As a CNA in the ICU, your responsibilities commonly include assisting patients with daily living activities, monitoring vital signs, helping with repositioning or transferring patients, and promptly reporting changes in patient condition to registered nurses. You may also help maintain a sterile environment, keep patient rooms stocked, and provide emotional support to patients and their families. Collaboration with nurses and physicians is a key part of the role, as patient needs in the ICU can change rapidly. The fast-paced atmosphere requires CNAs to be detail-oriented and adaptable, as you'll be directly supporting the clinical team in providing high-level, attentive care.
