  Author:MeCan Medical–ultrasound machine manufacturers

Blood gas analysis is a check method for evaluating the respiratory function and the pH of the body's respiratory function and the acid -base of the body. Blood gas analysis can not only intuitively reflect the patient's lung replacement function, but also has very important reference significance for understanding the acid and alkali balance of the body.

At present, the blood source of blood gas analysis is mainly two types: arterial blood and venous blood. Blood gas analysis is an important indicator of rescue of critical patients and monitoring during the operation. It has a wide range of clinical application. It is an indispensable means of examination of patients with severe patients. So what problems should be paid attention to when performing blood gas analysis?

1. Pay attention to sterile operations and prevent infection. The disinfection area is 8-10cm.

2. Press the puncture site for 5-10min until no bleeding.

3. Patients with bleeding tendencies should be used with caution (not using deep arteries puncture, prolonged or compressed bandaging).

4. If the patient drinks hot water, bath, exercise, and rest for 30 minutes before taking blood.

5. Partial part must be infected without infection and strict disinfection.

6. Avoid repeated punctures to avoid forming hematoma or local congestion (such as hematoma and pain in time to give cold compresses in time).

7. Take arterial blood to prevent air from entering.

8. After the specimen is collected, the inspection should be sent immediately (when the nurse is busy is not delivered) to the cold box of 4 C, but it should not exceed 2 hours, so as to avoid cell metabolic oxygen consumption, reduce PAO2 and pH, PACO2 increases Essence

9. Fill in blood gas analysis application forms to indicate blood collection time, body temperature, patient oxygen absorbing method, oxygen concentration, oxygen flow, mechanical breathing various parameters, etc.

In addition, in daily work, the daily maintenance and maintenance of the blood gas analyzer should be strengthened to avoid related conditions such as the failure and large errors of test indicators. At present, arterial blood gas analysis has become an indispensable testing item for the diagnosis and treatment of hypoxemia and acid -base imbalance in the clinical department, which has very important clinical significance for the treatment of patients with critical condition.

Why Do Patients with Slow Pulmonary Blockers Need Non -invasive Ventilator? What Is the Application
  Author:MeCan Medical–ultrasound machine manufacturersNow the continuous increase in patients with slow pulmonary blocking, how should this situation be relieved? In the early days of slow obstruction, non -invasive ventilator was required to treat patients with a slow obstructive pulmonary. Due to damage to respiratory function, carbon dioxide retention in the body would form carbon dioxide. This will cause carbon dioxide to increase the division of carbon dioxide, and the acid -base balance in the body is unbalanced, which reduces the resistance of patients with chronic pulmonary patients, prone to colds, and causes acute aggravation of the condition.Due to the initial stage of slow obstruction, the patient will have carbon dioxide retention and feels difficulty in breathing. Therefore, it is necessary to use non -invasive ventilator to improve symptoms and relax fatigue muscle. The use of ventilator as soon as possible can not only improve the quality of life of patients with chronic pulmonary blockers, but also help reduce the number of acute seizures and reduce the number of hospitalizations per year. Which household ventilator is suitable for patients with chronic lung block?There are two main types of household non -invasive ventilator, each with different characteristics of the disease. One is the non -invasive ventilator for sleep problems, mainly to deal with diseases such as sleep apnea; the other is non -invasive ventilator for respiratory diseases, including breathing function, slow lung blocking, etc. Select ventilator dedicated to respiratory diseases. Among them, dual -level non -invasive ventilator with ST mode is the primary choice for slow pulmonary treatment to ensure the effectiveness and safety of home treatment.The ST mode can not only provide inhalation pressure and exhalation pressure, but also set a reserve breathing frequency. The role of this setting is that if the patient's autonomous breathing ability is strong, the ventilator can provide breathing support according to its respiratory frequency to assist the breathing of patients with slow pulmonary patients; For standards, the ventilator will automatically turn on the reserve breathing frequency. The patient is forced to breathe through the active air delivery method. To a certain extent, the patient's breathing is maintained to avoid danger.As a manufacturer of non -invasive ventilator, Progen Medical Equipment currently has a lot of non -invasive ventilator and available to choose from.

