Hi,

You are suffering from CO2 wash out seen if there is increased respiratory rate setting in the ventilatory machine and peep value low or high concentration of oxygen etc.

So decreasing the respiratory rate and increasing peep value is useful. Other possibilities like a sleep apnea, cardiac failure or paroxysmal nocturnal dyspnoea or nocturnal asthma may lead to dyspnea.

Please consult your treating physician, he will examine and treat you accordingly.

Hope I have answered your query. Let me know if I can assist you further.

Regards,
