Rescuers can ensure they provide effective breaths using a bag-mask device by following these key steps:
- Position the mask properly over the patient's nose and mouth, ensuring it covers both areas completely.
- Use the C-E grip technique to create a secure seal: form a “C” shape with the thumb and index finger on top of the mask and an “E” shape with the other three fingers lifting the jaw to keep the airway open.
- Gently squeeze the bag over about 1 second to deliver a controlled breath.
- Observe for visible chest rise with each breath, which confirms that air is entering the lungs effectively.
- If the chest does not rise, reposition the mask and patient's head to improve the seal and airway alignment.
- Avoid delivering breaths too quickly or forcefully to prevent lung injury; breaths should be steady and sufficient to cause chest rise.
- Whenever possible, use a two-person technique: one person holds the mask using the proper grip for a better seal, while the other squeezes the bag.
Regular training and practice in these techniques are important to maintain skill and confidence in providing effective ventilation during emergencies.
