Miniaturization of electronics over the years has resulted in a small two-piece device used in cochlear implants.
The one-piece device is 360 μm in length, and the maximal width of the conical head is 230 μm.
The T-piece device had a higher stress response than PSV and CPAP modes after weaning off mechanical ventilation.
Alveolar air was collected using a Y-piece device (QuinTron AlveoSampler) after 10 seconds' expiration, analysed immediately after the collection and corrected for alveolar CO2.
Manual ventilation using a T-piece device allows better control of PIP, use of PEEP and probably less variation in pulmonary ventilation.
The authors conclude that the use of a T-piece device allows lower variability during manual ventilation, with the exception of respiratory rate and expiratory time.
Adult New Zealand White rabbits were manually ventilated by 21 individuals using a self-inflating bag (LIFESAVER® Neonate Manual Resuscitator; Teleflex Medical, Research Triangle Park, NC, USA) or a T-piece device (Babypuff®; Fanem Ltd ,São Paulo, Brazil).
Cuffed Schnogh: Each set is a one-piece device designed as twistable by one hand, which is suitable for an arm lymphedema in those who are enthusiastic to do the care without assistant; twisting therefore is to be conducted by the hand of the unaffected side.
To compare using an experimental model with the adult rabbit, the variability of PIP, PEEP, Vt, minute ventilation (VMin), respiratory rate (RR), inspiratory time (Tins), expiratory time (Tex) and ratio Tins/Total time during manual ventilation using a self-inflating bag or T-piece device.
Two-piece devices: a female and a male part make up these devices.
The LP-ESP disc is a one-piece deformable device achieving 6 df, including shock absorption and elastic return.
