Popular Devices for Oxygen Therapy

 Oxygen or O2 therapy is the administration of concentrated levels of oxygen to
patients suffering from acute or long-term medical conditions

 The concentration of the oxygen is greater than that of the ambient air
 The prevention of the symptoms and manifestations of hypoxia are one of the

major reasons for the therapy
 Oxygen therapy is also useful for people with chronic lung diseases like Chronic

Obstructive Pulmonary Disease (COPD)

Heady trauma, Injury or Acute Tachypnea

 In case the respiratory rate climbs beyond the normal i.e. 12-24 breaths per
minute (bpm)

 Significant increase is marked by 30+ bpm

Acute Tachycardia

 If the myocardial rate reached more than 60 – 100 beats per minute (bpm)
 Significant increase is marked by 110 bpm
 Oxygen Saturation Level decrease
 Significant decrease is marked when below 85
 Normal levels are 90-100 SpO2

Devices used to administer oxygen with varying levels of concentration

Device – Nasal canula

 Nasal canula is a tubular devise with protruding prongs to be inserted into the nostrils
 It is connected to a source of oxygen and it is disposable
 Inspiratory Oxygen Fraction (FlO2) of 24-44% is delivered by a standard nasal canula

Advantage:

 Patients can eat and talk while taking oxygen
 Can be easily used at home

Disadvantage:

 May cause discomfort to the to the nasal and pharyngeal mucosa

High flow devices intake air through the sides to administers high concentrations of O2

Device - Venturi Mask

 The mask is made to inlet a constant flow of the ambient air with a fixed
concentration of oxygen

 Designed with wide-bore tubing

Advantage:

 Delivers the most precise amounts of oxygen
 Doesn’t dry out mucous membranes

Disadvantage:

 Uncomfortable and may cause skin irritation
 It may cause respiratory depression
