Bronchial suction

Selective placement of bronchial suction catheters in intubated neonates.

Flexible suction catheters were passed through the endotracheal tubes of infants undergoing mechanical ventilation, just before chest radiographic examination for clinical purposes. With the head straight, 7 of 10 straight catheters entered the right main bronchus but with the head turned, 17 of 20 straight catheters and 19 of 20 curved tip catheters entered the contralateral bronchus.

Suction is kid's play: extremely fast suction in newborn seahorses.

Ongoing anatomical development typically results in a gradual maturation of the feeding movements from larval to adult fishes. Adult seahorses are known to capture prey by rotating their long-snouted head extremely quickly towards prey, followed by powerful suction. This type of suction is powered by elastic recoil and requires very precise coordination of the movements of the associated feedin...

Suction spectrophotometer cell.

A spectrophotometer cuvet is described which is emptied by suction without removal from the instrument. The use of this cuvet saves time and minimizes the chance of breakage. Data from C " measurements and absorbances of a dye solution show minimal retention error from successive specimens. expended in determining the absonbances of a large series of individual samples in a spectrophotometer ca...

Axisymmetric Suction Flow 3

Gastro-intestinal suction.

During recent years the many indications from reports in the surgical literature, and the reduction of the mortality from abdominal injuries of warfare, have indicated that gastro-intestinal suction can play a major role in reducing the mortality rate in a great number of surgical conditions. It is felt that although its value is well known to the majority of surgeons, there are many problems w...
