ICU Respiratory Support: Helping Patients with Breathing Difficulties

The ICU provides comprehensive care for critically ill patients. When patients cannot breathe independently, various respiratory support methods are used:

Mechanical Ventilation

• Endotracheal Intubation: Tube through mouth/nose into trachea for direct oxygen delivery.
• Tracheostomy: Surgical neck incision for long-term ventilation.
• Oxygen Therapy: Supplemental O2 via nasal cannula, face mask, or ventilator.

Non-Invasive Ventilation

• CPAP: Constant positive pressure via mask to keep alveoli open.
• BiPAP: Two pressure levels (inhale/exhale) to support respiratory effort.

Mechanical Ventilators

Advanced ventilators assist or fully control breathing with adjustable settings. ICU teams continuously monitor vitals, blood gases, and respiratory effort to optimize settings.

Monitoring and Management

• Pulse Oximetry: Continuous SpO2 monitoring.
• Arterial Blood Gas Analysis: Regular O2, CO2, pH measurement.
• Capnography: Exhaled CO2 monitoring for ventilation assessment.

ICU respiratory care requires expertise, coordination, and teamwork among pulmonologists, intensivists, and critical care nurses for personalized support and complication management.
