The VPM (Varying Permeability Model) and the BUHLMANN model in SCUBA diving planning

Scuba diving is a popular recreational activity that allows people to explore the underwater world. However, it is a dangerous activity that requires proper training and equipment to ensure the safety of the divers. One important aspect of diving is the calculation of dive profiles, which involves determining the amount of time that a diver can safely spend at different depths. There are two main models used for calculating dive profiles: the VP M (Varying Permeability Model ) and the BUHLMANN model. Both models are used to predict the maximum operating depth (MOD) and the no-decompression limit (NDL) for a diver. The VPM model was developed by Dr. Bill Stone and Dr. Pete Ekstrom in the 1980s. It is based on the idea that the permeability of gases in the body changes with depth and time. The model takes into account the effect of tissue compartments on the absorption and elimination of gases, and it predicts the risk of decompression sickness (DCS) based on the diver's dive profil...

Never overestimate your abilities - the "Dunning-Kruger" effect

Exploring the mesmerizing underwater world through SCUBA diving is a thrilling adventure, but it comes with its share of challenges and risks. One psychological phenomenon that can significantly impact the safety of divers is the Dunning-Kruger effect. Named after psychologists David Dunning and Justin Kruger, this cognitive bias can lead divers to overestimate their abilities, potentially putting themselves and others in harm's way. Understanding the Dunning-Kruger Effect: In 1999, Dunning and Kruger conducted experiments revealing a pattern: individuals with limited skills tended to overestimate their proficiency, while those with greater expertise often underestimated their abilities. In the context of SCUBA diving, this translates to novice divers thinking they are more capable than they truly are, while experienced divers may downplay their skills due to a deep understanding of the complexities involved.
