Measuring a Mid-Upper Arm Circumference

Summary

The video script provides instructions on measuring mid-upper arm circumference, a useful method for monitoring weight changes when weighing isn't possible. It emphasizes the importance of repeating measurements over time and consulting with a dietitian for interpretation. The process involves finding the midpoint between the shoulder and elbow, using a disposable measuring tape, and ensuring the tape is neither too tight nor too loose. The final measurement is recorded and shared with a dietitian for further guidance.

Takeaways

• 📏 Middle Arm Circumference (MAC) is a useful measurement when weighing is not feasible.
• 🔍 MAC doesn't indicate a specific weight but can show weight changes over time.
• 👩‍⚕️ A dietitian can advise on the frequency of MAC checks and interpret the measurements.
• 👥 Assistance from another person may be needed for children or individuals with difficulty following instructions.
• 🧳 Essential equipment includes a non-disposable measuring tape and a ballpoint pen.
• 🧼 Hand hygiene is important; wash hands for at least 20 seconds before the measurement.
• 🧤 In clinical settings, gloves or personal protective equipment (PPE) may be necessary.
• 🤲 The measurement should be taken on the left or least affected arm, especially for those with conditions like stroke.
• 📐 Locate the midpoint of the arm by measuring from the shoulder bone to the elbow and marking the halfway point.
• 📋 Ensure the arm is relaxed and hanging naturally when taking the circumference measurement.
• ✏️ Record the measurement accurately, ensuring the tape is neither too tight nor too loose.

Q & A

What is the purpose of measuring mid-upper arm circumference?

Measuring mid-upper arm circumference can be helpful if it is not possible to weigh a person, as it does not indicate a specific weight but can show if someone is gaining or losing weight over time.

Who should advise on how often to check a person's mid-upper arm circumference?

A dietitian should advise on how often to check a person's mid-upper arm circumference.

Why might two people be needed to take a mid-upper arm circumference measurement?

Two people may be needed to take a mid-upper arm circumference measurement on a child or a person who may struggle to follow instructions.

What equipment is required to measure mid-upper arm circumference?

A non-disposable measuring tape that the dietician can provide and a ballpoint pen are required.

Why is handwashing important before taking the measurement?

Handwashing for at least 20 seconds is important for hygiene purposes before taking the measurement, and in a clinical setting, wearing gloves or relevant PPE may also be necessary.

Which arm should be measured for mid-upper arm circumference?

The measurement should be taken on the left or least affected arm if the person has had a stroke or has altered tone in their limbs.

How should the arm be positioned to find the midpoint for measurement?

The arm should be bent at a right angle to locate the midpoint, which is found halfway between the tip of the shoulder bone and the tip of the elbow.

What is the correct position of the arm when taking the circumference measurement?

The arm should be hanging down by the side of the body and relaxed when taking the circumference measurement.

How should the tape measure be positioned and used during the measurement?

The tape measure should be placed around the midpoint of the arm without pinching the skin too tight or being too loose, and the zero mark should line up with the measurement.

What should be done with the measurement after it is taken?

The measurement should be recorded and sent to the dietitian, who will interpret the results and advise on any necessary changes.

Why is it important not to focus on the colors on the tape measure?

It is important not to focus on the colors on the tape measure because the dietitian will interpret the numerical measurement, and the colors are not relevant for this purpose.