The necessary monitoring equipment, such as X -ray machines, blood gas analysis, pressure meter, oxygen metering meter, etc. Whether the vessels threaded Whether there is a leak loss, whether the patient has sputum, and related treatment according to different situations.2. Regular disinfectionFor patients with bronchiers, the cutting place should be replaced daily. Oral care should be covered twice a day, and the mouth and nose are covered with a wet gauze. The airbags and tracheal tube airbags are relieved every 4 hours, and each time it is relieved for 5-10 minutes. Medical creation ventilator joints disinfected once a day. The ward is illuminated by 1%to 2%peroxide or ultraviolet lights every day. The external pipeline and atomizer device of the ventilator are replaced every 2 to 3 days.3. Strengthen wetness and atomizationPatients with a ventilator must strengthen the dampness of the respiratory tract. It is commonly used in the trachea to continue to slowly sterilize injection of water with a micro-amount pump with a micro-pump with a 1-2ml/h pump. Daily atomized 2 to 3 times. If there is a sputum or sputum coughing after the atomization, it should be taken in time.4. Clear sputum in timeFor patients who use mechanical ventilation, pay attention to whether there is a sputum stasis at any time, and closely observe the oxygen saturation when absorbing sputum. Be less than 87%of the ventilator joints, and the oxygen saturation rises to more than 97%. Pump. Put the sputum is replaced daily. During the sputum absorption process, we should strictly operate and wear sterile gloves to prevent lung infection.Check the equipment carefully before using a ventilator: the connection of each pipeline, whether the airway pressure is within the scope of the scheduled, whether the individual parameters are set, whether the water in the wet tank meets the requirements, and whether the various alarm values are set appropriate.

Why Do You Need to Detect These Specific Proteins and CRP Detection?
Why Do You Need to Detect These Specific Proteins and CRP Detection?
  Author:MeCan Medical–ultrasound machine manufacturersSpecific protein refers to functional proteins in blood, urine, cerebrospinal fluid, thorax, pericardium, and pericardium. The laboratory uses antigen-antibody reactions to determine the protein with a specific antigenicity in the body fluid, which is called specific protein detection. So why do you need to detect these specific proteins?The changes in protein are closely related to the physiological and pathological changes of many diseases, including infectious diseases. Infectious diseases refer to a major type of diseases caused by the human body infected with various pathogens (such as viruses, bacteria, fungi, and parasites). After the pathogen and the human body interaction, a series of specific proteins can be produced. These proteins can be produced by bacteria active or bacterial infection. These proteins can be used for assisting diagnosis, severity assessment, and prognosis judgment of infectious diseases.For example, a C-reactive protein (CRP) of specific protein detection. When bacterial infection, CRP increased significantly, and the body was infected rapidly after 6-8 hours. Normally, patients with acute phase infection increase the severity of the disease.CRP can identify bacterial or viral infections and know whether to use antibiotics; CRP is particularly prompting for patients who cannot express symptoms (such as infants, coma, and dementia patients, etc.); provide a basis for the diagnosis of newborn bacterial infections; Improve the accuracy of risk prediction of cardiovascular disease, and dynamically monitor the course of the disease. It is used in various acute inflammation, tissue injury, myocardial infarction, surgical trauma infection, and malignant tumor infection.In addition, specific protein analyzers can also be detected: kidney skills series: cuscotin C (CYS-C), 2-macaroprotein, neutrophils of messengase-related carrier protein (Ngal) Combining protein (RBP), urine microfilled white protein (MA), rotor protein (TRF); inflammation series: C-reactive protein (CRP), ultravisive C-reactive protein (HSCRP); rheumatoid series: rheumatoid factor (rheumatoid factor ( RF), Antibacteria oligoen (ASO), etc., provides important basis for the diagnosis of the condition.
