"HAPE is a noncardiogenic pulmonary edema.
The disease is thought to be caused by patchy
hypoxic pulmonary VASOCONSTRICTION (likely due to
local shunting response to hypoxia) with consequent
localized overperfusion combined with hypoxic
permeability of pulmonary capillary walls. These
changes result in high pulmonary artery pressure,
high permeability, and leak into the alveoli. HAPE
is quite distinct from other forms of pulmonary
edema and adult respiratory distress syndrome (ARDS)."
I just thought the above might interest you. I read
your article regarding the following Quran quote:
"[006:125] And
whomsoever it is Allah's will to guide, He expandeth
his bosom unto the Surrender, and whomsoever it is
His Will to send astray, He maketh his bosom close
and narrow as if he were
engaged in sheer ascent. Thus Allah
layeth ignominy upon those who believe not."
I am a medical student and I would say that
pulmonary
vasoconstriction is a specific response to
low atmospheric oxygen levels at high altitude. This
is notable, because other blood vessels in other
parts of the body actually undergo DILATION in
response to low atmospheric oxygen levels. The
reasoning is simple - we need to deliver MORE blood
to tissues in times of oxygen starvation because the
oxygen concentration in blood is reduced (due to
lowered intake from an oxygen poor atmosphere), and
to maintain constant oxygen delivery when the oxygen
concentration of blood is reduced, we deliver more
blood per unit time by dilating the blood vessels in
the periphery. The lungs are an exception
(specifically the pulmonary supply)....this is also
logical, think about it: we are in an oxygen poor
atmosphere, therefore we shut down the flow of blood
to certain alveoli that are not receiving a lot of
oxygen during inhalation
(to reduce
the blood supply to these alveoli, we need to
CONSTRICT those arterioles supplying them)
and we redirect blood flow to alveoli that are still
receiving oxygen - the net effect is
vasoconstriction in the pulmonary circulation.
Perhaps, it is hard to explain without you having a
knowledge of medical sciences, physiology or
anatomy. Forgive me if it is not clear.
In conclusion, I just wanted to suggest that perhaps
the Quranic quote is alluding to the fact that human
vasculature undergoes vasoconstriction specifically
in the pulmonary circulation (contrasting with the
rest of the body's vessels, which experience
vasodilation) during ascent to high altitudes.
The sensation of
chest tightness in HAPE (high altitude pulmonary
edema) is a specific result of vasoconstriction of
pulmonary vessels, resulting in increased
hydrostatic pressure within these now narrowed
vessels, causing fluid to leak from the vessels into
the lung tissues and alveoli. The resulting
pulmonary edema ("water on the lung") causes the
symptoms of breathing difficulty and chest
tightness.
Just wanted to give you my perspective on the verses
quoted. Thank you for all of your wonderful work
over the years.
Wasalaam.

Mirza.
3- The Scientific Proofs to the Noble
Quran's Divine Claims:
The following are official and objective scientific web sites on the internet that
contain scientific information that confirms the Truthfulness of the Divine Claims in the
Noble Quran.

From
http://www.ncaasports.com/skiing/story/6984986:
(emphesis below are mine)
Sten Fjeldheim, women's head coach at Northern Michigan
University and a member of the skiing committee,
said that the problem with going from sea
level to higher altitudes is the difference in pressure.
A person used to competing at high altitudes has a higher number
of red blood cells to carry more oxygen to the muscles,
while a
person coming from sea level has lesser oxygen-carrying capacity
because he or she has fewer red blood cells, he said.
Most sea-level athletes not accustomed to the higher
altitudes will feel a "severe
discomfort," he said.
"Strategically, you have to attack the course in a different
way," Fjeldheim said. "If you were to use the same sort of
rhythm and timing and aggressiveness you do at sea level as you
do at altitude, you don't last long."

High Altitude Sickness
.......
As
low-level dwellers, we are optimally equipped for existence at
normal air pressure of 760 mm of mercury, with an oxygen
concentration of 21%. With increasing altitude, the
concentration of oxygen remains the same, but the atmospheric
pressure decreases and with this the partial pressure of oxygen
falls. This means that the number of oxygen molecules per breath
is greatly reduced and this in turn reduces the amount of oxygen
available to the blood and tissues in the body. At the summit of
Mont Blanc (4807m), the highest mountain in Western Europe, the
partial pressure of oxygen is about half of that at sea level
and on the summit of Mount Everest (8850m), it is one third of
sea level pressure (See figure 2).
For climbers and trekkers at such
altitudes,
the lack of oxygen may cause illness that is
potentially life threatening.
Reports from Nepal have revealed that the mortality of trekkers
is about 14 per 100,000, with 25% of these attributed to
altitude illness.

