PADI Divemaster Certification Practice Exam

What is the purpose of using the RDP Table and eRDPML for dive planning?

1. To determine the effective pressure underwater

2. To calculate air tank volume

3. To avoid decompression stops by establishing no stop dives

4. To assess water temperature changes at various depths

The correct answer is: To avoid decompression stops by establishing no stop dives

The purpose of using the RDP (Recreational Dive Planner) Table and the eRDPML (electronic Recreational Dive Planner with Multiple Levels) is to facilitate safe dive planning by helping divers manage their exposure to underwater pressure and nitrogen absorption, ultimately allowing them to avoid decompression stops. These tools provide a structured way to calculate allowable dive profiles, ensuring that divers can stay within no-decompression limits, which decreases the risk of decompression sickness. By planning dives in accordance with these limits, divers can enjoy their underwater experience safely and effectively without requiring mandatory decompression stops on their ascent. This is especially important for recreational diving, where safety and freedom from additional complications greatly enhance the enjoyment of the activity.
