Medical - Medical (general) / Blood pressure | | Greek term or phrase: μυικός μόχθος | | εξωτερικός παράγοντας που αυξάνει την αρτηριακή πίεση. |
| | | muscular effort | Explanation:
Spirometry should be looked upon as a simple expression of a complex process just as with blood pressure. All primary care physicians need to understand the essence of spirometry, and this can be easily taught. The lungs are filled by muscular effort, and in the normal state, there is a uniform distribution of ventilation. Expiratory airflow is a function of muscular force, elastic recoil, large airways function, small airways function and interdependence. Conventional spirometry measures volume over time. A second convention measures flow over volume. Both expressions measure exactly the same thing but express it in a different way. NLHEP recommends only two parameter spirometry, (i.e., FEV1, FVC and the ratio between the two). The normal ratio is greater than 70%. Since normal lungs empty in six seconds or less, the FEV6 has become the surrogate for FVC.

There are several possible mechanisms for the acute rise in blood pressure with each apnea: lack of oxygen, stimulating chemoreceptors which increase activity of the heart and blood vessels; acute arousal from sleep itself; the extra muscular effort required to overcome the obstruction; and increased pressure within the thorax. However, the same type of blood pressure rise occurs with central apneas, suggesting that lack of oxygen may be the most important factor, or at least more important the increased muscular effort or thoracic pressure. The greater the oxygen desaturation, the more the blood pressure changes. Also, supplemental oxygen alleviates these blood pressure rises.
