HCC Oxygen

Question 1

Why use Oxygen Therapy?

Answer 1

Respiratory failure (Type 1 or 2) who have hypoxia (low levels of oxygen in body tissues)

Question 2

Hypoxia

Answer 2

Low levels of O2 in the tissues

Question 3

Benefits of O2 Therapy

Answer 3

-Live saving for hypodermic patients
-O2 reduces work of breathing
-Decreases myocardial workload (stress put on heart muscle)

Question 4

Too much O2 can be bad

Answer 4

It drives up CO2 levels
This is dangerous in patients with COPD

Question 5

O2 drug that should be prescribed

Answer 5

Registered nurse should understand how to give it effectively

Question 6

Target O2 saturation levels

Answer 6

-Most Patients 94%-98%
-COPD or CO2 retaining patients 88%-92%

Question 7

My Role

Answer 7

-Monitor O2 minimum every 4hrs
-Record SatO2 as part of EWS including device
-Care ofpatient whilst in progress
_provide mouth care if needed

Question 8

Devices used to administer O2

Answer 8

-Nasal cannulae
-Low flow O2 via face mask/Venturi mask
-Tracheostomy mask
-Nebulisers
-Non rebreathing mask and reservoir bag

Question 9

Nasal Cannulae (N)

Answer 9

Recommended for most
CO2 not rebreathed
Limited level of O2 delivery
Mouth breathing = little O2 inspired

Question 10

Simple face mask (SM)

Answer 10

Medium conc O2
Used Type 1 Respiratory failure
Variable O2 conc 35%-60%
Eat/drink limited
CO@ rebreathing

Question 11

Monitoring

Answer 11

Respiratory rate
Observations of skin colour
Escalate signs of respiratory distress
Check mouth,nose and behind ears
Record obser every 4hrs for constant O2, 8hrs for intermittent

Question 12

Care

Answer 12

O2 dries airway (oral fluid, water based lipbalm, mouth care)
Skin at risk of pressure damage(behind ears, nose,nostrils
Position (sit upright)
Devices fitted correctly

Question 13

Health and Safety

Answer 13

Wall mounted O2 turned off when not in use
Portable ylinders stored safely
