  • Hyperventilation

    […] or giddiness, profuse perspiration, and tingling sensations in the fingertips, face, or toes.[medical-dictionary.thefreedictionary.com] In this case, we found capnography to be a very useful aid to monitor respiration in this patient and also to treat the hypocapnia.[ncbi.nlm.nih.gov] […] examined whether slower pulmonary O 2 uptake (V O 2p ) kinetics in hypoxia is a consequence of: a) hypoxia alone (lowered arterial O 2 pressure), b) hyperventilation-induced hypocapnia[ncbi.nlm.nih.gov]

  • Acute Hyperventilation

    Abstract Acute hypocapnia decreases CBF, increases hemoglobin affinity for oxygen and causes cerebral tissue hypoxia.[ncbi.nlm.nih.gov] They will also be taught in a practical way to recognize early clinical signs and symptoms of hypocapnia.[clinicaltrials.gov] Granholm L, Siesjö BK (1969) The effects of hypercapnia and hypocapnia upon cerebrospinal fluid lactate and pyruvate concentrations and upon the lactate, pyruvate, ATP, ADP[link.springer.com]
