Insights
Infants needing nasal continuous airway pressure at 34 weeks
Area of Science:
- Neonatal Medicine
- Pediatric Respiratory Care
Background:
- Premature infants often require respiratory support after birth.
- Predicting the need for home oxygen therapy is crucial for discharge planning.
Purpose of the Study:
- To identify a predictor for home oxygen therapy needs in preterm infants.
- To determine if respiratory support level at 34 weeks' postmenstrual age (PMA) predicts home oxygen use.
Main Methods:
- Retrospective study of 143 infants born before 28 weeks' gestation.
- Analysis of respiratory support weaning timelines (mechanical ventilation, nCPAP, nasal cannula).
- Primary outcome: need for home oxygen therapy.
Main Results:
- Infants requiring nasal continuous positive airway pressure (nCPAP) at 34 weeks' PMA had a 100% positive predictive value for home oxygen.
Conclusions:
- Respiratory support level at 34 weeks' PMA accurately predicts home oxygen needs.
- This predictor aids in preparing infants and families for discharge.
Objective:
To discover a predictor, that could be used at least 3 to 4 weeks' before discharge, to identify infants who would need home oxygen therapy. We hypothesized that infants requiring a high level of respiratory support at 34 weeks' postmenstrual age (PMA) would require home oxygen.
Study Design:
Single center retrospective study of 143 infants less than 28 weeks' gestation. We determined when infants weaned from each level of respiratory support (mechanical ventilation, nasal continuous airway pressure [nCPAP] or biphasic positive pressure, nasal cannula flow ≥ 2 L/min, nasal cannula flow < 2 L/min or no respiratory support). Our primary outcome was need for home oxygen.
Result:
Infants who required nCPAP at 34 weeks' PMA had a 100% positive predictive value for home oxygen therapy.
Conclusion:
Higher levels of respiratory support at 34 weeks' PMA can predict the need for home oxygen and is useful in preparing patients and families for discharge.

Respiratory Assessment: Purpose and Indications
Objectives and Importance:
The primary goal of respiratory assessment is to evaluate patients at early risk of clinical deterioration. Since respiratory distress often precedes other signs of declining health, breathing patterns and sounds become a...
Administering Oxygen by Mask
Administering oxygen by mask is a common nursing intervention that provides supplemental oxygen to patients with respiratory distress or chronic lung conditions. This procedure involves delivering oxygen at a specified rate through a face mask connected to an oxygen source.
Equipment
The equipment necessary for this procedure includes:
Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
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,...

Oxygen Delivering System I: Nasal Cannula and Face Mask
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.
Oxygen percentage setting:...
