RespirAq Humidifier Usability During Invasive Ventilation

RespirAq Humidification During Post-operative Invasive Mechanical Ventilation in Scheduled Cardiothoracic Surgical Patients: a Feasibility Study

This study aims to capture preliminary safety and effectiveness information on a near-final humidifier device design and to provide data for more extensive research, if required. This feasibility study will investigate the following: process, resources, management, and scientific aspects of delivering humidification by the RespirAq humidifier device in ventilated patients.

Inclusion Criteria:

Patients scheduled for coronary artery bypass surgery (CABG) will be recruited before their surgical procedure at the Waikato district health board during February, March, and April of 2021.

Exclusion Criteria:

• Age <18 years
• Have any other condition which, at the investigator's discretion, is believed may present a safety risk or impact the feasibility of the study or the study results
• Patients admitted for emergency CABG surgery
• Unable to provide written informed consent before surgery
• Patients who would be contra-indicated to HME humidification devices
