reduce the Risk of Gastric Inflation?

Gastric inflation is a common concern during cardiopulmonary resuscitation (CPR) and can lead to serious complications. It occurs when air enters the stomach instead of the lungs during rescue breaths. Rescuers must be aware of this risk and take appropriate actions to minimize gastric inflation. Here are some actions that can potentially reduce the risk:

1. Proper head positioning: Rescuers should ensure the head is properly tilted and positioned to maintain an open airway. This helps to direct the airflow towards the lungs rather than the stomach.

2. Effective mouth-to-mouth technique: Rescuers should deliver gentle breaths by firmly sealing their mouth over the victim’s mouth, ensuring a tight seal. Blowing too forcefully can increase the risk of gastric inflation.

3. Use of a barrier device: Utilizing a barrier device, such as a pocket mask or face shield, can provide an extra layer of protection. It not only helps to prevent the direct contact of saliva but can also assist in delivering effective breaths.

4. Proper compression-to-ventilation ratio: Maintaining the recommended compression-to-ventilation ratio of 30:2 during CPR is crucial. This ensures that the focus remains on providing adequate chest compressions, reducing the chance of excessive ventilation.

5. Avoiding excessive ventilation: Over-ventilation can lead to gastric inflation. Rescuers should be cautious and deliver breaths at an appropriate rate, allowing for full chest recoil after each compression.

6. Continuous monitoring: Constantly monitoring the victim’s chest rise and fall during rescue breaths can help rescuers assess the effectiveness of their technique. If they notice excessive abdominal rise, they can adjust their delivery technique accordingly.

7. Training and practice: Regular training and practice in CPR techniques are essential for rescuers. By staying updated on the latest guidelines and practicing proper techniques, they can effectively reduce the risk of gastric inflation.


Q1. What are the potential complications of gastric inflation during CPR?
A1. Gastric inflation can lead to regurgitation, aspiration, and subsequent lung damage.

Q2. Can gastric inflation be completely avoided during CPR?
A2. While it is not always possible to avoid gastric inflation entirely, following proper techniques can significantly reduce the risk.

Q3. Is gastric inflation more common in certain age groups?
A3. Gastric inflation is more likely to occur in infants and children due to their smaller airways.

Q4. Are there any signs or symptoms of gastric inflation?
A4. Excessive abdominal rise, belching sounds, or regurgitation may indicate gastric inflation.

Q5. What should rescuers do if they suspect gastric inflation?
A5. Rescuers should reposition the victim’s head, ensure a proper seal, and adjust their ventilation technique if necessary.

Q6. Can using an advanced airway device reduce the risk of gastric inflation?
A6. Yes, advanced airway devices, such as endotracheal tubes or supraglottic airways, can help reduce the risk by providing a more secure seal and better control of ventilation.

Q7. Are there any medications that can help reduce gastric inflation?
A7. No specific medications are available to directly reduce gastric inflation, but administering medications for underlying causes, such as epinephrine for anaphylaxis, can help stabilize the patient and minimize the risk.
