What should I do if there is air during the infusion?

When the infusion is found, there is air in the infusion tube, you must immediately suspend the infusion tube as soon as possible, and then pull out the needle to discharge the air, so that it is okay, otherwise the air entering the blood will easily induce death.

To expel the bubbles while they have not yet been infused into the body, unscrew the knob on the infusion tube, and then discharge the bubbles until the bubbles are discharged.

Sometimes there will be bubbles in the infusion tube, under normal circumstances, the medical staff are with a few flicks of their fingers, the bubbles will follow the infusion tube back to the infusion, if it is a bubble, and the medical staff did not find it, we must close the flow control valve in time, and then call the medical staff to deal with it, because the air injection into the blood is life-threatening.

Divided into four positions:

1. Position 1.

On the top of the Murphy dropper, ignore it completely, the liquid will come down on its own.

2. Position 2.

Here it is mainly the Murphy dropper liquid handling.

High liquid level: You can fold the bottom of the Morphe dropper back, remove the liquid bottle, and squeeze the excess liquid from the Morphe dropper back into the liquid bottle.

Low liquid level: You can fold the bottom of the Morphe Dropper and squeeze the Morphe Dropper to let the liquid above enter the Morphe Dropper.

Three, position three.

Small amount of gas: Close the adjustment clip, pull the infusion tube straight from top to bottom, and pop the bubbles up from bottom to top.

Large quantities of gas: There are three main ways.

1. Close the regulator and roll the infusion tube on your fingers from bottom to top, and the air will go up.

2. Close the regulator and roll the infusion tube on the pen from bottom to top, and the air will go up.

3. Close the regulator and push the adjustment clamp directly from bottom to top, and the air will go up.

Fourth, position four.

A large amount of gas: It is better to discharge, but it is important to note that special drugs cannot be wasted casually.

A small amount of air bubbles: It doesn't matter, nowadays ordinary infusion sets have a filtered connector that can handle a small amount of air bubbles.

While one or two bubbles will not be a problem to get in, it is important to avoid them.

Hello, Generally speaking, a small amount of air entering the blood vessel will not cause the patient's symptoms, when there are several reasons, accidentally a small amount of gas enters the vein, the patient has different degrees of symptoms, such as dyspnea, cough, chest tightness, wheezing and cyanosis, etc. In severe cases, coma and death can occur. Thank you for adopting

The air will go like this: veins - right atrium - right ventricle - pulmonary artery - lungs, when the amount of air is large, it will block the pulmonary artery orifice, so that blood can not enter the lungs, gas exchange disorders occur, and the body is ischemia and hypoxia.

If the amount of air input is small, such as a small bubble, you don't have to worry about it, just observe the situation.

If the amount of air input is large, such as 10 ml, it can be left side decubitus position or head down and foot high position, which is conducive to air drift to the right ventricle apex, with the heart contraction, larger bubbles are dispersed into small bubbles, divided into small amounts into pulmonary arteries, and gradually absorbed.

As for how much air is injected, embolism is not easy to determine, because clinical and theoretical are always a little different, and there are many clinical factors, such as the infusion person's own lung disease. Therefore, the infusion patient should be closely observed during the infusion, whether there is dyspnea, chest tightness, cyanosis, chest discomfort, retrosternal pain, etc. Symptomatic treatment should be prompted.

Oxygen inhalation, etc.

One reason is that the liquid column is separated by strong vibration during transportation or use, and there is a gap in the middle.

In addition, it may be exposed to high temperatures, and the liquid column will squeeze to the top, and the middle part may be disconnected due to horizontal placement during cooling.

This blank segment refers to the fact that the land is not mixed with air in the middle, but simply separated by liquid columns, and the blank space is the vapor of alcohol.

2 workarounds:

Shake it vigorously and press the liquid column to the bottom with centrifugal force to squeeze out the blank section. This should pay attention to the technique, sometimes shake it off and then separate and touch. If there is a centrifugal sedimentation machine of the appropriate size, just put it on it for a turn.

Another way is to subjecte it to the right temperature, so that the liquid column fills the tube to the top, and then it is placed upright to cool naturally, which will eliminate the blank.
