Uses Of Medical Anesthesia Machine

What is an anesthesia machine?

The anesthesia machine delivers the anesthetic into the patient's alveolus through a mechanical circuit, forming a partial pressure of the anesthetic gas. After it diffuses into the blood, it directly inhibits the central nervous system, thereby producing the effect of general anesthesia. The anesthesia machine is a semi-open anesthesia device. It is an advanced medical equipment that can transport a variety of gases and volatile anesthetics, control and assist the patient's breathing, and at the same time adjust the patient's consciousness and pain level during the operation.

Function

The anesthesia machine is one of the necessary equipment in the operating room in modern medicine. It can provide stable breathing and circulation conditions for the operation and ensure the smooth progress of the operation. At the same time, anesthesia machines are also used in intensive care and emergency resuscitation, playing an important role in saving patients' lives.

Classification

According to different purposes and functions, anesthesia machines can be divided into different types such as portable, desktop and vertical. In addition, anesthesia machines can be divided into integrated and separate types depending on whether they are equipped with a ventilator.

Composition

The anesthesia machine mainly consists of anesthesia machine shell, anesthesia ventilator, vaporizer, various gas alarm devices and oxygen. Among them, the anesthesia ventilator is one of the important components of the anesthesia machine. It can provide stable breathing conditions and ensure the safety of the patient. Vaporizers are used to store anesthetic drugs for the convenience of doctors. Various gas alarm devices are used to monitor the concentration of oxygen, nitrogen and other gases to ensure the safety of surgery. Oxygen is used to provide the oxygen needed for breathing.

History and development

The development of anesthesia machines began in the late 19th century. At that time, people began to use ether and other anesthetic drugs for surgery. With the continuous advancement of science and technology, anesthesia machines have gradually developed into complex medical equipment that can provide more stable and safe breathing and circulation conditions.

With the continuous development and advancement of medical technology, anesthesia machines are constantly being improved and perfected. Modern anesthesia machines have become intelligent, digital and multifunctional, and can meet the needs of various surgeries. At the same time, anesthesia machines are constantly improving safety, reducing the incidence of complications, and providing more reliable protection for patients' life safety.

How an anesthesia machine works?

1.Invasion and Intubation

Before the procedure begins, the doctor will put the patient to sleep with appropriate sedation and place an endotracheal tube into the patient's airway. The purpose of endotracheal intubation is to ensure that the anesthetic gas can enter the patient's lungs smoothly and exhaust the waste gas.

2.Ventilation and breathing

The anesthesia machine provides an appropriate mixture of anesthetic gas and pure oxygen, which is delivered to the patient's lungs through an endotracheal tube. The patient's lungs absorb the anesthetic gas and deliver oxygen to the blood. At the same time, the anesthesia machine monitors the patient's respiratory rate and depth to ensure that the patient's breathing is normal.

3.Anesthesia control

The control system will monitor the parameters of the anesthesia machine in real time, such as the concentration of anesthetic gas and the patient's respiratory rate. Based on these monitoring results, the control system will automatically adjust the output of the anesthesia machine to ensure the stability and safety of the anesthesia effect.

4.Monitor and adjust

The monitoring system will monitor the patient's physiological status and important life indicators in real time, such as blood oxygen saturation, heart rate, blood pressure, etc. Doctors and anesthesiologists can promptly adjust the parameters and operations of the anesthesia machine based on these monitoring results to maintain the patient's stable state during the operation.

Preparation before anesthesia

1.Pre-anesthesia assessment

Conduct a comprehensive assessment of the patient's physiological status and anesthesia risks to determine a suitable anesthesia plan.

2.Preparation before anesthesia

Prepare necessary equipment and drugs such as anesthesia machine, anesthetic drugs, breathing tubes, and oxygen.

3.Patient preparation

Explain the anesthesia process to the patient, eliminate the patient's nervousness, and require the patient to make necessary preparations such as fasting and water deprivation.

Operations during anesthesia

1.Induction of anesthesia

Anesthetic drugs are given to make the patient lose consciousness and enter an anesthetic state.

2.Endotracheal intubation

Insert the breathing tube into the patient's trachea to ensure that the patient can breathe smoothly.

3.Anesthesia maintenance

Adjust the use of anesthetic drugs according to surgical needs to maintain the patient's anesthesia state.

4.Intraoperative monitoring

Monitor patients' vital signs including heart rate, blood pressure, respiration and other indicators to detect and deal with abnormalities in a timely manner.

Post-anesthesia treatment

1.Anesthesia recovery

Stop using anesthetic drugs and allow the patient to gradually wake up.

2.Extubation

When the patient is fully awake, remove the breathing tube from the patient's trachea.

3.Postoperative pain treatment

Give appropriate analgesics to relieve the patient's postoperative pain.

4.Discharge guidance

Provide patients with post-discharge precautions and follow-up recommendations.

Routine maintenance of anesthesia machine

1.Cleaning and Disinfection

Clean the surface of the machine promptly after daily use and disinfect the machine regularly to prevent bacterial growth and cross-infection.

2.Instrument inspection

Check whether the various instruments of the machine are working properly, including oxygen and carbon dioxide flow meters, blood pressure and respiration monitors, etc.

3.Pipeline maintenance

Regularly check the machine's piping system, including oxygen inhalation tubes, exhalation tubes, and suction tubes, to ensure they are unobstructed.

Regular maintenance of anesthesia machine

1.Lubrication and maintenance

Lubricate the moving parts of your machine regularly to reduce wear and friction.

2.Electrical inspection

Check whether the machine's electrical components are working properly, including power supplies, cables, sensors, etc.

3.Air system inspection

Check the machine's gas system, including oxygen bottles, air bottles and carbon dioxide absorption tanks, to ensure they are working properly.

Precautions when using anesthesia machine

1.Strictly abide by operating procedures

When using an anesthesia machine, operating procedures should be strictly followed to avoid illegal operations and incorrect operations.

2.Confirm patient status

Before using the anesthesia machine, the patient's status, including age, weight, vital signs, etc., should be confirmed in order to choose the appropriate anesthesia plan and drugs.

3.Pay attention to the patient's breathing

When using the anesthesia machine, attention should be paid to the patient's breathing conditions to ensure smooth breathing and avoid respiratory obstruction and suffocation.

Operating safety regulations for anesthesia machine

1.Check before operation

Before operating the anesthesia machine, a comprehensive inspection should be carried out, including whether the equipment connection, power supply, air source, etc. are normal, as well as various safety precautions.

Whether the protective equipment is complete.

2.Pay attention during operation

When operating the anesthesia machine, attention should be paid to observing the patient's vital signs and anesthesia status, as well as the operation of the equipment. If any abnormality is found,operations should be stopped immediately and appropriate measures should be taken.

3.Cleaning up after operation

After the operation is completed, cleanup work should be carried out, including cleaning equipment, turning off power and sources, etc., as well as recording and archiving work.
