潜水医疗健康要求

水肺潜水要求最低程度的健康和身体素质良好。 如果存在慢性健康不良状况,食用某些药物和/或近期手术可能需要你在潜水前获得医生的书面批准。

为避免失望,请下载并查看潜水员医疗健康调查表 Diver Medical From,以确保在注册水肺课程之前不需要获得医生的批准就能潜水。 教练,潜水长和潜店工作人员不是医师,不应征求他们的医疗意见; 只有医疗专业人员才能提供医疗许可以潜水。

如果你(或你的医生)对潜水的健康状况有疑问,请与Divers Alert Network(DAN)的专家联系。

Choose a dive shop close to home to:

  • Support your local diving community
  • Meet dive buddies in your local area
  • Learn about your local ecosystem

其他费用和装备

This course requires both knowledge development and in-person training for certification. 

  • When you purchase the PADI eLearning course from our website, the cost covers the knowledge development portion only.
  • There is an additional cost to complete your practical training with a PADI Instructor. Please contact your PADI Dive Center or Resort for pricing. 

If you do not own a set of scuba equipment, and you would like to make the two optional dives, you will need to rent gear. 

If you own scuba gear, confirm it can be used with nitrox (don't worry, most modern dive equipment is compatible). If you don't have the manuals that came with your equipment, your PADI Dive Shop or Instructor can help.

Only certain scuba tanks can be filled with enriched air (you'll learn more about this in the course). Your PADI Dive Shop will provide dedicated nitrox cylinders for your enriched air dives. Your instructor will also provide an oxygen analyzer.

 
时间承诺

PADI eLearning: 2-4 hours

Entire course: 1-2 days

It's possible to earn your nitrox certification in just one day. Simply complete the online course and schedule a short practical session with your instructor. The two dives are optional. You can also earn a nitrox certification simultaneously with another course. After completing Enriched Air eLearning and the practical session with your instructor, you can use nitrox while completing dives for your Advanced Open Water Diver certification, Peak Performance Buoyancy certification, etc.

此课程之后

If you're interested in staying underwater for an extended period, experiencing close-up animal encounters, or exploring places few divers ever see, ask your instructor about technical or rebreather diving.

  • Technical diving allows you to dive beyond recreational "no stop" limits. Stay at a shallow depth for hours, or plan dives beyond recreational dive limits.
  • Rebreathers, simply put, save and recycle your breathing gas. This allows you to stay much longer underwater. Rebreathers emit little to no bubbles, so you can get closer to wildlife that might run away from the noisy bubbles of an open circuit system.
