Oxygen therapy should be applied in each case of hypoxy.The level of arterial oxygen must always be measurement (by test of arterial blood gases), to see the levels of oxygen in the blood and to determine the grade of hypoxy .The partial pressure of oxygen blood measured in columns mercury (mmHg) and normal price is more than 85 mmHg.

* Less than 60 mmHg there is respiratory failure
* Less than 45 mmHg is considered severe and requires immediate therapy with oxygen

The objective is to achieve levels of oxygen in the blood at least 60-70 mmHg

The hypoxia causes:

* Damage to various organs
* Limiting the patient both in work and everyday drastirotites
* Reduces the survival

There are diseases that can cause hypoxia or transient respiratory failure, as eg pneumonia, which after removal of the cause (eg treatment of pneumonia), restored and normalized the hypoxia and the patient no further oxygen .

There are diseases that causes chronic hypoxia and thus require chronic administration oxygonou.Ta diseases are mainly:

* Chronic Obstructive Pulmonary Disease
* Primary pulmonary hypertension
* Heart failure
* Chronic diseases of the chest wall
Interstitial lung disease *
* Recurrent pulmonary embolism
* Pnefmonektomi

The criteria to put the patient on chronic oxygen therapy are:

1. oxygen levels below 55 mmHg
2. if levels are between 55-60 mmHg and coexist

* Polyerythraimia
* Right heart failure
* Pulmonary hypertension

The duration of oxygen therapy should be at least 16 hours 24/oro, including hours of sleep.

NB: Should we check every quarter or month to determine the levels of oxygen and adjusted to provide if required.

Sources for oxygen there are 2 types: large bottle (fig.1), capacitor (Fig.2). Also, the benefit becomes or nasal catheter (glasses) (fig.3) or mask (eik.4)

eik.1, eik2, eik.3, eik.4

There are small oxygen tanks, which are easy on the movements of patients (eik.5)
