Experience Summary

In this series, the equipment in an intensive treatment unit (ITU) bed space are identified, and their features explained. In this 360° video, watch as the functions of the mechincal ventilator with a dry circuit are shown.

Clinical Context

Being correctly familiarised with the equipment found in an ITU bed space is essential for delivering safe, effective, and timely patient care. The ITU environment is highly complex, with critically ill patients relying on advanced technology to support vital organ function. A thorough understanding of this equipment enables healthcare professionals to respond confidently and appropriately in both routine care and emergency situations. Each ITU bed space typically contains equipment such as ventilators, infusion pumps, cardiac monitors, renal replacement therapy machines, suction devices, and oxygen delivery systems. Familiarity with how these devices operate, their alarms, and their limitations helps reduce the risk of user error, which can have serious or even fatal consequences. For example, misprogramming an infusion pump or failing to recognise a ventilator alarm may lead to delayed intervention and patient harm. Correct familiarisation also supports rapid decision-making. ITU patients can deteriorate quickly, and staff must be able to interpret monitor readings, troubleshoot equipment issues, and initiate immediate actions without hesitation. When clinicians are confident with the equipment, they can focus more fully on clinical assessment and patient-centred care rather than struggling with unfamiliar technology. In addition, proper equipment knowledge promotes effective teamwork and communication. ITU care is multidisciplinary, and a shared understanding of equipment use ensures smoother handovers, clearer communication during emergencies, and coordinated responses during procedures such as intubation or cardiac arrest. Finally, being familiar with ITU equipment supports infection prevention and equipment longevity. Knowing correct cleaning procedures, safe handling, and appropriate storage reduces the risk of healthcare-associated infections and equipment damage.

Mechanical Ventilator - Dry Circuit

A mechanical ventilator with a dry circuit is used to support or fully replace a patient’s breathing by delivering controlled oxygen and air without active humidification in the circuit. Instead, a heat and moisture exchanger (HME) is typically used at the patient interface to conserve heat and moisture from exhaled air. The ventilator allows precise control of parameters such as tidal volume, respiratory rate, pressure, and oxygen concentration. Dry circuits are commonly used in critical care as they reduce condensation, lower infection risk, and are simpler to set up and maintain.

Learning Outcomes

1. Be able to correctly identify the mechanical ventilator.
2. Be able to perform checks on the mechanical ventilator correctly.
3. Understand the components and functions of the mechanical ventilator.
