Abstract:
The double T-piece breathing system is described. The Bird Ventilator Mark 2 is utilised as an oxygen pressure jet to drive an injector placed at the distal end of the double T-piece breathing system. An active anti-pollution assembly is employed. Both the double T-piece breathing system and the anti-pollution assembly are valveless. The injector's design is described. The ventilator functioned properly at 1.8 m distance from 1.5 tesla electromagnet without degrading its imaging. The Bird ventilator, the injector, and the double T-piece breathing system are small in size, easy to handle, and can be used for paediatric and adult patients.

Radiological Investigation II: MRI and Ventilation Perfusion Scan
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
Oxygen Delivering System III: Tracheostomy and T-piece
Tracheostomy
A tracheostomy is a surgically created opening (stoma) in the anterior part of the trachea. It is used to establish a patient airway, bypass an upper airway obstruction, simplify the removal of secretions, permit long-term...
Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...
