A Low‐Cost, Handheld Optical Stiffness Sensor for Minimally Invasive Surgery

open access: yesAdvanced Robotics Research, EarlyView.
A novel handheld stiffness sensor is presented for real‐time tissue stiffness characterization. By simultaneously sensing contact force and tissue deformation, the device enables accurate stiffness quantification without requiring precise manual control. This approach offers a promising solution for intraoperative tumor detection and minimally invasive

Forced Vital Capacity, Slow Vital Capacity, or Inspiratory Vital Capacity: Which Is the Best Measure of Vital Capacity?

Journal of Asthma, 1998
Vital capacity can be measured as forced vital capacity (FVC), slow vital capacity (SVC), and inspiratory vital capacity (IVC). Although it is well known that the latter two are generally greater, a systematic comparison of the three in subjects with different degrees of airways obstruction has not been made.

Effect of posture on vital capacity

Journal of Applied Physiology, 1986
The influence of some extreme body postures on vital capacity (VC) was examined in young adult humans. Two postures required full support of body weight by the arms: arms up, hanging from a bar, and arms down with hands gripping parallel bars. Three involved muscles that flex and extend the trunk: a partial sit-up position while supine and nearly ...

The Vital Capacity in Pulmonary Emphysema

Annals of Internal Medicine, 1964
Excerpt It is commonly believed that the vital capacity of patients with obstructive or bullous pulmonary emphysema is more or less diminished; mild emphysema is supposed to be accompanied by sligh...

Fall in vital capacity with posture

British Journal of Diseases of the Chest, 1985
In a study of 147 subjects (50 normals, 50 with obstructive, and 47 with restrictive lung function), the mean reduction in forced vital capacity from standing to supine (delta FVC) was 7.5% (SD +/- 5.7), 11.2% (+/- 13.4), and 8.2% (+/- 7.7) respectively, with no significant difference between groups. The respective 95% upper confidence limits were 19%,

VITAL CAPACITY

Archives of Internal Medicine, 1927
It has been recognized that climates with a low relative humidity give relief to some patients with asthma. Inferentially this is due, at least in part, to the beneficial effect of dry air, which will extract more moisture from the bronchial tree than the air of a locality with a higher humidity.
