AHI counts scored breathing events per hour, while oxygen desaturation index counts oxygen-drop events per hour. Learn how both numbers fit into sleep apnea reports and overnight SpO2 trend monitoring.
Overnight oxygen saturation trends can show patterns worth discussing with a clinician, but they do not diagnose sleep apnea on their own.
A home sleep apnea test can miss some cases of obstructive sleep apnea. Here is when an in-lab study may be the better next step and how overnight oxygen trends fit into follow-up.
Persistent sleepiness after starting CPAP does not automatically mean treatment has failed. Learn what adherence, mask leaks, sleep time, PAP data, and other possible causes can reveal.
Late July 2026 smoke and heat alerts in Canada are raising indoor-air questions. This article explains how cooling, AQHI guidance, and limited pulse oximeter checks fit together and where they do not.
Positional sleep apnea becomes more severe while sleeping on the back. Learn when side sleeping and positional therapy may complement professionally prescribed care.
Canada’s summer 2026 outlook points to hotter conditions. This article explains where a pulse oximeter can help during heat alerts and where it cannot replace symptom awareness or public-health guidance.
CPAP remains a common sleep apnea treatment, but alternatives such as oral appliances, positional therapy, weight management, surgery, and implanted stimulation may fit selected patients.
Canada’s summer outlook points to higher wildfire risk and warmer temperatures. This article explains how to use AQHI alerts and where pulse oximeters fit, and do not fit, during smoke events.
Zepbound is a newer prescription option for some adults with obstructive sleep apnea and obesity, but it does not replace CPAP, professional sleep testing, or clinician follow-up. Learn where overnight oxygen monitoring fits.
