[ESTIMATION OF GAS EXCHANGE IN PATIENTS WITH COMMUNITY-ACQUIRED PNEUMONIA DURING NON-INVASIVE VENTILATION]
Abstract:
The problem of respiratory support due to pneumonia, complicated by severe respiratory failure, both in Ukraine and worldwide is very complex and challenging. More than half of the critical ICU patients undergoing mechanical ventilation, develop nosocomial infection, which can be avoided by using non-invasive ventilation (NIV). But its use in pneumonia is unclear. The aim of the study was to assess the parameters of gas exchange in patients with severe community-acquired pneumonia who were conducted non-invasive ventilation. NIV was performed in 18 patients with severe community-acquired pneumonia. At different stages of respiratory support blood gas analysis was perfodrmed. A statistically significant (P < 0.05) increase in the partial pressure of oxygen in arterial blood was observed during NIV compared to spontaneous breathing--(74.30 ± 18.51) mm Hg vs (47.20 ± 10.46) mm Hg. The mean value of hemoglobin oxygen saturation of arterial blood during spontaneous breathing was (80.4 ± 9.9)%, in the same group with NIV support the value was (94.5 ± 2.6)% (P < 0.05). NIV did not significantly affect the elimination of carbon dioxide and pH levels. NIV in patients with respiratory failure due to severe community-acquired pneumonia ensured adequate gas exchange parameters.

Assessment of Ventilation I: Respiratory Rate
A Ventilation assessment is critical for monitoring a patient's health status. Respiration, one of the most accessible vital signs, provides insights into the function of numerous body systems and can indicate serious health issues, such as brainstem injuries from head trauma.
Critical Guidelines for Assessing Ventilation:
Respiratory Volumes and Capacities
Assessment of Diffusion and Perfusion
The Role of Diffusion in Respiration
Diffusion is the process by which molecules move from an area of higher concentration to an area of lower concentration. In the respiratory system, this...
Assessment of Ventilation II: Respiratory Depth and Rhythm
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:
