Background: Body posture refers to the position of a person’s body in space, the alignment of body parts in relationship to one another and to the environment at one point in time. Different postures such as forward head posture and kyphosis have been shown to alter breathing mechanism. Pulmonary function test is an important tool in the investigation of patients with respiratory pathology. Methods: A comparative study was conducted at vikhe patil memorial hospital and college, Ahmednagar. The craniovertebral angle and Pulmonary function test was taken on 40 adults.

Asthma is usually diagnosed clinically. This study investigated how methacholine challenge and peak expiratory flow monitoring influenced change from a pretest clinical diagnosis. Records of 132 patients referred with respiratory symptoms, who subsequently had reliable measurements of both airway responsiveness (provocative concentration of methacholine causing a 20% fall in forced expiratory volume in one second (FEV1 (PC20)) and peak expiratory flow variability (PEFV) were reviewed. Initial and final diagnoses for each patient were classified as: a) definite asthma; b) possible asthma; and c

Abstract:
Exercise-induced bronchoconstriction (EIB) is a dysfunction of the respiratory tract consisting of transient airflow obstruction. This study is a retrospective analysis of two prospective studies concerning EIB symptoms in two adolescent populations. Our study group included 400 non-athletes and 101 athletes. Due to the similarity of indoor exercise conditions, an analysis was performed on the basis of where training took place. The study aims to assess the EIB prevalence in the following groups of adolescent children: non-athletes and athletes. In “indoor” athletes, the EIB prevalence was 22.

Background: The events in pregnancy elicit one of the best examples of selective anatomical, physiological and biochemical adaptations, with profound changes in respiratory physiology. The changes in respiratory physiology are due to increased size of the fetus with advance gestation which constitutes a mechanical impediment to normal process of ventilation.

Abstract:
The upper airway is anatomically defined by the carina inferiorly and pharynx superiorly, with pathology predominately arising from the trachea and larynx. Obstruction of the upper airway may arise because of a fixed structural pathology such as tracheal stenosis or malignancy, but can arise following loss of normal function (e.g. inappropriate vocal cord adduction). A high index of suspicion is required to make the diagnosis because the clinical features of upper airway obstruction can mimic other respiratory conditions.

Abstract:
This chapter describes how additional information can be obtained during an exercise test to detect the airflow obstruction of exercise-induced asthma. The forced expiratory volume in one second (FEV1) may fall a few minutes after cessation of exercise, but this test is not particularly sensitive for detecting exercise-induced bronchoconstriction. The flow–volume loop during exercise can be compared with the pre-test maximal trace to detect expiratory airflow limitation. Addition of inspiratory capacity measurements can be helpful. The flow–volume loop may also suggest exercise-induced larynge

Abstract:
This chapter describes how the amount of air going in and out of the lungs increases on exercise. The predicted value for minute ventilation (VE) is calculated for each subject from their own forced expiratory volume in one second (FEV1), rather than taken from published tables. Normally, ventilation does not limit exercise and VE does not reach 80% of the predicted value. If VE at peak exercise is more than 80% of predicted, it is likely there is something wrong with the lungs. VE increases by a combination of a larger tidal volume and an increase in breathing frequency. The pattern of increa
