潜水如何保护耳朵

1、潜水保护耳朵的方法有耳压平衡的保持和做鼓气平压

1.1、耳压平衡的保持:瓦沙雨氏操作,用右手大拇指与食指将鼻子完全捏住紧闭后,用力向鼻子吹气,此时因鼻孔紧闭,空气便流向耳咽管,力量够大时就可以打开耳咽管,让空气进入中耳以平衡压力。但是当鼓气压力过小或鼻孔未紧闭产生漏气时,耳咽管因压力不足就不容易打开;若鼓气太过用力,会因中耳压过大而对中耳造成损伤,也会增加内耳淋巴液的压力,造成内耳挤压伤害。因此此方法慎用。

1.2、做鼓气平压:做耳压平衡时,不能太过用力或持续太长的时间作鼓气,否则造成耳朵损伤。若潜水者下潜时不做鼓气动作,则耳膜会水肿、充血,最后至耳膜向内性的凸破;破裂后,水进入中耳达成压力平衡,中耳挤压痛会消失,但因冷水注入中耳腔使潜不者发生恶心及量眩现象;当中耳腔内水温与体温相同时,则症状会稳定下来。海水温度较冷,过冷的海水会刺激内耳,造成潜水人员晕眩、方向感丧失,致溺水事件发生。

2、潜水保护耳朵的方法有检查耳咽管是否打开和向上看

2.1、检查耳咽管是否打开:下水之前先检查你的耳咽管是否打开,通过用力的吞咽,听耳朵里是否会发出“啪”或“咔嗒”的声响,如果听到,恭喜你,你的耳咽管属于打开状态,在下潜的时候,只用掌握正确的耳压平衡技巧,下潜不是问题。如果没有,你并不适合这一次的潜水。

2.2、向上看:抬头向上看,这个动作可以伸展你的颈部,往往有助于打开咽鼓管。

3、潜水保护耳朵的方法有如果耳朵感到疼痛,停止继续下潜如果有问题,不要试图强行耳压平衡并继续下潜,这样唯一的结果将是气压伤。可以试着上升一点,等到耳朵痛感消失再做耳压。

潜水的其他注意事项

1、保持沟通

在潜水的过程中,与潜水员、同伴之间的沟通要做好。有效的沟通对潜水过程起到了更好的保障。在国外,并非所有的潜水员都是一带一或者一带二的简单模式,一些热门的潜水点经常会出现一个人带十几个人潜水,因此队伍的规则必须严格遵守,即便在水底出现了突发状况也能够及时找到解决的方法途径。

2、不要单独行动

去到陌生的海域潜水切忌单独行动,因为对海域的不了解,可能会有诸多隐藏的危险存在,如果单独行动很容易出现不可逆转的后果。同时,如果与同伴一起在水底时,突然发现同伴不见的情况下,一般只允许在水底继续等待或者寻找一分钟便需离开。

3、切忌随便触摸

当你在海底见到迎面而来的海龟,也许会让你想要近距离地接触一下,成群的珊瑚和可爱的热带鱼也会让你好奇地想要伸手触摸,然而这样的行为基本是不被允许的。破坏了这片海域的环境和和谐,也许下次再来就无法看到这些神奇的物种了。

哪些人不适合潜水

1、心肺疾病患者

潜水属于比较刺激的运动,心脏病患者一定不能参加,肺部呼吸不畅,患有气喘和肺部其他疾病的人也不能参加潜水,海下的水压对肺部也会形成压迫,让人无法正常呼吸,是十分危险的。

2、心血管疾病患者

糖尿病、高血压、低血压等患有心血管疾病的人最好也不要潜水,在海下呼吸的时候血浓度的比例会发生改变,使血液中血糖浓度改变,对糖尿病人来说是非常不利的,严重的还会造成休克。

