Relation of Hypoxemia and/or Hypocapnia to Lactic Acid Content of Brain and Cardiovascular Response

open access: yes, 1958
The lactic acid concentration of brain was measured 3 hours after death in dogs which had been subject to hypocapnia, hypoxemia with hypocapnia, and hypoxemia without hypocapnia for 15 minutes.

Ventilatory effects of specific carotid body hypocapnia in dogs during wakefulness and sleep

open access: yes, 1995
We used extracorporeal perfusion of the vascularly isolated carotid sinus region to determine the effects of specific carotid body chemoreceptor hypocapnia-alkalosis on ventilatory control in the unanesthetized dog. Eight female dogs were studied during

HYPERVENTILATION HYPOCAPNIA AS THE LEONARDO DA VINCI’S SYNDROME [PDF]

open access: yes, 2019
The paper in early history of pulmonary medicine deals with studies of hypocapnia as a result of hyperventilation. Hyperventilation hypocapnia provokes respiratory alkalosis, subsequent ion changes in blood may cause disorders of myocardium ...

Adaptation of rabbit renal cortical Na+-H+ exchange activity in chronic hypocapnia

open access: yes, 1989
We have examined the activity and kinetic characteristics of the Na+-H+ exchanger in renal cortical brush-border membrane vesicles (BBMV) prepared from rabbits adapted to chronic hypocapnia in order to address whether this transporter might contribute ...

pCO2 values in asphyxiated infants under therapeutic hypothermia after tailored respiratory management: a retrospective cohort study

open access: yesFrontiers in Pediatrics
BackgroundHypoxic-ischemic encephalopathy (HIE) represents one of the major causes of neonatal death and long-term neurological disability. Both hypoxic-ischemic insults and therapeutic hypothermia (TH) can affect respiratory function.

Hyperventilation and seizures in an adolescent female

open access: yesMonaldi Archives for Chest Disease, 2015
A 16 year-old girl was admitted after suffering from recurrent episodes of dyspnea and stridor, cyanosis, loss of contact, stiffening of all four limbs, clenching of the jaw and eye retroversion that lasted for a few seconds to a minute, followed by slow

Tachykinins mediate hypocapnia-induced bronchoconstriction in guinea pigs

open access: yes, 1989
The aim of this study was to determine whether hypocapnia causes bronchoconstriction by releasing tachykinins (TKs) from C-afferent nerves in airways.

Non-pulsatile blood flow is associated with enhanced cerebrovascular carbon dioxide reactivity and an attenuated relationship between cerebral blood flow and regional brain oxygenation

open access: yesCritical Care, 2019
Background Systemic blood flow in patients on extracorporeal assist devices is frequently not or only minimally pulsatile. Loss of pulsatile brain perfusion, however, has been implicated in neurological complications.

A comparison of dynamic cerebral autoregulation across changes in cerebral blood flow velocity for 200 seconds

open access: yesFrontiers in Physiology, 2014
Objectives: The dynamic interaction between blood pressure (BP) and cerebral blood flow velocity (CBFV) is not fully understood, especially for CBFV changes lasting longer than 50 s.

Effects of methacholine and hypocapnia on airways and collateral ventilation in dogs

open access: yes, 1979
We studied the effects of hypocapnia and methacholine on small airways resistance (Rsaw) and collateral ventilation in anesthetized paralyzed dogs.
