Some patients with chronic obstructive pulmonary disease (COPD) including chronic bronchitis and emphysema or other long-term conditions can become sensitive to medium or high doses of oxygen.
Too much oxygen can cause a rise in the level of carbon dioxide in your blood and this could make you drowsy or slow your breathing.
This does not happen to all people with these conditions, only a small number. Therefore if oxygen is needed by these people, it should be given in a controlled way and monitored carefully.
We do this by setting target oxygen saturation levels for exacerbations and advise that a Venturi mask is used.
This is a specialised mask that is used to deliver a controlled amount of oxygen. By using this mask it will help to minimise the risk of an increased level of carbon dioxide in your blood.
Your Alert Card.
We have provided you with an alert card as you have been identified as being at risk of oxygen sensitivity.
The alert card is to make sure that doctors, nurses, ambulance staff and the hospital team know that you are sensitive to oxygen.
If you become unwell and require an ambulance, it is important you are given the correct amount of oxygen on your way to the hospital and during your hospital stay. Therefore it is important you show the ambulance staff your oxygen alert card and also take it with you into hospital.
The ambulance staff and hospital team may have been pre-warned that you are sensitive to oxygen.
Your Target Saturations and Venturi Mask.
You have been advised that your target oxygen saturations are ___________ % to ___________ % during exacerbations.
You have been advised that ___________ % Venturi mask should be utilised to achieve the recommended target saturations.
The oxygen flow rate the Venturi mask should be set at ___________ L/min.
The Venturi mask will be used in the ambulance and at the hospital; unless the ambulance staff or hospital team identify the need for a different dose of oxygen when measuring your oxygen saturations
Your oxygen level will be monitored, usually with a finger probe (oximeter) while you are using a Venturi mask.
If the level falls outside your target saturations, the ambulance staff may need to use a different mask or nasal oxygen.
The ambulance staff have been trained to manage this situation
As soon as you are admitted to the hospital, your oxygen and carbon dioxide levels will be measured and oxygen will be given to you appropriately.
Instructions for use.
1. Carry the oxygen alert card at all times. This information is for emergency use only. You may have a different oxygen delivery system for routine use if you are on home oxygen treatment.
2. If you need to call an ambulance or you need to have oxygen whilst visiting your GP, your alert card should be shown to the ambulance staff or to your GP. This will mean they can treat you correctly using the oxygen percentage indicated on the oxygen alert card.
