My husband used his CPAP machine for the first time this week, with pressure set at 16. When he woke up in the morning, he started vomiting violently, had a severe headache and severe vertigo. He was in such distress that I called an ambulance.
Dear Lisa and Lisa's hubby,
You have assumed that the fact that the CPAP was used for the first time and had vertigo, nausea amd vomiting and head ache the next day. so the CPAP must be the cause for all that followed and you are probably right too.
I'd like to think outside the box just to make sure you are not barking up the wrong tree.
What if all these did not have anything to do with the CPAP and were just a coincidence ?
Assumning you are using a nose mask. If the pressure is as high as 16 it is reasonable to assume that the apnea is severe. Now the question is whether the apnea is Obstructive apnea or Central apnea. If it is just obstructive apnea if the pressure is too high one cannot breathe against this high pressure and automatically as a reflex action will exhale through the mouth and within a few minutes one would remove the mask for good as it is not possible to breathe if the pressure was too high.
I tend to believe that if your apnea could be central apnea. then symptoms like nausea, headache, vertigo vomiting etc are are nurological issues including ear ache and ringing in the ears. It is common knowledge that apnea patients have a high risk for hypertension as well as stroke. From this point of view I believe that you should ask your doctors to do a doppler ( ultrasound) of the arteries of the neck to make sure thre are no blockages especially in the vertebral arteries that run through the cervical spine feeding the PICA ( posterior Inferior Cerebellar Artery) which in turn supplies blood to the part of the brain stem that controls the autonomous system including breathing, swallowing, hearing, speech, vision etc etc...
I am not suggesting I am correct but we need to rule out TIA ( transient Ischemic attack ) that is a precurser to a stroke as a TIA could give all the mentioned symptoms.
I have suffered from sleep apnea since 1989 and suffered a brain stem stroke in 2000 caused by a blocked vertebral artery. So I know from personal experience besides some of the above symptoms I also used to have migraines with visual disturbances. My doctors failed to diagnose my condition and even labelled me a hypocondriac. On 7th April 2000 I was rushed to emergency and was sent home after being told I had a migraine. On 13th April 2000 I suffered a massive stroke in my sleep at 4.00am I lost a ton but have regained most and have recovered 95%. Thank God for that.
Yes a doppler of the neck arteries is necessary to rule out a TIA.
