3. If you are taking antihypertensive medications, continue to take them as scheduled on the day of the examination.

1. Complete and sign the examination consent form.
2. Complete the required blood tests.
3. Inform your doctor if you are taking anticoagulants. These medications prolong blood-clotting time and reduce blood clot formation.
4. Do not eat or drink anything for at least 4 hours before the examination. If you are taking antihypertensive medications, take them at the scheduled time with 20–30 mL of water.
5. If bronchoscopy is performed under sedation or general anesthesia, an anesthesia consultation and consent form are required beforehand.

1. In the examination room, the doctor will spray a local anesthetic into your throat or nose. If you feel uncomfortable during the examination, raise your hand to inform the healthcare staff for assistance.
2. If you receive sedation, the anesthetic will be given through an intravenous line.
3. The examination takes about 30 minutes. You will need to lie flat with your head tilted backward.
4. When the bronchoscope reaches your throat, follow the doctor's instructions and swallow when asked.

1. The doctor will determine whether a chest X-ray is needed 4 hours after the examination.
2. Rest for 1–2 hours after the examination. Start with a small sip of water. If you do not experience choking or nausea, you may begin eating. Choose soft foods, such as porridge or steamed eggs, and gradually return to your normal diet.
3. Please arrange for a family member to accompany you home on the day of the examination.
4. You may have a sore throat, cough, sputum, or a small amount of blood-streaked sputum for 1–2 days after the examination. Seek immediate medical attention or go to the emergency department if you develop a fever, difficulty breathing, chest pain, or cough up several spoonfuls of blood.
