Final answer:
The maximum amount of suction time in tracheobronchial suctioning is around 10-15 seconds to prevent complications and minimize damage to the airway mucosa.
Step-by-step explanation:
The maximum amount of suction time when performing tracheobronchial suctioning varies depending on the specific situation and the patient's condition. Generally, the suction time should be kept as short as possible to minimize the risk of complications. However, it is recommended to limit the suction time to around 10-15 seconds to prevent excessive suctioning that can damage the airway mucosa and cause irritation.
