Abstract
Objective To explore the clinical value of airbag pressure gauge monitoring artificial airway cuff pressure.Methods 29 patients' cuff pressure was measured with airbag pressure gauge and experience method.The results between the two methods were compared.Results Among the 29 patients,27.59％ patients had higher pressure than ideal value,48.28％ lower,and only 24.14％ equal.The correlation between airbag pressure gauge and experience method was a low level of 0.469.The accuracy was 41.02％,the sensitivity 11.77％,the specificity 63.64％,the positive predict value 20.00％,and the negative predict value 48.28％ of experience method,P =0.140.Conclusions Measuring cuff pressure with experience method has a big error.Therefore,measuring cuff pressure regularly with airbag pressure gauge is recommended to ensure the safety of patients undertaking mechanical ventilation maintaining the cuff pressure within a safe range. Key words: Airbag pressure gauge; Cuff pressure; Artificial airway
