Why do the pulse rate and CO2 levels spike after a heart attack?

Question

Hi doctor,

A few days ago, he experienced a heart attack and was subsequently admitted to the hospital. While initially showing signs of improvement, this morning, his pulse rate spiked to 160 bpm, and there is an increase in CO2 levels. Since then, he has been unconscious and is currently on a ventilator. His medical history reveals a chronic breathing issue due to cough deposition, and he is presently on medication to manage high blood pressure and ensure proper blood circulation. The situation appears critical, and prompt medical attention is strongly recommended. Kindly help.

Thank you.

Answer 1

Hello,

Welcome to icliniq.com.

Thank you for your query.

Raised CO2 and Low O2 in blood is type 2 respiratory failure. Ventilatory support is provided till the acute issue resolves, like respiratory tract infection, exacerbation of COPD (chronic obstructive pulmonary disease), or heart failure. Please share his ECG (electrocardiogram) so that I can guide you about it.

I hope my advice will be helpful. Feel free to reach out if you have any further queries.

Thank you.

Answer 2

Hi,

Welcome back to icliniq.com.

He is on 90% FiO2 and maintaining saturation on it. Once the condition improves, it will be decreased gradually. Heart rate is fast, and sinus tachycardia is most likely secondary to acute metabolic stress, medication effects, severe infection, etc. He is maintaining blood pressure. I do not know whether his BP is on support or without support.

Heart rate is not an issue at this time. Issues are other derangements that have led to fast heart rates. The condition and prognosis depend upon the condition of the lungs, kidneys, heart, and brain. All vital organs are important.

I hope my advice will be helpful. Feel free to reach out if you have any further queries.

Thank you.