3、鼻塞问题

感冒的时候鼻子被塞住了,是一定不能下水的,我们在水下本来就很难呼吸,再加上鼻塞,根本就无法正常呼吸,这是会危及生命的。

4、耳压平衡

感冒除了鼻子不通气无法呼吸,也无法做耳压平衡,在海下水压是非常大的,我们的耳朵会感到非常的疼痛,还可能出现头晕想吐的症状,所以感冒也不可以潜水。

How to protect the ears from diving

1. The way to protect the ears is to keep the ear pressure balance and make the drum air pressure.

1.1, the balance of the ear pressure balance: Shah's operation, with the thumb and index finger of the right hand and the index finger to completely pinch the nose close, blow the nose, at this time the nostrils closed, the air flow to the eustachian tube, when the strength is large enough to open the eustachian tube, let the air enter the middle ear to balance pressure. But when the gas pressure is too small or the nostrils are not closed, the eustachian tube is not easy to open because of the lack of pressure. If the drum gas is too strong, it will cause damage to the middle ear because of the excessive pressure of the middle ear, and it will also increase the pressure of the inner ear lymph, and cause the inner ear extrusion injury. Therefore, this method is used carefully.

1.2, do air pressure: when doing ear pressure balance, do not force or continue too long to make drums, otherwise cause ear damage. If the diver does not do the drumming movement, the eardrum will edema and congestion, and finally to the inward convex rupture of the eardrum; after the rupture, the water enters the middle ear to achieve pressure balance, the middle ear squeezing pain will disappear, but the cold water injections into the middle ear cavity make the dive nausea and glare phenomenon; when the water temperature is the same as the body temperature in the middle ear cavity, the symptoms will stabilize under the condition. Come on. The sea water temperature is colder, and the subcooled water will stimulate the inner ear, causing the diving personnel to feel dizzy and lose their sense of direction and cause drowning.

2. The way to protect ears is to check whether the eustachian tube is open and up.

2.1, check the eustachian tube open: before the launching of the first check your eustachian tube is open, through the hard swallowing, listen to the ears will send out "clack" or "clack" sound, if you hear, Congratulations, your eustachian tube is open, when the dive, only the right ear pressure balance skills, submergence is not asked. Question. If not, you are not suitable for this scuba diving.

2.2, look up: look up, this action can stretch your neck, often helps to open the eustachian tube.

3. The method of diving to protect the ears is that if the ears feel pain, stop continuing to dive if there is a problem, do not try to force the ear pressure balance and continue to dive, so the only result will be a barometric injury. You can try to rise a bit, until ear pain disappeared, then ear pressure.

Other notices of diving

1, keep communication

In the process of diving, communication with divers and companions should be done well. Effective communication provides a better protection for the diving process. In foreign countries, not all divers are the simple mode of one or two of the area. Some hot diving spots often show a person with more than ten dives, so the rules of the team must be strictly observed, even if there is a sudden situation in the bottom of the water, the way to solve the problem can be found in time.

2. Do not act alone

To go to unfamiliar sea diving should not act alone, because there may be a lot of hidden dangers for the sea area, and it is easy to have irreversible consequences. At the same time, if you suddenly find your companion missing when you are at the bottom with your companion, you usually only allow to wait at the bottom of the water or to leave for a minute.

3, do not touch casual touch

When you see a head-on sea turtle on the bottom of the sea, it may make you want to touch a close contact. Crowds of corals and lovely tropical fish will make you curious to reach for touch, but this behavior is basically not allowed. Destroy the environment and harmony of this sea area, maybe next time we won't see these amazing species again.

Which people are not suitable for diving

1. Patients with cardiopulmonary disease

Diving is a more stimulating exercise. Patients with heart disease must not be able to participate, lung breathing is not smooth, people suffering from asthma and other diseases of the lungs can not take part in diving. The water pressure of the sea will also form pressure on the lungs. It is very dangerous to make people unable to breathe normally.

2. Patients with cardiovascular disease

People with diabetes, high blood pressure, hypotension, and other people with cardiovascular disease should not be able to dive. The ratio of blood concentration will change when breathing under the sea and changes the blood sugar concentration in the blood. It is very bad for diabetics and severe shock.

3. The problem of nasal congestion

When a cold is stuffed with his nose, it is certain that it can't be launched. It is difficult for us to breathe under the water, and then we can not breathe properly, and it will endanger life.

4. Ear pressure balance

Cold in addition to the nose can not breathe and can not breathe, can not do ear pressure balance, under the sea water pressure is very large, our ears will feel very pain, may also appear dizzy, vomiting and vomiting, so the cold can not dive.
