What are the breathing methods of diving?

Underwater breathing is the first problem in learning scuba diving. I believe that the fear of breathing underwater for the first time is still fresh in many people's memories. Then, what knowledge and skills should divers learn about underwater breathing? The following homepage tells you what you should know about underwater breathing to improve your skills.

One: Take a deep breath and vomit slowly.

Use time:

Whether in the water or on the water, it is suitable when there is a lot of exercise, even when you are nervous, panicked, short of breath and breathless.

After diving to the bottom of the water and establishing neutral buoyancy, you must keep a continuous long stream of deep breathing and slow vomiting in order to swim in the beautiful new world under the sea!

Note: Some people use natural respiration on land, but what is the effect? Only when you know yourself well!

Action essentials:

When inhaling, stick the tip of your tongue to your mouth, leaving only a little gap, and slowly inhale to the abdomen (that is, the lower abdomen). Press the lower abdomen with your hand and feel bulging, that is, force the diaphragm to descend and make oxygen reach the deep tissue. Please don't inhale a lot of air with chest breathing (natural breathing on land), because the sternum is compressed, you can't absorb more air, and the air inhaled into the lungs can't stay for a long time, which will make beginners feel chest pain and chest tightness every other day!

When exhaling, put the tip of your tongue against the bite, leaving only a gap. Don't push hard, exhale slowly. If you want to breathe in, you can spit it out all at once, and don't try to spit it out slowly. In this way, breathing according to the essentials is still based on the principle of softness and comfort.

Don't hold your breath intermittently! ! !

Take a deep breath and spit slowly. On days when you don't dive, you can always find opportunities to practice a natural reflex action, and your breathing will be smooth after entering the water. Don't think that there is no reward for practicing after entering the water, and you will be breathless after three breaths!

When practicing deep breathing and slow vomiting for the first time, you can gradually inhale for ten seconds and spit for ten seconds, and then increase it to inhale for twenty seconds and spit for twenty seconds until you can inhale for thirty seconds and spit for thirty seconds. If you take chest breathing, you can only inhale and vomit for two seconds at a time.

Two: shallow inhalation and long vomiting method

Use time:

Used when diving from the surface or water to the bottom.

Action essentials:

What is shallow suction? That is, it is like breathing on land, but after deliberately inhaling only half a breath, it is immediately changed to 10~30 seconds of long exhalation.

What is long vomiting? Breathe out continuously until your chest sinks (adjective), which makes you feel like vomiting.

There are many reasons why novices can't dive, but the main reason is that the air in BCD is not exhausted, and the breathing method of inhaling and exhaling suddenly is adopted.

Three: continuous exhalation "blare" method

Use time:

Used to control emergency swimming or buoyancy rise, and when the auxiliary head falls off and is recovered.

Action essentials:

Stick out your tongue against the bite of the secondary head, leaving only a small gap, or protrude your lips into a sharp shape. The more pointed the better, the two sides of the tongue are rolled up and inward, and the tip of the tongue is attached to the lips, leaving only a small gap. When exhaling, remember to make a continuous beep. Don't hold your breath and don't interrupt the beep. When exhaling, be gentle, not hard. All the ways of exhaling still have the feeling of slightly exerting force on the abdomen, but don't deliberately exert force.

The purpose of "whoosh" is to ensure that every student is in a state of continuous exhalation and will not inhale through the nose. It can also help the coach to observe who doesn't exhale continuously, and it can also help the students to transfer their fear of choking water and increase their interest in practice.

Some people don't agree with this practice, but personally think that as long as it is beneficial to students, it can shorten the time of self-experience and let them learn quickly. Why not?

Four: nasal "um" exhalation method

Use time:

Mirror drainage, mirror flat pressure, especially suitable for beginners who are afraid of water or people with small lung capacity who don't know explosive exhalation.

Action essentials:

Inhale deeply first, press the tip of your tongue against the mouth of the call tube or secondary head, and spit it out without leaving any gap. Of course, your lips should also be clenched to prevent air leakage. Start slowly raising your head, exhale slowly and continuously with a little force through your nose, and make a "hmm" sound. At this time, the nose has a vibrating feeling of exhalation.

Why do you make a "hmm" sound? Usually, a beginner always thinks that his mouth has been closed according to the coach's instructions when doing drainage, but in fact, he can't adapt to it because of biting his mouth, which will naturally lead to air leakage. Moreover, the coach ignores the observation and only repeatedly demonstrates and asks for repeated actions, which will aggravate the frustration of students' failure and suffocation. The sound of "hmm" ensures that students can never exhale through their mouths and noses at the same time! You can try it right away if you don't believe me.

Yes, the coach taught beginners explosive exhalation from the beginning (it is easy to do under pressure in water). Unless you are not afraid of water, it will only increase the psychological burden of students who are afraid of being choked by water, lengthen the learning progress and consume a lot of valuable teaching time of coaches. It's really a lose-lose!

Explosive exhalation is not unteachable. According to personal experience, nine times out of ten novices can't drain water smoothly at one time.

When practicing in the water, the coach can listen to the students' "hmm" voice, and can see whether bubble flow comes out of each student's mouth when draining water, so as to know who can't do it well!

It is suggested to practice on the shore first, and let the students pour water in the mirror to practice (or practice at home) drainage. This has many advantages. Students will not be distracted by fear of losing their balance in the water and choking their noses. After they have the experience of land drainage, they won't panic when they get into the water. Moreover, mirror drainage skill is one of the tips for students to learn diving, and it is also a weapon to help students eliminate their fear of water!

Five: explosive expiratory method

Use time:

On the surface or in water, the mirror is used for drainage and pressure relief, and the surface breathing tube is used for drainage. It is also suitable for lifeguards who don't wear floating tools to float on their backs, tread water and swim with jellyfish.

Action essentials:

Inhale deeply into the abdomen first (the abdomen should feel a little bulging), and spit it out with the tip of your tongue against the breathing tube or the mouth of the deputy head.

The lips are also tight, so there is no gap. The tighter the lips, the better. The air concentrated in the abdomen is forced out. At the moment of exhaling, the tongue retracts, creating air rapidly and massively.

Six: turtle breathing method

Use time:

Underwater roaming, top neutral buoyancy, water layer suspension, photography, cave sinking diving.

Action essentials:

The older generation of divers also called this method "sucking half mouth and spitting half mouth". Anyway, the most important requirement is that the whole body must be thorough. & gt relax >>& gt relax again >>> completely relax >>& gt& gt achieve the same intention, forget yourself and look in the mirror and you will succeed! ! !
