Correlação entre a capacidade vital lenta e o tempo máximo de fonação em idosos

Abstract

Purposes: to verify the existing relationship between the slow vital capacity and maximum phonation time in the elderly. Methods: the study was analytical and observational, cross-sectional, conducted at the Open University Senior Citizens at the origin institution, in the period from June to October 2014, with 61 elderly female, nonsmokers. We excluded patients with chronic obstructive pulmonary disease and / or respiratory diseases, individuals with neurological or hearing problems and voice professionals. All participants were assessed for slow vital capacity and maximum phonation time. The following data were also collected: gender, weight, height, age and body mass index. Results: the results showed that the values of slow vital capacity and maximum phonation time are reduced in the elderly. In addition, there is a positive correlation between the slow vital capacity and maximum phonation time of / s / and / z /. Conclusion: with aging, breathing and voice measures may be reduced. In addition, there is an association between the slow vital capacity and maximum phonation time in older women, suggesting the influence that breathing exercises over phonation in this specific population.

Single breath counting technique to assess pulmonary function: a systematic review and meta-analysis

“…The selected articles included one diagnostic accuracy study [8], one concordance study [15], seven crosssectional [12,13,16,[39][40][41][42], and two that did not inform the design [43,44]. They were conducted in five countries, Brazil [8,12,15,16,40,42], Saudi Arabia [41], Argentina [39], Germany [43] and the USA [13,44]. The age of participants was wide across studies, ranging from 12 to 59 years.…”

“…The age of participants was wide across studies, ranging from 12 to 59 years. The profile of patients was different; four studies involved hospitalized patients [8,12,16,40] including one with a patient in the postoperative period of cardiac surgery [40] and four studies with patients with neuromuscular diseases [39,41,43,44], and two exclusively with healthy individuals [15,42] and one with children [13] (table 2).…”

“…Table 2 summarizes the main findings of the pulmonary function assessment protocol. As for the reference test, three studies used a ventilometer [16,40,42], and the others used a spirometer, of which only two [39,41] described calibration procedures. Vital capacity was evaluated as the main lung function variable in all studies.…”

“…Vital capacity was evaluated as the main lung function variable in all studies. Five studies adopted FVC [13,39,41,43,44], six studies adopted SVC [8,12,15,16,40,42] and note that all the SVC studies were conducted in Brazil.…”

“…As lung function is directly related to voice production, individuals with limited lung functionality may have altered SBCT [8,[11][12][13][14]. There is evidence that this technique presents a good correlation, reproducibility [15] and accuracy [8] with the standard values of spirometry, mainly with the VC [12,13,16]. Most adults with normal ventilatory function are able to count to 50 in a single breath.…”