From Dr. Harun Yahya at:
http://www.miraclesofthequran.com/scientific_85.html:
CHEST CONTRACTION WITH INCREASING HEIGHT
Human
beings need oxygen and air pressure in order to live. Breathing is made possible
by the oxygen in the atmosphere reaching the air sacs in our lungs. As elevation
rises, however, atmospheric pressure goes down as the atmosphere becomes
thinner. Therefore, the amount of oxygen
entering the blood stream declines and it becomes harder to breathe. As
the air sacs grow narrow and contract, we feel as if we cannot breathe.
If the amount of oxygen in the blood is less than the body needs, several
symptoms emerge: extreme fatigue, headaches, dizziness, nausea, and loss of
judgement. When a certain height is reached, it finally becomes impossible for a
human being to breathe at all.173
This is why we need oxygen bottles and special clothing in order to survive at
such elevations.
Someone at 5,000-7,500 metres (16,500-24,500 feet) above sea-level may faint
and go into a coma because of breathing difficulties. That explains the presence
of oxygen equipment in airplanes. There are also special systems that regulate
air pressure when planes fly at 9,000-10,000 metres (29,500-33,000 feet) above
sea-level.
Anoxia occurs when oxygen fails to reach the tissues. This oxygen deficiency
occurs at heights of 3,000-4,500 metres (10,000-15,000 feet). Some people even
lose consciousness at such elevations, but can be saved by immediate oxygen
treatment.
In the comparison made in the verse below, this physical truth, the changes
that take place in the chest with increasing height, is indicated in these
terms:
When Allah desires to guide
someone, He expands his breast to Islam. When He desires to misguide
someone, He makes his breast narrow and constricted as if he were
climbing up into the sky. That is how Allah defiles those who have no faith.
(Qur'an, 6:125)

From http://science.howstuffworks.com/space-suit3.htm:
Jet Aircraft
When jet aircraft
were developed, pilots needed pressurized flight suits to
cope with the low atmospheric pressure and
lack of oxygen at high altitudes.
Most of these suits were designed to be used only when the pressurized cabin failed. The
suits consisted of neoprene rubber-coated fabric that could inflate like a balloon, and a
more rigid fabric over the neoprene to restrain the suit and direct the pressure inward on
the pilot. Hoses were attached from the plane to the suit to provide oxygen.

High-Altitude Research a Thrill for Aerospace Corporation Engineer
By Dave Gutierrez
I grew up with the space program. The sky has always been an inspiring place to me. The
love of space brought me to The Aerospace Corporation, where I've spent 11 years
designing, building and deploying science experiments.
My involvement for the last two years in the development of an infrared system called
SHARP, the SEBASS High-Altitude Research Project, landed me in a unique and challenging
assignment last year as a payload specialist on NASA's high-altitude research aircraft,
the WB-57. It was the culmination of a childhood dream.
The vehicle holds two crew members: the pilot and the payload specialist. I began
training last March for my role as "backseater" on this unique aircraft,
performs upper-atmospheric sampling and Earth reconnaissance.
Survival Course
After receiving an extensive physical examination at NASA's Johnson Space Center in
Houston, I headed for the Naval Air Station in Pensacola, Fla., for a four-day water
survival course.
The training covered all aspects of sea survival, from aircraft ejection and water
landings under a parachute to rescue and recovery operations. I swam 75 yards in flight
gear, was shot from an ejection seat in a simulator, and was hoisted by a helicopter from
open water. The training culminated in two parasail rides, each followed by an open-water
landing, requiring me to use the skills I'd learned during the course.
I underwent physiology training for low- and high-altitude flight at Edwards Air Force
Base, where I experienced five hypobaric chamber rides which
demonstrated the effects of hypoxia (lack of oxygen) and pressure changes on the body.
Painful bloating can occur at altitude pressures above
40,000 feet. The training teaches subjects how the body reacts to
hypoxia and how to respond quickly should it occur.
Pressure Suit

research aircraft, the WB-57, at Ellington Field, Houston.

