The four types are as follows: (1) the hypoxemic type, in which the oxygen pressure in the blood going to the tissues is too low to saturate the hemoglobin. (2) the anemic type, in which the amount of functional hemoglobin is too small, and hence the capacity of the blood to carry oxygen is too low. (3) the stagnant type, in which the blood is or may be normal but the flow of blood to the tissues is reduced or unevenly distributed. (4) the histotoxic type, in which the tissue cells are poisoned and are therefore unable to make proper use of oxygen.

Can you help me figure out my PFT report? I've been told I have allergic bronchitis. My x-ray and sputum culture look normal, and I used to smoke but quit. Right now, I'm mainly dealing with throat irritation, coughing, and nasal congestion, but no fever or trouble breathing. What can I do to keep these symptoms from coming back? I'm using kastilex ab tablets and furamist spray. Any advice would be great!

I've had a persistent cough for the past three years along with frequent throat infections and mouth ulcers. I recently had sinus surgery, but the cough hasn't gone away. What could be causing this, and is there anything else I should look into?

Also called upper airway cough syndrome, postnasal drip is a common cause of a long-lasting cough. Allergies, viruses, dust, chemicals, or inflammation can irritate your nasal membranes and trigger runny mucus that drips out of your nose and down your throat. This makes you cough, especially at night when you lie down
