A squeeze is a pressure related injury that occurs when the pressure inside of an air space is greater than the outside pressure.
Check the steps you should attempt if you can not equalize.
Descend quickly until the pain passes.
Ascend until your ears are comfortable.
Pinch your nose and gently blow. Wiggle your jaw. Try swallowing.
Signal your buddy that something is wrong.
Stop your dive and plan for diving on another day.
SCUBA diving's MOST important rule is
always dive with a computer.
eat a healthy meal before entering the water.
take small sips of air.
never hold your breath.
Check all situations that will make your air last longer.
Fin quickly while swimming against the current.
Breathe slow, steady breaths.
Choose deeper dives.
Stream line your equipment, use proper weighting, and perfect your buoyancy skills.
Find the true statement about buoyancy.
If an object weighs less than the water it displaces, it is neutrally buoyant.
If an object weighs less than the water it displaces, it is positively buoyant.
If an object weighs the same as the water it displaces, it is negatively buoyant.
If an object weighs more than the water it displaces, it is exponentially buoyant.
The buddy system is partnering up with another diver or a group of divers to plan dives, assist each other with gear, manage safety concerns, and have fun together.
