Intro TO Oxygen Assessment And Treatment Flashcards
What is oxygen therapy?
The administration of oxygen at concentrations greater than that in room air, to treat or prevent hypoxaemia, and thereby increasing the availability of oxygen to the body tissues.
What does LTOT, AOT and SBOT stand for?
LONG TERM OXYGEN THERAPY, Ambulatory Oxygen Therapy, Short Burst Oxygen Therapy
What is the aim for LTOT?
Aims to correct chronic hypoxaemia & improve survival in patients with COPD.
Increases life expectancy.
Who should be considered for LTOT?
Stable patients on optimal medical management with SpO2 < 92%, Stable for at least 8 weeks
- Very severe airflow obstruction (FEV 1 < 30% predicted)
• Polycythaemia
• Peripheral oedema
• Pulmonary hypertension
What are the indications(conditions) for LTOT
COPD, CF, Bronchiectasis • ILD • PVD • Primary Pulmonary Hypertension • Pulmonary malignancy • Chronic Heart Failure • Neuromuscular diseases
LTOT is indicated for management of COPD
patients confirmed with chronic hypoxaemia
defined as:
Resting PaO2 < 7.3kPa when stable or
Resting PaO2 7.3-8.0kPa when stable with Secondary polycythaemia
When is LTOT suitable, where the Resting PaO2 is 7.3-8.0kPa when stable?
If the patient has one of the following:
Secondary Polycythaemia
-peripheral oedema
-pulmonary hypertension
What is hypercapnia?
Build up of CO2 in the blood;
↑ PaCO 2 (normal range = 4.8 – 6.0kPa)
• Does not exclude oxygen assessment
How is home oxygen prescribed?
Through a HOOF prescription.
Home oxygen order form
What does an oxygen concentrator do?
Most convenient & economical method of providing domiciliary LTOT
•Most common device for LTOT
•Installed & maintained by oxygen provider companies
Who can be assed for AOT?
- LTOT patients who are mobile
- Non-LTOT patients (PaO2 > 7.3kPa):
- Fall in SpO2 during exercise ( >4% fall, < 90%)
- Correction of hypoxaemia with O2
- Increase in exercise capacity
WHAT are some of the hazards for home oxygen
Tobacco smoking, cooking, candles sparks
