Does Ketoacidosis Cause Hyperventilation

Hyperventilation

Patient professional reference Professional Reference articles are written by UK doctors and are based on research evidence, UK and European Guidelines. They are designed for health professionals to use. You may find the Dealing with Breathing Problems article more useful, or one of our other health articles. The term hyperventilation describes excessive ventilation of the lungs, beyond what is required to achieve normal arterial blood gases. Where hyperventilation occurs chronically or in recurrent episodes and is associated with somatic (respiratory, neurological, intestinal) or psychological (anxiety) symptoms, it is known as hyperventilation syndrome.[1] About 5-10% of general medical outpatients are thought to have this syndrome and, because of the range of somatic symptoms, the risk of misdiagnosis is high. Pathogenesis Hyperventilation has little effect on arterial pO2 and almost no effect on oxygen saturation which is nearly 100% under normal circumstances. Its main effect is to lower pCO2 and produce a respiratory alkalosis. A secondary hypocalcaemia also occurs as calcium dissociation is shifted towards the unionised, bound form. There are many factors that influence the Continue reading >>

    Hyperventilation



    What is it like when someone hyperventilates? Is what I'm experiencing considered hyperventilating?

    Rapid, fast deep breathing is a sign. It can be hyperventilation syndrome, an actual condition where blood gas values, free calcium and pH are out of whack. It can reflect serious pH changes such as in high blood acid states such as ketoacidosis, aspirin overdose, or heavy exercise compensation. It can present with a pulmonary embolism.
    Emotionally, hyperventilation syndrome generally results from/in a great deal of anxiety and it becomes its own snowball effect. Part of this is because true hyperventilation leads to decreased blood flow to the brain and eventual fainting, and it leads to relative hypocalcemia leading to tingling in the lips, cramping or even apparent tonic-like extremity seizures, all of which contribute to more rapid breathing until you finally conk out and reset.
    If you feel the numbness and tingling, it is a good sign you are in respiratory alkalosis and, if combined with a prior history of hyperventilation syndrome, you can probably “relax” knowing it’s that. Try paper bag breathing, breathing in and holding a second, yoga, eating something to force you to down-regulate your breathing.
    Otherwise, if you’re in doubt, go to the hospital or call 911. Be aware many, many paramedics do not understand the difference between hyperventilation syndrome and hyperpnea .
    If you ever develop new, sudden onset rapid breathing and air hunger, especially if it happens a short while after surgery, a broken bone, sitting a long time, calf cramps, or pregnancy or delivery, and you haven’t had a history of psychological problems, that is very possibly a life-threatening condition resulting from a pulmonary embolism. A pulse oximeter like one you can buy online really easy can confirm this by showing your SpO2 is lower than 96%.

    Another cause of gradually increasing rapid deep breathing is if you either a) forget your insulin and your blood sugar creeps way up, or you are diabetic and didn’t know it. In that case the anxiety and tingling should not be there, and your SpO2 will be in the high 90s.
