Conditions
Interventions
Observation group:The catheter tip position is determined as: the distance (cm) to withdraw outward after the P wave reaches its highest amplitude in the catheter placement position = 0~0.5 cm.
Control group:The final determination of the position of the catheter tip is as follows: Refer to the position of the catheter when it is in the supine position. After the peak of the P wave reaches i

Age
18 Years to No maximum
Inclusion criteria
Inclusion criteria: 1. Age >=18 years; 2. Patients who need to have a PICC catheter inserted for treatment; 3. Pre-insertion electrocardiogram shows identifiable P waves; 4. Patients who cannot tolerate the supine position due to reasons such as breathing difficulties; 5. Patients have given informed consent and voluntarily participated in this study.
Exclusion criteria
Exclusion criteria: 1. Patients with heart diseases such as valvular heart disease, atrial fibrillation, supraventricular tachycardia, pulmonary heart disease, or those who have received cardiac pacemaker implantation or undergone cardiac surgery, as these conditions may affect the changes in the P wave; 2. Patients with failed puncture due to various reasons; 3. Patients with mental abnormalities or those who are uncooperative. All patients signed the informed consent form for PICC catheterization.
