Is ventilation needed for shortness of breath and hypoxia?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hello doctor,

I was admitted to the ER with shortness of breath due to cancer-related pneumonitis. I recently finished my first round of treatments a few weeks ago, but steroids have not been effective, and my condition is worsening, causing hypoxia.

The doctors are suggesting mechanical ventilation, but I have refused it as I believe it could cause more harm than good. Can the doctors override my decision based on my worsening hypoxia, even though I have repeatedly informed them that I do not want intubation?

Hello,

Welcome to icliniq.com.

I read your query and understood your concern.

I would like to inform you that shortness of breath can lead to depleted oxygen and increased carbon dioxide levels in the lungs, which a ventilator can help replenish. Prolonged hypoxia not only affects the lungs but can also have adverse effects on the brain and heart. The brain requires significant oxygen, so hypoxia can impact its functioning.

I suggest you consider going for ventilation if it is needed, as it can be beneficial rather than harmful. Once the parameters in the arterial blood gas (ABG) test normalize, the intubation tube can be removed. Have you done the ABG test? If yes, please share the reports with me, and I will review them to determine whether mechanical ventilation is necessary or not.

I hope this has helped you. Kindly follow up if you have more doubts.

Thank you.
