Clinical observation: Beau's lines on fingernails after deep saturation dives
1Hyperbaric Treatment Center University ofHawaii, John A. Burns School of Medicine 347 N. Kuakini Street, Honolulu, HI 96817, USA.
Summary
Deep saturation diving caused Beau
Area of Science:
- Diving Medicine
- Nail Abnormalities
Background:
- Beau's lines are transverse furrows on fingernails.
- They are associated with severe metabolic stress and various medical conditions.
Purpose of the Study:
- To report the occurrence of Beau's lines in divers after saturation diving.
- To investigate a potential link between saturation diving and nail changes.
Main Methods:
- Observation of fingernails in divers post-saturation dives.
- Dives conducted at the Navy Experimental Diving Unit.
- Divers breathed a heliox-oxygen mixture and performed hard work.
Main Results:
- All 6 divers in a 1100-foot dive showed Beau's lines.
- 2 of 6 divers in a 1000-foot dive also developed Beau's lines.
- Some divers experienced decompression sickness.
Conclusions:
- Beau's lines may be a sign of physiological stress from deep saturation diving.
- This is the first reported instance of Beau's lines associated with saturation diving.
- Further research is needed to understand this phenomenon.

02:30Naturalistic Observations
If you want to understand how behavior occurs, one of the best ways to gain information is to simply observe the behavior in its natural context. However, people might change their behavior in unexpected ways if they know they are being observed. How do researchers obtain accurate information when people tend to hide their natural behavior? As an example, imagine that your professor asks everyone in your class to raise their hand if they always wash their hands after using the restroom. Chances...
01:19Handwashing II: Pre-procedure and Initial Procedure Steps
The pre-procedure steps of handwashing include removing jewelry and rolling up sleeves. However, many organizations allow staff to wear wedding rings.
The hand washing procedure itself includes the following steps. First, cover cuts, if any, on hands with a waterproof dressing. Cuts and abrasions can become contaminated with bacteria hindering the ability to clean the area thoroughly. In addition, repeated hand washing can worsen an injury. The nails must be short and clean, without nail paint...

01:05Accessory Structures of the Skin: Nails
Nails are one of the important accessory structures of the skin. They are hard, protective structures that cover the dorsal surface of the distal phalanges of fingers and toes. Nails are composed of specialized keratinized cells and serve various functions, including protection, sensation, and manual dexterity.
The main components of a nail include the following.
Nail Plate: The nail plate is the visible portion of the nail that extends beyond the fingertips or toes. It is a hard, translucent...

01:29Assessment of the Cardiovascular System II: Inspection
Inspection is the initial step in assessing the cardiovascular system. It involves a detailed visual examination that provides crucial information about a patient's circulatory and cardiac health. This systematic process, conducted from head to toe, helps identify signs of cardiovascular conditions by observing physical appearance, skin and mucous membranes, jugular and carotid pulsations, chest symmetry, and the condition of the extremities.
