can cyanosis, blue nail beds occur when a person dies instantly?


My son was killed in a car accident. The medical examiners office reported cyanosis, blue nail beds, and said he lived for 30 minutes after the accident on the death certificate. The first man on the scene of the accident reported that my son was killed instantly. So I need to know, can cyanosis, blue nail beds occur when a person dies instantly?
----------

Cyanosis will always occur after death due to the cessation of circulation. The first person on scene often can't determine time of death. I'm an EMT. In order to determine an approximate time of death, someone trained in that field will have to examine the body. I'm very sorry for your loss. My heart goes out to you. Stay strong.  (+ info)

What disease could cause cyanosis, increased aggression, and delusion?


I need an answer for a writing project, I'm working on. Thank you.
----------

It's possible that some one who has had a certain kind of brain trauma can exhibit cyanosis, aggression & delusional behavior. I know that I've dealt with this. No need to say "increased" aggression because we shouldn't be aggressive to begin with.

Respiratory acidosis or an acid-base imbalance can cause cyanosis and aggression, possibly delusions such as perceived threats. These are conditions not diseases. COPDs like emphysema, severe asthma, chronic bronchitis and neuromuscular diseases can cause respiratory acidosis . Necrotizing enterocolitis causes acid-base imbalances.  (+ info)

Why does cyanosis occur when affected by hypothermia?


I have an a&p assignment due in for tomorrow and I'm really stuck :( I'm not looking for people to do the work for me, I just desprately need an answer - fast! Please lads, I'm stuck in a rut :(
----------

Blood rushes to the internal organs where it is needed the most. - Brain, heart, lungs etc. This causes peripheral shutdown and the clinical sign of cyanosed peripheries....blue hands and feet.  (+ info)

What are the PaO2 Scores for mild/moderate/severe cyanosis when tested on a ABG.?


I ask because different text books have different answers. Some just say that the normal AaO2 is 80 to 100; but others say 80 to 95; what are the exact boundaries between mild to moderate and moderate to severe cyanosis?
----------

Well different textbooks will always have different normals. My normal value that I use is a PaO2 of 80-100mmHg.

Mild Hypoxemia is a value of 60-79mmHg
Moderate Hypoxemia is 40-59mmHg
Severe Hypoxemia is any value <40mmHg

Normal SaO2 (pulse ox) is 95-100%

Cyanosis occurs as a result of a drop of at least 5g/dL of oxygenated hemoglobin in the blood.  (+ info)

Is Cyanosis curable or can it be avoided in long term?


Will the person always have the bluish colour or can normal skin colour return in the long run?
----------

Cyanosis is a physical sign causing bluish discoloration of the skin and mucous membranes. Cyanosis is caused by a lack of oxygen in the blood. Cyanosis is associated with cold temperatures, heart failure, lung diseases, and smothering. It is seen in infants at birth as a result of heart defects, respiratory distress syndrome, or lung and breathing problems.

Description

Blood contains a red pigment (hemoglobin) in its red blood cells. Hemoglobin picks up oxygen from the lungs, then circulates it through arteries and releases it to cells through tiny capillaries. After giving up its oxygen, blood circulates back to the lungs through capillaries and veins. Hemoglobin, as well as blood, is bright red when it contains oxygen, but appears dark or "bluish" after it gives up oxygen.

The blue discoloration of cyanosis is seen most readily in the beds of the fingernails and toenails, and on the lips and tongue. It often appears transiently as a result of slowed blood flow through the skin due to the cold. As such, it is not a serious symptom. However, in other cases, cyanosis is a serious symptom of underlying disease.  (+ info)

why is there an occurence of cyanosis during hypoxia?


i mean why is there occurence of being a bit blue in color, when the blood is actually red, what happens that makes it blue?
----------

Hemoglobin, which is a molecule that attaches to RBC, gives the cells its red color when it is carrying oxygen. When it is not carrying oxygen it cannot produce the red pigment and the blood appears blue.  (+ info)

What Causes a brief episode of cyanosis maybe lasting 20 seconds to a minute with palpitations and tingling ?


I experience these brief episodes . I feel very anxious when I am having one {like I am dying}. After my heart slows down and my color comes back I feel shakey for about 30 minutes. I can't relate these episodes to any particular thing they just happen and they are very frightening. If you have experienced this or know someone who has please write me . Thanks
----------

True cyanosis indicates that this part of your body is not getting enough blood. That's why it turns blue. You could have a heart problem. It is not unusual to have anxiety along with heart problems. Go to your doctor right away to determine what's going on. You should not diagnose this yourself.  (+ info)

consider a patient in respiratory arrest presenting with cyanosis.please explain why the patient is cyanotic?


Can you describe and expain the patient's aveola oxygen concentration and arterial carbon dioxide concentraton.
----------

Cyanosis is a blue coloration of the skin and mucous membranes due to the presence of > 5g/dl deoxygenated hemoglobin in blood vessels near the skin surface.

If the patient is in respiratory arrest, he/she will not be breathing and not introducing oxygen into the blood stream  (+ info)

2 year old with heart murmer and benign cyanosis?


I took my little grl who is 2 to the doctors as her lips turn blue when she is outside playing or in the bath, she had an ecg and the doctor tod me she has a slight heart murmer and benign cyanosis, I am not that sure what benign cyanosis is, is it linked to the heart murmer, does any one have any experience of this?
----------

Cyanosis, as in the color cyan. This is a technical term for turning blue due to lack of oxygen in the blood. If it is benign this means it's very slight or possibly confined to her extremities. If only her fingers and toes are blue that's not a medical emergency.

Why is this happening? When she is stressed her heart isn't quite up to the job. If she starts looking really blue tell her to lie down for a minute, and if she falls unconscious or looks like she's about to definitely get her to lie down. If she looks like she's in serious trouble she probably is and you should call the paramedics.

Also, avoid cold. People who have poor circulation due to age or diabetes are often extremely vulnerable to frostbite. Cold may also impair circulation further.

Why is the heart murmur itself happening? No idea. A birth defect perhaps? This is something you should discuss with your doctor.  (+ info)
