You should have your SaO2 tested to see how much capacity of 02 your lungs are taking. You can do it by having it tested on an oximeter. You put your finger in it and it shows how much oxygen your body is absorbing. The fact you are a smoker and have a history of lung problems is not a good prognosis for future outcomes. You should always have your flu shots before the flu season to be preventative with your health.
