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.

I've been dealing with Covid for 18 days and I'm on treatment right now. I'm still running a fever around 99.1 and feeling a bit of breathlessness. My doctor decided not to go for a CT scan due to the risks and put me on Foracort 400. Should I be asking my doctor if a CT scan might be necessary at this point?

no need

I'm really worried about my mom. She seems to have some sort of lung issue because she's feeling fatigued a lot and has trouble breathing even just walking short distances or using the stairs. She had pleural effusion about three years ago, and now the symptoms seem to be coming back. Can you suggest what tests she should get to figure out what's going on?

Sputum for AFB,microscopy and x-ray chest is advised to the patient.
