Case 2

Which factor in Fick's law caused the patient's oxygenation status to acutely worsen in this case?

Summary Introduction

To review:

The factor in Fick’s law that has caused the patient’s oxygenation status to acutely worsen in this case.

Introduction:

A 78–year-old woman is admitted to the hospital. She has a medical history of chronic interstitial lung disease, alveolar fibrosis, and thickening. Her X-ray reports were taken and they showed signs of higher alveolar density. When brought into the hospital, she was found agitated and anxious. Her respiration rate was noted as 24 breaths per minute and heart rate as 105 beats per minute.

Please refer to Clinical Application Case-2 for further information.

Explanation

Fick’s law is a law that equates the amount of gas diffused with various other factors involved. This law equates the thickness indirectly to the amount of diffusion. In this particular case, the woman is suffering a chronic lung disease accompanied with alveolar thickening.

The thickening of the alveolar membrane will result in decreasing the amount of gas (oxygen) diffused. So, for this case, the Fick’s law factor that worsens the condition of woman is thickness or T...
