Description: Communication is a function dramatically altered during mechanical ventilation. Despite the large numbers of patients who require mechanical ventilation yearly, little has been done to examine their responses to being unable to speak during critical illness. The purpose of this descriptive correlational study was to prospectively examine the communication-related responses of mechanically ventilated patients. Specifically, this study examined the relationships among ventilated patients' emotional responses to being unable to speak, their perceived difficulty with communication and selected personal and situational variables: self esteem, severity of illness, race, the number of communication methods used, history of ventilation, reason for ventilation and the number of days ventilated. Interpersonal communication theory and the cognitive theory of emotion (Lazarus, 1966) provided the theoretical background and conceptual framework for the study. A convenience sample of 65 patients ranging in age from 18 to 80 participated in the study. Ventilated patients participated who were alert and oriented, able to communicate in English and ventilated for more than 24 hours. Patients' emotional responses to being unable to speak were measured by three subscales of the Emotion Scale (Folkman & Lazarus, 1988). Self esteem was measured using the Rosenberg Self Esteem Scale (Rosenberg, 1965). Subjects' perceived difficulty with communication and methods of communication were assessed with the investigator-developed Ease of Communication Scale and Methods of Communication Checklist, respectively.

Hierarchical multiple regression was used to examine the relationships between the emotional responses of anger, worry and confidence and the personal and situational variables. Self esteem, morbidity and perceived difficulty were significantly associated with patients' feelings of anger at being unable to speak. Patients expressed the most anger at being unable to speak who were more acutely ill, perceived more difficulty with communication, and had lower self esteem. Patients' perceived difficulty with communication and the number of days ventilated at data collection were significantly related to patients' feelings of worry at being unable to speak. The analysis showed that patients who were ventilated longer experienced less worry at being unable to speak, and patients who perceived communication to be the most difficult were the most worried at being unable to speak.
