Introduction
If you’re a medical professional, then you may be familiar with the importance of drawing mixed venous from swan. Mixed venous blood is the blood that flows through the right atrium of the heart, and it’s often used to monitor the patient’s cardiac output and oxygen delivery. However, drawing mixed venous blood can be tricky, especially if you’re not familiar with the process. In this article, we’ll provide a comprehensive guide on how to draw mixed venous from swan in a relaxed English language.
Before You Begin
Before you begin the process of drawing mixed venous blood, it’s essential to ensure that the patient is appropriately prepared. The patient should be in a supine position, and the catheter should be appropriately placed in the pulmonary artery. You should also ensure that the equipment is ready, and you’re familiar with the process.
Step 1: Gather the Equipment
To draw mixed venous blood, you’ll need the following equipment:
- Syringe (10ml)
- Heparinized saline (10ml)
- Three-way stopcock
- Specimen tubes
- Alcohol swabs
- Gloves
Step 2: Prepare the Patient
Before you begin the process of drawing mixed venous blood, you should explain the procedure to the patient. You should also ensure that the patient is comfortable and relaxed. You should then clean the area around the catheter insertion site using an alcohol swab.
Step 3: Connect the Syringe to the Three-way Stopcock
Connect the syringe to the three-way stopcock and ensure that it’s tightly secured. You should then flush the syringe and the three-way stopcock with heparinized saline.
Step 4: Draw the Blood
Slowly pull the plunger of the syringe to withdraw the mixed venous blood. You should then remove the syringe from the three-way stopcock and attach the specimen tube. Ensure that the tube is tightly secured, and the blood is transferred into the tube.
Step 5: Label the Specimen Tube
Label the specimen tube with the patient’s name, date of birth, and other relevant information. You should then send the specimen tube to the laboratory for analysis.