High-altitude flight--above 50,000 feet--requires the use of a fully pressurized flight
suit. The suits are similar to those worn by pilots aboard the SR-71 Blackbird and the
space shuttle during ascent. At Edwards I was fitted for my own suit and received the
requisite training.
I underwent another round of water training, this time in the pressure suit. The
highlight was a hypobaric chamber ride to a pressure altitude of more than 100,000 feet
(20 miles). The suit inflates to keep pressure around the body at about 35,000 feet, a
good compromise for breathing pure oxygen and the lack of mobility caused by the stiffness
of the suit.
While passing through 60,000 feet, water in a small
jar placed inside the chamber began boiling. This is Armstrong's Line,
the point at which
bodily fluids would begin vaporizing if no suit were worn.
I had always wondered what it would be like to wear a space suit.
It is pretty confining, and if you are at all claustrophobic, it's stressful. Other than
radio chatter, you hear only your heart beating and the sound of oxygen flowing into the
helmet during each breath.
The suits are cooled and heated with conditioned air supplied by the vehicle. It is
normal, however, to experience wide temperature variations during suitup, taxi and takeoff
as well as during the mission itself. Current mission scenarios require the suits to be
worn for up to seven hours. They are outfitted with eating and drinking ports and yes,
bathroom facilities.
Ground School, Flight Training
I spent a week in Houston last July for ground school and flight training in the
aircraft. My instructor was NASA pilot Steve Feaster, who has logged thousands of hours in
this type of aircraft.
I spent the first part of the week learning about the craft's systems and familiarizing
myself with the cockpit. The backseat area is small, roughly the size of a coach seat on a
commercial airliner. My primary responsibilities would be programming the Inertial
Navigation System (INS) and reading checklists to the pilot. My main duties would be
operating and evaluating the SHARP sensor and the special tracking system on which it is
mounted.
After programming the INS for a trip over the Gulf of Mexico toward Corpus Christi, we
took off on my first flight.

The aircraft accelerates quickly and climbs at an amazing rate. We leveled off just
below 50,000 feet and practiced several emergency scenarios. After a few hours in the air
we returned for several touch-and-go landings before completing the flight.
The next morning we suited up with full pressure suits for a high-altitude flight. I
was anxious but realized this would probably be my best opportunity to relax and enjoy the
view, not yet having to concentrate on operating the SHARP sensor.
Curvature of Earth Visible
On this flight we reached 63,000 feet. The curvature of the Earth was visible. With
more than 96 percent of the atmosphere below us, the top of the troposphere was visible as
a bluish-white arc on the horizon. The sky above was dark, like a normal sky about 30 to
40 minutes after sunset.
My final flight was a checkout ride to 50,000 feet, where I applied all of the skills I
had learned during my week of training. We simulated engine loss scenarios, hydraulic
failures and midcourse reprogramming of the INS. I successfully completed the flight,
earning qualification as a NASA crew member and backseater for the WB-57.
The SHARP project has now entered the flight test phase. I have flown with the system
twelve times, accumulating about 40 hours in the aircraft. The aircraft operations are
becoming more natural, allowing me to focus on evaluating sensor performance and
troubleshooting anomalies.
During my last flight in November our team collected longwave infrared hyperspectral
data on more than 90 percent of the targets deployed during flight tests at Eglin Air
Force Base in Florida. Aerospace engineers Brad Johnson and Steve Hansel were instrumental
in the successful integration of the sensor during this first series of flights.
This has been the experience of a lifetime, and I'm looking forward to future flights
with SHARP aboard the WB-57.
3- Conclusion:
The Noble Quran is filled with scientific statements and notions. These
are statements of Allah Almighty describing how He created things on earth and
in the Universe. What's most amazing is that all of these scientific
statements and notions had been proven to be in
perfect agreement with science and our modern-day scientific
discoveries. Allah Almighty made the Noble Quran be Prophet Muhammad's
(peace be upon him) Everlasting Divine Miracle and proof for Prophethood.
The Holy Book certainly stood the test of time 1,500 years ago with Its
Claims, Prophecies and Miraculous language eloquence, and it does again and
again in our day today with Its overwhelming agreement with science and
discoveries that were not known to man 1,500 years ago.
Allah Almighty through His Miraculous Statements above talked about low air
pressure in space, lack of breathing oxygen, and fatal increase in fluids, gases
and temperature inside the body. This information was not known to man
1,500 years ago! Allah Almighty Said in the Noble Quran:
"We will soon show
them Our signs in the Universe and
inside their selves, until it will become quite clear to them that it is the truth.
Is it not sufficient as regards your Lord that He is a witness over all things?
(The Noble Quran, 41:53)"
Indeed, all Praise and Glory are due to Allah Almighty alone for making
the Noble Quran be the Perfect and Everlasting Miracle, for us humans, out
of all of His Divine Miracles! And may Allah Almighty send His Peace, Mercy
and Blessings upon our Beloved and Blessed Prophet, Teacher and Role Model,
Muhammad. Ameen.
