Bi-Level Positive Airway Pressure for Non-invasive Respiratory Support of Foals.
Abstract: Respiratory insufficiency and pulmonary health are important considerations in equine neonatal care. As the majority of foals are bred for athletic pursuits, strategies for respiratory support of compromised foals are of particular importance. The administration of supplementary oxygen is readily implemented in equine practice settings, but does not address respiratory insufficiency due to inadequate ventilation and is no longer considered optimal care for hypoxia in critical care settings. Non-invasive ventilatory strategies including continuous or bi-level positive airway pressure are effective in human and veterinary studies, and may offer improved respiratory support in equine clinical practice. The current study was conducted to investigate the use of a commercial bi-level positive airway pressure (BiPAP) ventilator, designed for home care of people with obstructive respiratory conditions, for respiratory support of healthy foals with pharmacologically induced respiratory insufficiency. A two sequence (administration of supplementary oxygen with, or without, BiPAP), two phase, cross-over experimental design was used in a prospective study with six foals. Gas exchange and mechanics of breathing (increased tidal volume, decreased respiratory rate and increased peak inspiratory flow) were improved during BiPAP relative to administration of supplementary oxygen alone or prior studies using continuous positive airway pressure, but modest hypercapnia was observed. Clinical observations, pulse oximetry and monitoring of expired carbon dioxide was of limited benefit in identification of foals responding inappropriately to BiPAP, and improved methods to assess and monitor respiratory function are required in foals.

The research article investigates how Bi-Level Positive Airway Pressure (BiPAP) ventilators, typically used on humans with respiratory conditions, can be used to better manage respiratory issues in young horses (foals) with artificially induced respiratory insufficiency.
Overview of the Research
- This research studies the effects of a commercial bi-level positive airway pressure (BiPAP) ventilator—a device typically used for managing obstructive respiratory conditions in humans—on foals suffering from pharmacologically-induced respiratory insufficiency.
- The study is crucial because, in most instances, foals are bred for athletic pursuits and thus, strategies for better respiratory health management in compromised foals is essential.
- The research used a two-sequence, two-phase, cross-over experimental design in a prospective study of six foals. This experimental design allowed for data collection under different conditions: administration of supplementary oxygen with BiPAP and without BiPAP.
Results and Key Findings
- The use of BiPAP lead to improved gas exchange and mechanics of breathing among the foals. This improvement was evident from the increased tidal volume, decreased respiratory rate, and increased peak inspiratory flow.
- The improved outcomes from the use of BiPAP were superior to those observed when supplementary oxygen was administered alone or in prior studies where continuous positive airway pressure was used.
- However, the use of BiPAP resulted in modest hypercapnia, or an excessive amount of carbon dioxide in the blood.
Monitoring and Evaluation Techniques
- Despite the overall improvement in respiratory function, the article notes the limited usefulness of clinical observations, pulse oximetry, and expired carbon dioxide monitoring in identifying foals who responded negatively to BiPAP treatment.
- The research posits the need for improved methods to assess and monitor respiratory function among foals.
Implication of this Study
- This research provides a preliminary indication that BiPAP may offer an effective non-invasive ventilatory strategy for equine neonatal care.
- However, more research is needed to better understand the complications, such as hypercapnia, that may arise from the use of BiPAP in foals.
- Additionally, the research proposes the urgency for better methods of monitoring and assessing respiratory function in foals.
