North American Rescue Hyfin Vent Chest Seal, 2 Count
Product Description
The new hyfin vent chest seal design provides 3-vented channels that prevent airflow into the chest cavity during inspiration while allowing air to escape through the vent channels during exhalation. The 3-vent channels allow blood to escape and also provide a backup fail-safe system, as even if two of the three channels become obstructed, the vent will remain fully operational.
