Select a bag that allows full lung expansion during manual ventilation — size matters for safety and effectiveness.

Using a smaller bag reduces resistance and makes spontaneous breaths easier to observe in small patients.

Small bags for small patients, large bags for large ones — keep it simple, and always size appropriately.

Choose from 0.5L to 5L. Need help? View or download our full Breathing Bag Size Chart to select the right fit.

Choosing the correct breathing bag size is critical for safe and effective ventilation. This guide offers general recommendations based on estimated patient size and tidal volume.

These are estimates. The premise is to try to approximate bag size to lung size. Selecting the right size helps ensure adequate lung inflation, reduces resistance, and improves visibility of spontaneous breathing — especially in smaller patients.
