Introduction

Introduction If the lips are purple, it can be confirmed that the lips are purple due to hypoxemia. The oxygen saturation in the blood (can be understood as the amount of oxygen carried in the unit blood, the amount of oxygen carrying more saturation), the higher the color of the blood (bright red), and vice versa, the blood is red or even black. When the human blood oxygen saturation is low, the color of the blood is purple, so the lips will look purple.

Cause

Cause

One of the reasons why the lips are purple (bun): low oxygen in the blood

If the lips are purple, it can be confirmed that the lips are purple due to hypoxemia. The oxygen saturation in the blood (can be understood as the amount of oxygen carried in the unit blood, the amount of oxygen carrying more saturation), the higher the color of the blood (bright red), and vice versa, the blood is red or even black. When the human blood oxygen saturation is low, the color of the blood is purple, so the lips will look purple.

The lips are purple (hair), the second reason: cold

In the spring and winter, observe the color of the lips immediately after coming out of the bed. Then, after washing the cold water, you will find that the color of the lips after washing will be purple before washing. In winter or swimming, many people will have purple lips. This is because in order to maintain the body temperature in the body, the body will first allow the peripheral blood vessels to contract, and the blood flow will also be reduced to prevent the loss of heat. Slower blood flow slows down the oxygen saturation in the peripheral blood vessels, so the color of the blood turns purple, so the lips will be purple.

Dynamic electrocardiogram (Holter monitoring) ECG

1. Hairpin with dyspnea: common in severe heart, lung disease and acute respiratory obstruction, a large number of pneumothorax, etc., although methemoglobinemia has obvious cyanosis, but generally no breathing difficulties.

2. Hairpin with clubbing (toe): suggesting a longer course. Mainly found in hairy congenital heart disease and some chronic lung diseases.

3. Hairpin with disturbance of consciousness and failure: mainly seen in certain drugs or chemical poisoning, shock, acute lung infection or acute heart failure.

Diagnosis

Differential diagnosis

The cyanosis caused by the disease needs to be identified in time with the toxic hair loss. Generally, when the toxic hair loss occurs, it will be accompanied by vomiting, abdominal pain, dizziness, palpitations and other symptoms. When toxic caries occur, urgent measures need to be taken.
