How To Choose The Best Pulse Oximeter For Your Doctor’s Bag

Pulse oximetry is a simple, noninvasive and reliable method for rapidly assessing arterial oxygen saturation (SaO2/SpO2) and pulse rate in patients. It is a useful tool for assessing both adults and children.

The main indications of pulse oximetry include the assessment of acute respiratory infections, asthma, COPD and heart failure. In these situations it can provide valuable information about the severity of the illness and help when deciding on the need for hospital referral or admission.

What Are The Guidelines?

In the General Practice setting, the importance of measuring oxygen saturations has been emphasised in the NICE guidelines on COPD, the SIGN guidelines on asthma and community acquired pneumonia and the NICE sepsis guidelines. Assessing oxygen saturation should be used alongside clinical assessment, not as a standalone indicator.

Additionally, pulse oximetry helps to ensure that hypoxic patients are treated appropriately with oxygen. The NICE sepsis guidelines highlight the importance of assessing oxygen saturations when risk stratifying patients.

How Much Do They Cost?

All-in-one pulse oximeters can vary greatly in price from under £10 to over £200.

How Do I Choose A Pulse Oximeter?

There is so much choice available that it can be difficult to know where to begin. When selecting a pulse oximeter for your doctor’s’ bag, ensure that it is:

  • Lightweight & Portable – Keeping your doctor’s bag as light as possible will make your life much easier when you’re on the move.
  • Simple-To-Use – With just 10 minutes per consultation, the quicker you can perform an examination, the sooner you can help the patient. A simple-to-use pulse oximeter opens like a crocodile clip and should be able to be used on a wide variety of patients.
  • Cost-Effective – Nowadays, you don’t need a top-of-the-range model to see great results. A £30 model will serve as well, if not better than a £100+ model as they are often more lightweight and aren’t as expensive to replace if they become damaged or go missing.
  • Reliable & Accurate – It should go without saying that when assessing a patient, accurate and reliable results are essential. Look for models with signal strength indicators as one of the main causes of inaccuracy in oximetry is incorrect finger insertion.

Additional useful features include being easy to clean (by wiping with a 70% IPA swab, for example) and battery-saving features such as automatically turning off when a finger is withdrawn.

A Note On Assessing Children

When assessing children make sure you invest in a paediatric pulse oximeter as obtaining a correct fit is important to give an accurate reading. In the past, many GPs had to resort to using an adult pulse oximeter to try to assess a sick child. The readings that resulted were often incorrect, if they could be obtained at all.

As you can see above, the adult pulse oximeter (right) is too large to be used effectively on paediatric patients. The two paediatric pulse oximeters fit much more closely, keeping the sensor in contact with the skin and giving more reliable results.

At Medisave, there is a wide range of high-quality, adult and paediatric pulse oximeters from tried and trusted brands including Nonin, ChoiceMMed, Daray and many more.

How to Use Social Media for Medical Research

Over the last few years, medical professionals have been learning how to use social media as a research tool.

For some, using Facebook or Twitter in the serious context of healthcare studies seems a little odd. After all, aren’t these networks full of people sharing photos of their dinner or silly videos of their cat?

The reason why people share banal photos online is the same reason why social networks can make outstanding research tools. It’s because Facebook, Twitter, Instagram and the rest make it really easy to communicate with a large, diverse audience.

For this reason, anyone involved in medical research, should give serious consideration to incorporating social media into their methodology.

There’s More to Hand Hygiene Than Hand Washing

The simple washroom sign ‘Now wash your hands’ is literally a lifesaver. Millions of infections would be avoided if people took a moment to clean their hands correctly. Worryingly, the biggest source of this problem is in healthcare settings, such as hospitals.

A visit to hospital, a medical clinic or a dental surgery may not only bring healing, but also exposure to microorganisms that cause infection. Whenever there is physical contact between a patient and a member of the medical team, or a piece of equipment, there’s a risk of contamination. But the one action that would cut these dramatically is, according to the WHO, the correct and timely washing of hands.

On 5 May 2016 the World Health Organisation (WHO) ran its annual event to highlight the importance of hand hygiene with its SAVE LIVES: Clean Your Hands campaign. This year the message focused on infection prevention and control in healthcare environments.

Key facts shared by WHO on Hand Hygiene Day 2016

– 61% of healthcare workers do not clean their hands at the right moment.
– one in two surgical staff do not clean their hands at the right moment.

The secret to good hand hygiene comes not only from knowing how to wash your hands effectively, but from knowing when to wash your hands.

How to Choose an Otoscope

Heine Otoscope & Opthalmoscope

With so many otoscopes to choose from, what’s the difference between a £25 model and one costing ten times as much, if not more? Does it matter what type of light bulb it uses? Should you get an otoscope that uses fibre optics?

To help you answer these questions, we’ve put together this short guide to help you think through selecting the otoscope that’s best suited to your needs and your budget.

Read right to the end, because our summary contains an often-overlooked factor that could make a massive difference to your choice.

Select the most convenient size

Otoscopes come in two different sizes – standard and pocket.

The smallest otoscopes are pen-sized, including a clip to hold them securely in your pocket. Lighter than the full-size models, their construction is normally not as robust, so they’ll probably have a shorter lifespan. Metal pocket clips will generally outlast plastic clips.
