Question: Relative to Salter labs 2050-50 clear oxygen supply tubing: What is the useful life of the product? Over the last few weeks of June my peripheral oxygen saturation levels were declining. I thought it was a decline in my condition. Then I noticed the relatively weak flow from the nasal cannula. I changed the 50 foot tubing. Flow was noticeably stronger and O2 sats immediately improved. I could not find signs of crushing or kinks. The tubing was probably changed 5 to 6 weeks prior.
