Physical examination overview

Physical examination is a basic medical method for doctors to evaluate the patient's physical condition through visual, touch, percussion, listening and other methods. It mainly includesGeneral examination, head and neck examination, chest examination, abdominal examination, spine and limb examination, nervous system examinationand other core content. Among them, vital signs (body temperature, pulse, respiration, blood pressure) and systemic status (nutrition, development, consciousness) are priority items, followed by in-depth inspection by system partition. Inspection tools such as stethoscopes, sphygmomanometers, etc. are necessary auxiliary equipment and must be operated in a standardized manner to ensure accurate data.

General examination and vital signs

The first step in the physical examination isGeneral inspection, including observing the patient's face, body position, skin color and measuring vital signs. For example, blood pressure measurement requires the use of a certified sphygmomanometer (such as Yuyue Medical's YE680 series), and a commonly used electronic thermometer (such as Omron MC-246) is used for body temperature detection. At this stage, it is also necessary to record height and weight, calculate BMI index, and initially judge nutritional status or potential metabolic diseases.

System Partition Check Points

After completing the basic assessment, the doctor will pressHead and neck, chest, abdomenIn-depth inspection of other partitions. The thyroid gland and lymph nodes need to be palpated in the head and neck; the cardiopulmonary function is judged by percussion and auscultation of the chest; the focus of abdominal examination is palpation of the liver and spleen and auscultation of bowel sounds. For example, stethoscope brands such as 3M Littmann are often used to collect heart and lung sounds, and percussion techniques need to follow international standards to avoid misdiagnosis.

Spine, limbs and nervous system

The spine examination focuses on curvature and tenderness, and the limbs need to assess joint mobility and edema; the neurological examination includes reflex testing (knee jerk reflex), muscle strength, and sensory assessment. Some special examinations such as Babinski sign require the assistance of professional tools. Commonly used equipment in the rehabilitation department, such as Hausmann Medical's muscle strength tester, can quantify data.

Summary and clinical significance

Physical examination is the cornerstone of disease screening and health assessment, and its standardized process can effectively identify abnormal signs. For example, abnormal blood pressure may indicate hypertension, while swollen lymph nodes may warrant further investigation for infection or cancer. In modern medical treatment, the combination of traditional techniques and digital equipment (such as United Imaging Medical's intelligent imaging system) has improved examination efficiency and accuracy.
