Dogs can have sleep apnoea too
Newswise — Researchers from the University of Helsinki conducted a trial on a novel technique for detecting sleep-disordered breathing in canines. They employed a neckband specifically designed for diagnosing sleep apnea in humans. The findings demonstrated a higher occurrence of sleep-disordered breathing in dogs with shorter snouts compared to those with lengthier snouts.
French bulldogs, pugs, and other brachycephalic canine breeds enjoy widespread popularity as pets. These breeds possess a distinct characteristic of having shorter noses and flatter faces, which are the outcomes of selective breeding. However, this particular physical trait renders them more vulnerable to challenges such as heat sensitivity, excessive exertion, and respiratory issues.
Furthermore, it has been discovered that brachycephalic dogs experience recurrent occurrences of sleep-disordered breathing, which closely resemble the obstructive sleep apnea found in humans due to upper airway blockage. These episodes entail interruptions in regular breathing as the upper airway muscles relax, leading to disrupted sleep patterns and daytime exhaustion. Sleep apnea can significantly affect the overall well-being of both humans and canines alike.
"Sleep apnea poses a significant risk for individuals, increasing their susceptibility to conditions like hypertension and cardiovascular disease. Sleep plays a crucial role in regulating the immune system, hormone secretion, and metabolism within the body. The importance of obtaining adequate and restful sleep cannot be overstated when it comes to maintaining a good quality of life. Due to these reasons, among others, we have a keen interest in studying the sleep patterns of canines," explains Dr. Iida Niinikoski, a Doctoral Researcher at the Faculty of Veterinary Medicine, University of Helsinki.
"Traditional approaches to studying sleep apnea in dogs have involved subjecting them to various equipment while they sleep or confining them to specific types of boxes within a laboratory setting. These methods have posed significant challenges and restricted our understanding of sleep apnea in dogs."
The Lung Insight research group at the University of Helsinki conducted an investigation into sleep-related breathing patterns in dogs by utilizing a neckband system initially developed for diagnosing sleep apnea in humans.
The neckband system has been discovered as a convenient technique for measuring sleep-disordered breathing. While its current application is restricted to research patients, it holds potential for exploring novel avenues in diagnosing dog sleep apnea in various settings as well.
Next, the research group will explore factors predisposing dogs to sleep apnoea.
As Niinikoski believes, “Good sleep is vital for the health of both humans and our animal friends.”
