Is cyanosis, blue nail beds, an emergency with asthma?

---

My husband has asthma. He has been having to use his rescue inhaler a lot more lately. Now, his fingernail beds are blueish. Is this a medical emergency, or can he wait to see his primary tomorrow?
if this is happening it would be a good idea to take him to an emergency room near you. it means that he is not getting enough oxygen in his blood. i would not wait to see the doctor tomorrow they will be able to help him now.  (+ info)

any docs out there see peripherial cyanosis before cardiac arrest?

---

I have to say I disagree with the previous answerer because your question did not bring up CHF, as he elaborated on. Almost all who go into cardiac arrest for any reason show some signs of peripheral cyanosis first. Not all, but most. FYI: it's not doctors who usually are the first responders, or the ones who find people in cardiac arrest. It's the clinicians at the bedside--predominantly nurses. Doctors are relative late comers to cardiac arrest scenes, as a rule. They run to the scene after the nurse has found the patient in cardiac arrest, called the code and started the resuscitation process.  (+ info)

Why cyanosis in crying infants?

---

Why does cyanosis / bluish discolouration of lips and toungue occur in infants when they cry breathlessly?
cyanosis occurs due to the lack of oxygen. They are not getting sufficient oxygen and therefore the blood is a bluish hue instead of the nice bright red it is when properly oxygenated.  (+ info)

Why is cyanosis a classical sign of a heart defect?

---

Cyanosis is a sign that a person is not getting oxygenated blood to their system, that's all. It's not so much a sign of a heart defect so much a sign that oxygenated blood is not present. There could be many reasons for this.  (+ info)

What causes cyanosis (blueness) in feet?

---

My feet are staying cold and blue all the time, I have a mild form of hypogylcemia but my feet were not staying blue when i was diagnosed with that. I know its poor blood circulation or poor oxygen supply in my blood, but what causes it and what can i do to fix it?
It's caused by inadequate blood flow, for which there are many causes. Peripheral vascular disease, diabetes mellitus, raynaud's phenomenon, Buerger's disease, etc. are all potential causes. You should have a doctor examine your pulses. He/she may order a Doppler ultrasound to evaluate your arteries. If that doesn't help, an MRA or CTA would be the next best step.

Your question implies that this is a long-term, ongoing problem. However, if you ever develop a cold, blue extremity acutely (all of the sudden), that is an emergency and you should go to an emergency room. The earlier you go, you may potentially be cured by an interventional radiologist relatively non-invasively. The alternative is surgery. If you don't get attention in time, you can lose your limb.

If you have something chronic, an interventional radiologist can sometimes do angioplasty (widening up your arteries with a balloon) and/or stenting (putting a wire mesh to hold them open) to improve blood flow to your feet.

If it's acute from a blood clot or thromboembolism, they can do thrombolysis (clot busting medicine), thrombectomy (physically removing the clot), and also angioplasty & stenting.  (+ info)

what is cyanosis?what does its presence indicate?

---

a nurse tell a doctor that a patient is cyanotic.
Cyanosis is a bluish coloring of the tip of the nose, around the lips and the nail beds which is an indicator of a lack of oxygen.  (+ info)

how does cyanosis lead to a heart attack?

---

Cyanosis is a term used to describe the color (usually a blue or purplish tint) of the skin due to hypoxia (lack of oxygen in the blood).
A heart attack (myocardial infarction) is when the heart muscle dies due to lack of oxygen, or lack of blood flow that transports oxygen to the heart muscle.
In other words, cyanosis doesn't cause a heart attack, but can mean heart damage is occurring. Lack of oxygen in the blood means less oxygen is getting to your heart muscle, which can cause a heart attack.  (+ info)

If someone had cyanosis would you definitly know it?

---

I keep thinking that my son is purple around the mouth but then I am like "no you are just imagining things" so I just wondered if you would definitly know if someone had that
I would not waste time, make an appointment for your son to go to the medical doctor as soon as possible. Only a medical doctor can tell you exactly what is happening.  (+ info)

can cyanosis come and go in children?

---

can cyanosis come in go in children or are the children that have it a constant blue color
It can come and go. Look up "tet spells" on the web and you'll learn about Tetralogy of Fallot.

If you are cyanotic because you are choking on something, it isn't going to go away unless you do something about that.  (+ info)
