Question

Common causes of sluggish, delayed, or prolonged capillary refill (>2 secs) are

Answer 1

The common causes of sluggish, delayed, or prolonged capillary refill of more than 2 seconds are low partial pressure of oxygen, abnormal neural signals, and small venous reserve of oxygen.

Step-by-step explanation:

When the capillary refill takes longer than 2 seconds, it can indicate sluggish or delayed blood flow. There are several common causes for this:

1. Low partial pressure of oxygen: If there is a decrease in the oxygen content in the blood, it can lead to delayed capillary refill.
2. Abnormal neural signals: Certain conditions can affect the signals from the nervous system that control blood flow, resulting in sluggish capillary refill.
3. Small venous reserve of oxygen: If the blood returning to the heart has a low oxygen content, it can cause delayed capillary refill.
