Im sure your exitement may show in your first reading levels Sparklefizz!
Everyone has their own 'normal for them' ranges, its not always the text book 70 beats per min and 98% oxygen saturation level, its amazing what can influence these, even being due for medication to be taken can alter the rate, as can fluid levels and the type of drinks you enjoy, blood sugar levels can also have an effect, especially on heart rate, just dont be too worried if things look a bit out of normal range at first, best check it a couple of times a day over about a week or so and at around the same time, and write the results down to compare at the end of the week, this should give you an idea of what is your own personal normal range, and can be shown to your Doctor or Nurse whenever the need arises for your next appointment or check up. Good Luck
