An apparatus and method for accomplishing simultaneous bronchoscopy and airway instrumentation and securing the instrument in place using an adjustable threaded gastight seal. The apparatus consisting of a hollow elongated manifold for simultaneous fiberoptic bronchoscopy through a fiberoptic port (4) and introduction a secondary tubular instrument (2) through a threaded secondary instrument port (5) while maintaining mechanical ventilation of a intubated patient using a ventilation port (7) and endotracheal tube connection port (6). The secondary instrument port (5) is constructed in a manner to allow introduction of a tubular instrument into the airway and form an adjustable gastight seal. It consists of a compressible perforated diaphragmatic seal (17) sandwiched between a threaded secondary instrument port and threaded perforated secondary instrument cap (18) so that the threaded cap may be torqued into the threaded secondary port (5) compressing the compressible diaphragmatic seal (17) against the inserted secondary instrument (2) forming airtight adjustable seal and affixing the secondary instrument in place. In addition, the secondary instrument port (5) allows chronic instrumentation following the removal of the fiberoptic bronchoscope (3) or reinspection.
