Step-by-step explanation:
The therapist should FIRST check the ventilator circuit for disconnections or leaks.
Checking the ventilator circuit for disconnections or leaks should be the first step because it ensures that the equipment is functioning correctly before proceeding with other interventions.
For example, if there are disconnections or leaks in the ventilator circuit, it could lead to ineffective delivery of oxygen and compromised lung function. Therefore, addressing this issue first is essential in providing proper ventilation to the patient.
