[Diagnosis] Resmed Apnealink Air results

[Squidword]

Hi there,
I recently completed a at home sleep study and i got my results sent to me today.
I understand that these numbers are low but i'm concerned that i'm having them at all.
Can this frequency of events cause symptoms?
I have symptoms:

• Snoring
  
• Dry mouth/throat in morning (tend to mouth breath)
  
• Morning headache
  
• Nighttime sweating
  
• Mild daytime sleepiness 
  
• Nocturia
  
• Nauseous in morning
  
• Restless legs when tired, worse in evenings and relieved by lying down. Lot's of leg movement during sleep.
  

I don't tend to dream (or remember them) when i do dream it's nearly always nightmarish and i wake. 
Can Apnea results be affected by REM sleep disturbances?

Also, any idea why pulse is so eratic? is this normal?
