You determine that an acutely ill patient can generate an MIP of -18 cm H₂O. Based on this information, what might you conclude? A) The patient has inadequate respiratory muscle strength. B) The patient has inadequate alveolar ventilation. C) The patient has an excessive work of breathing. D) The patient has an unstable or irregular ventilatory drive.

An MIP (maximum inspiratory pressure) value of F1F1F1S1F1F1F1018 cm H2O indicates that the patient has inadequate respiratory muscle strength. MIP is a measure of the maximum pressure generated by inspiratory muscles during a forced inspiratory maneuver. A low MIP value indicates that the patient is unable to generate adequate negative pressure to overcome the resistance of the airway and inflate the lungs adequately. This is often seen in patients with respiratory muscle weakness due to neuromuscular disease, chronic obstructive pulmonary disease (COPD), or other conditions that impair respiratory muscle function.
