Figure 1: The patient´s chest X-ray before intubation showing bilateral pneumonia, atelectasis, and severe scoliosis with a Harrington rod (A). The patient after intubation – Infrared Red Intubation System placed on outer trachea (B). The patient after extubation, demonstrating maximal mouth opening of 13 mm (C).
Figure 2: Flexible bronchoscope view of a normal airway in a healthy man (43 years; 195 cm; 90 kg).
Upright sitting position with optimal airway diameter.Additional maneuvers for optimising visibility of relevant structures (since vocal cord movements or air bubbles may become visible): Normal breathing (A.1), ´take a deep breath´ (A.2), Valsalva maneuver (A.3) and ´say eee´ (A.4).
Supine position with partial airway collapse. Maneuvers for optimising airway diameter: Normal breathing (B.1), ´stick out tongue´ (B.2), ´jaw thrust´ (B.3) and continuous positive airway pressure with high-flow nasal oxygenation with maximal flow (B.4).
Infrared Red Intubation System (IRRIS). For optimising visibility of relevant structures: Turned off (C.1), turned on – normal breathing (C.2), turned on – deep breath (C.3) and seen from the outside - placed on upper trachea (C.4).
