Oxygen Therapy

Within this section we will recap the key features of respiration and gas exchange, we will also review oxygen administration and recommendation based on WHO guidance specifically related to COVID -19

By the end of the session the student will be able to:

Recall the mechanism of oxygen transport and gas exchange
Discuss hypoxia and hypercapnia and their effect on other body systems
Describe Type I & Type II respiratory failure
Discuss features of Severe Acute Respiratory Infection
Discuss indications for oxygen therapy
Identify different methods of oxygen delivery
Understand the importance of correct oxygen titration

What you need to do:

We have collated a range of key resources to help you understand key principles and titration of oxygen therapy. Some of the resources we would like you to engage with before your in-class teaching session/web-tutorial; some materials we will be using in class/during the web-tutorial; and some are there for you to explore and return to after the in-class session/web-tutorial.

Before the session:

Please look at the resources in Sections 1 and 3
Please watch the 2 short videos on oxygen therapy in Section 4

During the in-class session

You will need to access these resources

After the session:

Please review Section 2
Familiarise yourself with the additional links and resources provided

Introduction to oxygen therapy 070420.mp4

Section 1

Please watch this short screencast which provides a re-cap on respiration.

Section 2

Below are links to a series of excellcent screencasts by Health Education England and the University of Huddersfield. These Screencasts have been supported by webinars which you can join if you have questions (although some dates are in the past).

Clearly, you are encourged to take a look at all of these training packages but we would particularly like you to focus on the MANAGEMENT OF ACUTE RESPIRATORY SYMPTOMS for this session. Please click on this link and open the presentation, make sure your speaker is on so you get the audio.

Section 3 - Management of SARI

Below is WHO guidance on managing patients with Severe Acute Respiratory Infection (SARI). Most of the content of this session come from this guidance, if you want to have a read through, that maybe useful or use it for your reference if you have any questions. Remember, this is a constantly changing situation so new guidance is coming out all of the time, it's important to keep up to date and we will provide link to help with this at the end of the package.

Please watch the 20 minute screencast which summarises Oxygen therapy in Severe Acute Respiratory Illness

Section 4 - Oxygen delivery

We've described the need to use oxygen and when to do so. Below is a short film about how to deliver oxygen using a range of methods, from nasal cannula to non rebreather mask. This maybe familiar to you but if you need a refresh, take a look. There is also a film about how to give high flow nasal oxygen which is more common when caring for children.

NB. When looking after patients with confirmed or suspected COVID-19 it is important to think about aerosol generation as this can present a danger to the healthcare team. Make sure you are following trust guidance regarding PPE when using specific devices such as high flow systems or humidifed oxygen.

CPAP and BIPAP

Some of you may come across patients who require increased respiratory support. If this is the case, the Trusts you are working in will support you to learn about the equipment they use and the local policies they have but having a basic understanding of Continuous Positive Airway Pressure (CPAP) and Biphasic Positive Airway Pressure (BiPAP) might be useful. Please watch the short film below.

Finally, some patients will require intubation and ventilation within a critical care setting. You are NOT expected to know about this and any training required will be delivered in the Trusts you are working. However, we are aware of some excellent resources available through elearning for health to help NHS staff develop critical care knowledge.

To access these you will need to set up a E learning for Health account. Once you have done this select Coronavirus and then select resources for Staff working in Critical Care.

Thank you for your time, we hope this has been useful, if you have any questions please contact your academic advisor.
