I know exactly how you feel, I was in a very similar situation. I remember that I was so nervous at that time and I took it out on everyone around me. I didnt know what could I do until, thanks god, I found Smoke Deter. Now I can look back and laugh on myself and in the same time I remember how helpless I was. I hope that I'll never be in the same situation again
You deliver the oxygen that is needed to maintain a marginally acceptable PO2 … the theory of "Hypoxic Drive" is a faulty theory believed by many … but has no substantial basis to ….
In COPD patients, a low percentage of oxygen is a stimulus or a source of stimuli for the respiratory system to work, that’s why when we try to administer a high percentage of oxygen to this kind of patients, they’re drive to breath is decreased since oxygen level is already high.
COPD patients when receiving high flow oxygen can start retaining CO2.
However, you cannot deprive them of receiving the oxygen they need if they are in acute exacerbation. This can be very tricky…
You have to treat the immediate problem then worry about reversing the retention.
the COPD patient ’s nervous system uses oxygen as the stimulus to initiate respiration as opposed to the patient wihtout general sequalae whos system uses carbon dioxide in the cerebral spinal fluid as stimulus to initiate respiration…..alll this is partially controlled via chemoreceptors. in the COPD pt, it is believed that administering oxygen will cause the nervous system to sense the increased oxygen levels there by no longer providing a stimulus to breath………if you are an EMT forget about this stupid sh*t and give a patient who needs oxygen the oxygen.
