### output:

Hi, With the blood reports awaiting, the doctor must have asked to perform this because they are trying to find any abnormalities in the blood which is leading to cold feeling. Usually this doesn't happen but if any kind of changes in blood is found than it will be directed accordingly towards the treatment part.  Talking about your asthma, you should be serious about this one thing. Because people with asthma in later stages of their life have many difficulties in breathing through the nose, and they do more gasping of air through the mouth. I will recommend you to buy one pulse oximeter which will help you analyze the SpO2 levels. Usually the normal range is in between 94-99. Also buy one respirometer - digital or spirometer to see the FEV1 readings. Most people with asthma have difficulties with doing forced expiration. In my clinical practice even at the age of 70+ responds well to individual designed pulmonary rehabilitation. In a recent case which I have seen is 75 years male with SpO2 levels around 70 and asthmatic. With the designed pulmonary rehabilitation plan of using the oxygen saturation machine and physical therapy for especially focused respiratory muscles has made avoiding the asthmatic attacks which are so bad that the person literally feels out of breath. Well the patient is doing much better and now the oxygen saturation levels are 97, so we are continued to follow and modify the pulmonary rehabilitation plan as and when needed.  Hope I have answered your query. Let me know if I can assist you further. Jay In Chat Doctor.
