What does E2 mean on blood pressure
E2 is an abbreviation used to refer to diastolic pressure, which is the bottom number of the blood pressure reading. Diastolic pressure measures the pressure in the arteries when the heart is at rest between beats. It is the lower number in a blood pressure reading and is typically given first when measuring blood pressure.
Diastolic pressure is important as it is an indicator of cardiovascular health. A normal diastolic pressure is typically around 80 mmHg (millimeters of mercury). A higher-than-normal diastolic pressure may indicate that there are underlying issues with the heart or circulatory system that need to be addressed. On the other hand, a lower-than-normal diastolic pressure can also indicate issues, such as dehydration or low blood volume.
Having an understanding of E2 and its importance can help individuals monitor their own blood pressure readings and take appropriate steps to maintain good cardiovascular health. It is important to have regular checkups with a doctor to ensure that your blood pressure remains in a healthy range. If your diastolic pressure falls outside of a normal range, it may be time to seek medical attention.

What does 2 blinks mean on my furnace
If your furnace has two blinking lights, it usually means that your furnace is having an issue with its flame sensor. When a furnace is operating properly, the flame sensor detects that there is a flame present in the burners, and then sends a signal to the furnace control board to keep running. If the flame sensor does not detect a flame, it will send a signal to the control board to shut off the burners and flash two indicator lights.
The most common causes of two blinking lights on a furnace are due to a dirty flame sensor or a faulty flame sensor. The flame sensor is located inside the furnace and is used to detect whether or not the burner is lit. If the flame sensor has become dirty or corroded, it will not be able to accurately detect the presence of a flame and will send an incorrect signal to the control board. This will cause the furnace to shut down and flash two lights.
In order to fix this problem, you must first locate and clean the flame sensor. To do this, turn off the power to your furnace and locate the flame sensor inside your furnace. Once you have found it, use a wire brush to clean off any dirt or debris that might be on its surface. After cleaning, turn on the power again and check if your furnace is still flashing two lights. If it is still flashing two lights, you may need to replace your flame sensor with a new one.
If cleaning or replacing your flame sensor does not solve the issue, you should contact a professional HVAC technician for assistance. They can further diagnose and repair any other underlying issues that may be causing your furnace to malfunction.
