For critical patients who carry out invasive intravascular monitoring, all blood samples should be taken from arteries, patients who cannot obtain arterial blood should be kept and venous blood samples should be taken, and capillary blood sample (acupuncture) measurement results are inaccurate and are avoided. Capillary blood sampling (needle punching) is used for patients with relatively light disease and without invasive intravascular monitoring. When the patient in the ICU intensive care unit is seriously ill, an arterial blood pressure monitoring device is arranged, and more than a radial artery catheter is arranged. Therefore, the blood gas can be monitored by utilizing the invasive device of the radial artery catheterization, and the additional increase of an invasive implantation passage of a patient can be avoided.
