An inspiratory force adapter designed to be connected between a tracheostomy tube and an inspiratory pressure gauge, comprising a hollow plastic body adapted to be grasped by the thumb and finger of the operator and having a finger port adapted to be closed by another finger of the operator when the inspiratory force of a patient is to be measured. The plastic body is provided with finger positioning surfaces so located as substantially to eliminate undesirable twisting motions of the adapter under the forces exerted by the operator's fingers.
