System Components and Device Types

This section describes the major categories of respiratory equipment used in clinical practice. Intensive care ventilators provide full support for patients with severe respiratory failure and include advanced monitoring and safety features. Transport ventilators are designed for durability and battery powered operation during patient movement. High flow nasal cannula systems deliver heated and humidified oxygen at high flow rates to improve oxygenation and reduce work of breathing. Noninvasive ventilators provide pressure support through masks and are used for acute and chronic respiratory failure. Oxygen delivery devices include nasal cannulas, simple masks, venturi masks, and nonrebreather masks. Airway adjuncts include oral airways, nasal airways, and supraglottic devices. Monitoring devices include pulse oximeters, capnography systems, and transcutaneous monitors.

Key Technical Concepts

This section provides accessible explanations of essential respiratory care concepts. Ventilator modes determine how breaths are delivered and how pressure and volume are controlled. Tidal volume selection influences lung protection and gas exchange. Pressure control strategies help limit barotrauma. Positive end expiratory pressure maintains alveolar recruitment and improves oxygenation. Fraction of inspired oxygen must be titrated to avoid oxygen toxicity. Leak compensation is important for noninvasive ventilation. Humidification supports secretion management and patient comfort. Alarm logic ensures early detection of unsafe conditions. The section explains how parameter choices influence gas exchange, patient comfort, and clinical outcomes.

Routine Equipment Checks

This section provides a detailed checklist for daily and periodic equipment checks. Circuit integrity must be verified to prevent leaks and ensure accurate ventilation. Battery checks are essential for transport ventilators and emergency preparedness. Filters must be inspected and replaced according to infection control policies. Calibration verification ensures accurate monitoring of pressure, volume, and flow. Software updates and service events must be documented to maintain compliance and equipment readiness. The section also explains how to coordinate with biomedical engineering and how to document checks in the medical record.
