This was asked of ME at a recent beach diving get along. i feel this can be vital to bear in mind of overexpansion respiratory organ injuries (from associate degree uncontrolled ascent) and secondary embolism (air within the blood from abused respiratory organ tissue).
Lung over-expansion injury happens once a diver holds their breath once ascending underwater. this could be as very little as a one.5 meter ascent close to the surface.
How it happens (The technical reason)
When victimization breathing apparatus instrumentality underwater, the diver is respiration compressed gas at a pressure adequate to that of the water around him/her. this suggests the air getting into their lungs is at an equivalent pressure because the water. once the diver ascends, per law, the air expands owing to reducing fluid mechanics pressure, (the shallower the depth, the less the pressure) inflicting the lungs to over-inflate.
The respiratory organ doesn't burst sort of a balloon once over-inflated, instead it tears. but the tear itself isn't most a haul because the ensuing air getting into the tissues and blood. The results of such a rupture causes the pulmonic capillaries and alveoli to rupture mix blood and air into the lungs typically inflicting the diver to cough up blood. (A definite alert sign) The rupture may also cause one in all four injuries: Air embolism, abnormalcy, mediastinal respiratory disease, and hypodermic respiratory disease.
Why it happens (The human factor)
The most common causes of respiratory organ over-expansion injury ar panic and mental object. alternative less common causes ar choking, nausea, carelessness, and even smoking. Smoking will destroy the surface-active agent that keeps the lungs from jutting shut after they ar ventilated. this could cause the elements of the lungs to stay shut and simulate holding ones breath.
How to avoid
ne'er hold your breath whereas victimization breathing apparatus instrumentality.
Never provides a "puff" of air to a free diver once victimization breathing apparatus instrumentality underwater. The free diver might not bear in mind of the matter of respiratory organ over-expansion injury and ascend while not emotional their breath.
Avoid diving whereas having chest congestion issues (eg colds, flu's, etc).
Smokers mustn't smoke for many hours before a dive. (Good luck convincing them of that! thus don't dive if you're a significant smoker and have had a chilly or respiratory disease recently).
See a diving-aware doctor before learning to dive, and if you have got any injury to your lungs or chest, see the doctor once more. What to try to to the foremost common, and largest wake-up call of a respiratory organ over-expansion injury is forcing out blood. alternative indications embrace chest pains and issue respiration. If you believe such associate degree injury at once consult associate degree emergency doctor. If you would like to understand the nitty gritty a lot of, please ping ME at a neighborhood dive get along. All that grad school has to be used somehow! Tevis
