Understand BJJ choke mechanics: blood chokes vs air chokes, carotid compression and why chokes are safer than joint locks.
Understanding how and why chokes work makes you better at applying them — and better at defending them. This guide covers the physiology of strangulation and the mechanical principles of the highest-percentage chokes.

Blood Choke vs Air Choke
| Type | Target | Finish Time | Sensation |
|---|---|---|---|
| Blood choke | Carotid arteries | 8-14 seconds | Pressure, then unconsciousness |
| Air choke | Trachea / windpipe | 30-60+ seconds | Pain, panic, difficulty breathing |
Why Chokes Finish Faster Than Joint Locks
- Joint locks require progressive damage before submission — the person must choose to tap.
- Blood chokes work automatically — unconsciousness happens whether the person taps or not.
- This is why chokes are considered the highest-percentage finishing positions in grappling.
Choke Application Principles
- The forearm (radial bone) is the ideal pressure point — not the wrist or hand.
- Get the choke deep before closing: a shallow choke will push blood through the veins, reducing effectiveness.
- Squeeze shoulders together rather than using arm strength to maximise carotid compression.
Frequently Asked Questions
What is the difference between a blood choke and an air choke?
A blood choke compresses the carotid arteries, reducing blood flow to the brain, causing unconsciousness in 8-14 seconds. An air choke compresses the trachea (windpipe). Blood chokes are faster and more reliable — air chokes are painful but slower to finish.
Why do people go to sleep from chokes in BJJ?
When carotid arteries are compressed, blood flow to the brain drops rapidly, causing unconsciousness. This is called cerebral hypoxia. It is temporary and safe when released quickly — the brain recovers in seconds.
Is it dangerous to choke someone unconscious in BJJ?
A properly applied blood choke that is released immediately upon tapping or unconsciousness is not considered dangerous. The key is to release immediately — extended strangulation can cause harm.
