Hello,I was recently turned away from a colonoscopy because my blood pressure was too high (170/110). I understand there is a proper way to take blood pressure readings and improper ways to take them.I am taking my blood pressure daily and logging it for my next doctors visit. What is the proper procedure for taking my blood pressure?Thank you,

Hi welcome to Chat Doctor Dear, You may need to take your BP at home if you have hypertension (high BP) or hypotension (low BP). High BP increases your risk for stroke, heart attack, or kidney disease. Low BP may cause you to feel dizzy or like you are going to pass out. This usually happens when you stand up quickly. You may need to take medicine to keep your BP at a normal level. Start the procedure with few dos and don'ts for accurate reading Do not check your blood pressure within 30 minutes of smoking, Chat Doctor.  These may affect your BP reading. Do not take a BP reading in an arm that is injured or has an IV or a shunt. Sit and rest for 5 minutes before you take your BP. Extend your arm and support it on a flat surface. Your arm should be at the same level as your heart. Both of your feet should be flat on the floor. The device has a built-in pump that inflates the cuff. Put the cuff about 1 inch (2.5 cm) above your elbow. Wrap the cuff snugly around your arm. The BP reading may not be correct if the cuff is too loose. Turn on the BP monitor and follow the directions. Write down your BP, the date, the time, and which arm you used to take the BP. If possible, take your blood pressure twice and write down both readings. These BP readings can be 1 minute apart. Let the air out of the cuff. Turn off the monitor and take off the BP cuff. Take your BP at least twice a day. Take your BP at the same times each day, such as the morning and evening for accurate reading.  Hope this helps solve your query. All the best.Don't hesitate to get back if you have any further query
