There have been a number of instances during which acute medical conditions have been diagnosed through crew medical training. One rather interesting case involved a young, fit and outwardly healthy student — fairly representative of all crew. Over the duration of the course the instructor reviewed some rather odd blood pressure readings from this student. After checking the readings himself, the instructor found that this student’s blood pressure was, in fact, dangerously high.
 
About 20 percent of the young adult population has hypertension, but in most instances there are no symptoms, as was the case with said crewmember.
 
By participating as a volunteer in the medical training course, the crewmember in question was able to get the appropriate diagnosis and treatment for regulating his blood pressure.
 
He also learned a lesson important for all crew: receiving regular check-ups and seeking advice from medical professionals is always important, even for seemingly healthy young adults.
 
Hypertension & High Blood Pressure
Hypertension, also known as high blood pressure, occurs when the pressure in the arteries is higher than normal.
 
Normally, a certain amount of pressure is needed to push blood through your arteries, the blood vessels that take blood from your heart around your body. Blood pressure is one of your “vital” signs. It’s measured using two numbers; first number is referred to as systolic and the second as diastolic.
 
A diagnosis of hypertension can only be made by measuring your blood pressure several times and finding the measurement to be consistently high. Hypertension is diagnosed when either the systolic and/or diastolic readings are above “normal.”
Normal – Below 120/80 mmHg
Pre-hypertension – Between 120-139/80/89 mmHg
Hypertension – Equal to or above 140/90 mmHg

Uncontrolled high blood pressure damages your arteries. Over time, this damage causes poor flow, harming major organs and resulting in “end organ” damage such as
• heart failure;
• kidney failure;
• eye problems with loss of vision;
• stroke.
 
Diagnosing and managing hypertension can prevent this damage.
 
Ways to prevent hypertension include
• eating a healthy diet;
• being physically active;
• managing your weight;
• avoiding tobacco smoke;
• watching your salt (sodium) intake;
• limiting alcohol intake.
 
How is hypertension treated?
The initial treatment of hypertension involves the same simple, healthy lifestyle choices for prevention. If your blood pressure is still high after making lifestyle changes, most doctors will prescribe medication; regular check-ups will be necessary to ensure blood pressure lowers.
 
World Heart Day is September 29. Be sure to check your blood pressure and
celebrate healthy hearts.

Out of curiosity what is the likelihood of someone with hypertension getting an unrestricted ENG1? What kind of restrictions are likely to be placed on such an individual?
