Nasal Airflow during Respiratory Cycle

American Journal of Rhinology, 2006
Background Knowledge on the airflow patterns in the nasal cavity is essential to understanding the function of the nasal cavity. This study has attempted to observe the breath cycle of nasal airflow during respiration at rest.

Nitric oxide in the human respiratory cycle

Nature Medicine, 2002
Interactions of nitric oxide (NO) with hemoglobin (Hb) could regulate the uptake and delivery of oxygen (O(2)) by subserving the classical physiological responses of hypoxic vasodilation and hyperoxic vasconstriction in the human respiratory cycle.

Nervous Activity in Relation to the Respiratory Cycle

Nature, 1961
IN the intact organism the physiological systems should show varying degrees of integration and interaction. Respiration is a cycle which appears likely to bear some relationship to moment-to-moment activity of the nervous system, because of its general biochemical effects, its wide afferent and efferent connexions, and its association with the brain ...

Time relationship between the respiratory cycle and limb cycle in the horse

Equine Veterinary Journal, 1982
Summary Techniques developed for the detection and simultaneous recording of certain events in the respiratory and limb cycles are presented. The respiratory cycle and limb cycle were found to be in‐phase only at the canter and gallop.

Effects of the Menstrual Cycle on Respiratory Muscle Function

American Review of Respiratory Disease, 1989
Abstract To investigate the effect of the menstrual cycle on respiratory muscle function, respiratory muscle and pulmonary functions were measured and compared in the midfollicular phase and in the midluteal phase of the menstrual cycle in 30 healthy adult women.

Respiratory Mechanical and Cardiorespiratory Consequences of Cycling with Aerobars

Medicine & Science in Sports & Exercise, 2017
Aerobars place a cyclist in a position where the trunk is flexed forward and the elbows are close to the midline of the body. This position is known to improve cycling aerodynamics and time trial race performance compared with upright cycling positions.

Respiratory Control, Respiratory Sensations and Cycling Endurance After Respiratory Muscle Endurance Training

2008
Respiratory muscle endurance training (RMET) was shown to increase endurance performance in healthy subjects. Reduced adverse respiratory sensations might contribute to this improvement. In the present study, we aimed to assess the relationship between changes in respiratory sensations and changes in ventilation and endurance performance after RMET ...

Influences of Respiratory Cycle on Simple Reaction Time

Perceptual and Motor Skills, 1965
The effect of respiration on simple auditory reaction time was studied. In the first study, reaction times and respiratory phase data were collected during spontaneous breathing; in Study 2, a warning light signaled S to hold his breath in either inspiration or expiration. Both experiments showed faster reaction times with expiration.

Automated respiratory cycles selection is highly specific and improves respiratory mechanics analysis

Pediatric Critical Care Medicine, 2012
Selected optimal respiratory cycles should allow calculation of respiratory mechanic parameters focusing on patient-ventilator interaction. New computer software automatically selecting optimal breaths and respiratory mechanics derived from those cycles are evaluated.Retrospective study.University level III neonatal intensive care unit.Ten mins ...

The effects of emotional behaviour on components of the respiratory cycle

Biological Psychology, 1998
The present study was designed to examine affect-related respiratory responses during film scenes, reaction time (RT) and cold pressor (CP) tasks. In addition, I investigated whether affect-related respiratory responses could be characterised by a number of underlying dimensions, such as positive versus negative affect and active versus passive coping.
