English

Subject field(s)
  • Respiratory System
DEF

Increase of air in the lungs above the normal amount.

French

Domaine(s)
  • Appareil respiratoire
DEF

Augmentation de la ventilation pulmonaire liée à une augmentation de la fréquence ou de la profondeur des inspirations.

Record 2 2003-10-16

English

Subject field(s)
  • Respiratory System
  • Underwater Diving (Sports)
DEF

... the practice of excessive breathing with an increase in the rate of respiration or an increase in the depth of respiration, or both.

CONT

Hyperventilation is used by divers to reduce the concentration of CO2 and extend the length of breath-holding.

French

Domaine(s)
  • Appareil respiratoire
  • Plongée sous-marine (Sports)
DEF

Accroissement volontaire de la ventilation pulmonaire précédant l'immersion d'un plongeur en apnée.

CONT

Après une hyperventilation, la quantité de CO2 dans le sang est très faible (proche de celle de l'air 0,03%). Il est donc possible de consommer tout l'oxygène avant d'atteindre le seuil de déclenchement du réflexe respiratoire : il y donc syncope anoxique (par manque d'oxygène).

CONT

L'hyperventilation avant l'immersion a pour but de retarder l'apparition de "l'envie de respirer" et de reculer le moment où le seuil de PpCO2 critique sera atteint.

Spanish

Campo(s) temático(s)
  • Aparato respiratorio
  • Buceo (Deportes)
CONT

Forzar repetidamente la respiración antes de una inmersión, técnicamente llamado hiperventilación, no aumenta el oxígeno en los pulmones sino que disminuye la presencia de dióxido de carbono.

CONT

Un método muy empleado para aumentar el tiempo de apnea es la hiperventilación antes de sumergirse, pero la gente que lo hace desconoce los riesgos que está corriendo.

Record 3 1991-03-21

English

Subject field(s)
  • Diagnostic Procedures (Medicine)
  • Bronchi
CONT

To assess the sensitivity of isocapnic hyperventilation with cold air in detecting airway hyperreactivity in asthmatic children, we studied 13 asthmatic patients ... and 10 normal children. Cold air challenge consisted of 4 minutes of moderate hyperventilation plus another 4 minutes of maximal hyperventilation, both with subfreezing air (-16 degrees to -18 degrees C) ... We conclude that exercise and cold air-induced bronchospasm have different physiologic mechanisms, and that cold air testing can be used as a routine challenge to identify airway hyperreactivity in children.

French

Domaine(s)
  • Méthodes diagnostiques (Médecine)

OBS

[On] peut également utiliser un test d'hyperventilation en air sec et froid, fourni par exemple par une bouteille d'air comprimé, qui donnera un résultat analogue, sinon identique à celui de l'épreuve d'exercice.
