Oxygen therapy for children with acute respiratory infections in small hospitals
1Department of Paediatrics and Child Health, Faculty of Medicine, Addis Ababa University, Addis Ababa.
Insights
Oxygen therapy is crucial for hypoxemia, but accessibility is limited in developing nations. This review details oxygen sources, administration methods, and clinical indications for its use in children.
Area of Science:
- Medical Sciences
- Respiratory Medicine
- Pediatrics
Background:
- Hypoxemia management is vital for preventing death and disability from common illnesses.
- Oxygen therapy is essential but often unaffordable in developing countries.
- Limited guidance exists for healthcare professionals on oxygen therapy initiation, administration, and sourcing.
Purpose of the Study:
- To review literature on indications for initiating and discontinuing oxygen therapy.
- To compare oxygen sources (cylinders vs. concentrators) for small hospitals.
- To evaluate efficient and safe oxygen administration methods.
Main Methods:
- Literature review using Medline citations and cross-references.
- Analysis of evidence for clinical indications and administration techniques.
- Comparison of oxygen cylinder and concentrator systems.
Main Results:
- Oxygen therapy is indicated in children with cyanosis, chest indrawing, feeding difficulties, tachypnea (>70/min), or restlessness improving with oxygen.
- Oxygen concentrators have high initial costs but low running costs and no transport needs.
- Oxygen cylinders are costly to transport and require frequent refilling.
- Nasal prongs are the safest administration method, followed by nasal catheters.
Conclusions:
- Evidence-based guidelines for oxygen therapy are needed, especially in resource-limited settings.
- Oxygen concentrators offer a potentially more sustainable solution than cylinders for small hospitals.
- Safe and effective oxygen administration protocols are crucial for pediatric hypoxemia management.
Abstract:
Oxygen administration is one of the most important modalities of therapy for a patient with hypoxaemia to prevent death and disability from common conditions such as acute lower respiratory tract infections. Oxygen needs to be available at all times in hospitals, however, it is too expensive for many developing countries. There is little information for health professionals regarding indications for initiating oxygen therapy, selecting appropriate method of oxygen administration and deciding on the source for oxygen. A review of the literature using medline citations and cross references from published articles and other manuscripts was made. The review described the two main sources of oxygen for small hospital-cylinders and oxygen concentrators and their advantages and disadvantages. It also looked at the evidences for clinical indications to initiate and discontinue oxygen therapy. Studies on efficient and safe methods of administration of oxygen were reviewed as well. The review concluded that oxygen may be administered in children with cyanosis, chest indrawing, inability to drink or breastfeed, tachypnea with respiratory rate above 70/minute or in a child who develops restlessness and improves on oxygen. The initial capital cost of concentrators is high but the running cost is low and it does not require transport while oxygen cylinders are expensive to transport and need continuous refilling. The safest method of oxygen administration are the prongs followed by the nasal catheters.

Nasal Cannula
A nasal cannula is a lightweight tube split at one end into two prongs and placed in the nostrils. It is typically used to deliver low to medium levels of oxygen.
Suggested flow rate: The suggested flow rate for a nasal cannula typically ranges between 1 and 6 L/min.

Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...
