Patient's Query

Hello doctor,

I have been experiencing ongoing shortness of breath, initially considered anxiety or hyperventilation, persisting for a few days.

I am seeking assistance with arterial blood gas:

  1. pH: 7.546.

  2. PCO2: 30.4 mmHg.

  3. PO2: 101.9 mmHg.

  4. HCO3: 26.6 mEq/L.

  5. TCO2: 27.5 mmol/L.

Thank you.

Patient's Query

Hi doctor,

Thank you for your reply.

Have you reviewed my results? I just remembered that I have also lost my appetite. Please assist.

Thank you.

Hi,

Welcome back to icliniq.com.

I read your query and can understand your concern.

I apologize for the delayed response.

I have reviewed your lab reports (attachments removed to protect the patient's identity), and all the values are normal and within the limits. Your CBC (complete blood count), KFT (kidney function test), and glucose levels are normal.

Regarding the ABG (arterial blood gas):

  1. The pH is high, indicating alkalosis, a medical condition characterized by an elevated pH level in the blood.

  2. The low pCO2 (partial pressure of CO2) level suggests respiratory alkalosis, where decreased carbon dioxide levels in the blood are often caused by hyperventilation.

Possible causes of respiratory alkalosis include conditions that lead to hyperventilation, such as

  1. CNS (central nervous system) diseases like anxiety (excessive worry), fever, psychosis (altered state of mind), etc.

  2. Hypoxemia or tissue hypoxia is a condition with insufficient oxygen in the blood or inadequate oxygen delivery to body tissues.

  3. Drugs or hormones like Salicylates and Progesterone.

  4. Sepsis is a severe, life-threatening response to infection.

  5. Mechanical hyperventilation involves artificial or excessive breathing, potentially affecting the body's acid-base balance.

I understand this may be confusing, and I would like to provide more detailed guidance based on your medical symptoms. Please share your current symptoms and the reason for getting these lab tests done.

I hope this helps.

Please revert so I can assist you further.

Thank you.
