Mechanical ventilation is a common therapeutic modality required for the management of patients unable to maintain adequate intrinsic ventilation and oxygenation. Mechanical ventilators can be found within various hospital and nonhospital environments (ie, nursing homes, skilled nursing facilities, and patient's home residence), but these devices generally require the skill of a multidisciplinary health care team to optimize therapeutic outcomes. Unfortunately, pharmacists have been excluded in the discussion of mechanical ventilation since this therapeutic modality may be perceived as irrelevant to drug utilization and the usual scope of practice of a hospital pharmacist. However, the pharmacist provides a crucial role as a member of the multidisciplinary team in the management of the mechanically ventilated patient by verifying accuracy of prescribed medications, providing recommendations of alternative drug selections, monitoring for drug and disease interactions, assisting in the development of institutional weaning protocols, and providing quality assessment of drug utilization. Pharmacists may be intimidated by the introduction of advanced ventilator microprocessor technology, but understanding and integrating ventilator management with the pharmacotherapeutic needs of the patient will ultimately help the pharmacist be a better qualified and respected practitioner. The goal of this article is to assist the pharmacy practitioner with a better understanding of mechanical ventilation and to apply this information to improve delivery of pharmaceutical care.
