I have a few questions about pulse oximetry if anyone can help please?
- Why do I get different readings from different fingers? Which finger is best?
- Why do my sats rise while I talk, regardless of my breathlessness?
- Why do my sats plummet when I stop talking/lie down after a short walk/hold my breath for only a few seconds?
- Side question: What is a normal breathing pattern? Inhale/Exhale how long? Should I be able to hear my own breathing or feel the coolness of air in my throat?
I have mild asthma and an upper airway obstruction that causes choking in my sleep, for the record-! Sorry for so many questions, can't find the answers!
