Equalisation Tecniques


As a SCUBA diving instructor, one of the most important lessons I teach my students is the proper technique for equalising their ears and sinuses during a dive. The equalisation is the process of adjusting the pressure inside the ears and sinuses to match the surrounding water pressure, and it is essential for preventing painful and potentially dangerous barotrauma.

There are several techniques that divers can use to equalise, and the most effective one will depend on the individual diver's anatomy and preferences. Here are some common techniques and my personal experience with them:

  1. The Valsalva Maneuver: This is probably the most well-known technique, and it involves pinching the nose and blowing gently through the nostrils to equalise the pressure in the ears. Some divers find this technique uncomfortable or ineffective, especially if they have nasal congestion or small nostrils.
  2. The Toynbee Maneuver: This technique involves pinching the nose and swallowing to equalise the pressure in the ears. Some divers find it easier to swallow than to blow through their nostrils, and it can also help to clear the sinuses.
  3. The Frenzel Maneuver: This technique involves pinching the nose and making a "k" sound with the back of the throat to equalise the pressure in the ears. It requires practice and can be difficult for some divers to master, but it is very effective once you get the hang of it.
  4. The Lowry Technique: This technique involves pinching the nose and using the muscles in the mouth and throat to push air into the ears and sinuses. It is similar to the Frenzel Maneuver but requires less precise control of the throat muscles.

Regardless of which technique a diver uses, it is important to equalise frequently and early in the dive. This will prevent the pressure from building up and causing discomfort or pain. It is also important to communicate with your diving buddy and pay attention to any signs of barotrauma, such as pain, dizziness, or hearing loss.

In my experience as a SCUBA diving instructor, I have found that the most effective equalisation technique is the one that works best for the individual diver. It is important to experiment with different techniques and find what works best for you. With practice and patience, you can master the art of equalisation and enjoy comfortable and safe diving.

Posso trasportare le mie bombole in auto? La risposta e'...

...ovviamente si! ma vediamo come e' disciplinato l'argomento e se ci sono accorgimenti particolari da tenere in considerazione. Nella mia macchina privata Un subacqueo può arrivare al sito di immersione in automobile e portarsi la bombola con aria compressa o nitrox, l’ossigeno di emergenza, l’argon per la muta stagna. Un privato che trasporta bombole subacquee caricate con aria, nitrox o argon per motivi personali (es. immersioni ricreative o ricariche) non è tenuto ad avere alcun documento di trasporto né etichette sul veicolo o sulla bombola. Deve solo trasportare la bombola in sicurezza nel portabagagli o sul pavimento del veicolo. La bombola non deve stare in posizione verticale ma incastrata tra i bagagli o dietro ai sedili per non farla rotolare di qua e di là. Su una macchina aziendale Le norme per le  aziende del settore subacqueo  sono diverse da quelle per i privati. C’è un limite di 1000 litri di volume totale di bombole di aria, nitrox, ossige...

Perchè li chiamiamo "BENDS"?

Immagine
In italiano sarebbe "La malattia dei cassoni", più comunemente definita come "Bends". Ma da dove deriva questo nome? La storia ci riporta agli inizi del '900, periodo nel quale operai dragavano il fondo di laghi, fiumi ed il mare con questi grossi cubi immersi in acqua e riempiti di aria compressa. Questi Cassoni avevano un grosso tubo nella parte superiore, denominato "camino" nel quale vi erano le scale per l'accesso alla parte immersa e per il pompaggio dell'aria compressa. Nella parte superiore vi era, di solito, una camera di compensazione. Il fondo invece era aperto per permettere la lavorazione. Come è semplice intuire, pur inconsapevolmente, tali operai erano del tutto soggetti alle stesse leggi che regolano l'attuale subacquea e quindi anche alla Malattia da Decompressione. Nel loro caso specifico, repentini cambi di pressione inducevano alla formazione di bolle nei tessuti dell'organismo, e proprio in quel periodo l...

Understanding the Forces of the Ocean: Current, Surge, Tide, Wave, and Swell

Understanding the Forces of Ocean Currents Ocean currents are dynamic and powerful forces that shape our planet's oceans, influencing everything from climate patterns to marine life migration. At the heart of understanding ocean currents lies a complex interplay of various factors, including wind, temperature, salinity, and Earth's rotation. In this article, we delve deep into the mechanics behind ocean currents, exploring their origins, types, and impact on global ecosystems. Origins of Ocean Currents Ocean currents are primarily driven by two main factors: wind and density gradients. Surface currents, also known as wind-driven currents, are primarily influenced by the frictional drag of the wind on the ocean's surface. As winds blow across the water, they transfer their energy to the surface, creating movement and generating currents. These surface currents can travel vast distances and play a crucial role in redistributing heat around the globe. Below the surface, densit...
