One of the true pleasures of having a pulse oxymeter at home is those wonderful nights when it decides not to “pick up”. Nothing excites Karin and I more than staying up through the night pushing the silence alarm button every three minutes because although Liam is doing just fine the notoriously unreliable piece of equipment just reads blanks. Kind of hard for Liam to be moving around so much if his heart rate is in the teens and pulse ox at a nice robust 32. At least the ear piercing alarm that sounds every three minutes is a nice soothing tone like the comforting vibrations of a dentists drill. How could we not sleep through that?
