The purpose of study is the optimization of the choice of method of respiratory support in patients with severe community-acquired pneumonia (CAP) on admission to intensive care unit (ICU) on the basis of acid-alkaline indicators and arterial blood gas analysis. Material and methods. Depending on the method of the choice of respiratory support two groups of 350 people were formed. The first group (n = 350) - by the results of pulse oximetry (SatO2). The second group (n = 350) - in terms of acid-base and arterial blood gas analysis (pH, PO2, PCO2). To determine hypoxemia, pulse oximetry (heart monitor GOLDWAY G40), acid-alkali and gas composition of arterial blood (gas analyzer «MEDICA EasyStat») were used. In the ICU there were conducted three types of respiratory support: 1) oxygen therapy via orinasal mask 2) non-invasive mechanical ventilation (respirators «VENTimotion 2» and «Bipap Vision») 3) mechanical ventilation («Engstrom Carestation»). The criterion of effectiveness: recovery performance pulse oximetry, acid-base balance, and arterial blood gas analysis, the presence of positive clinical dynamics. Results. Choice of method of respiratory support in the gas composition of blood allowed to expand the indications for use NIV as a method of respiratory support in the treatment of patients with severe CAP, to ensure timely transfer and reduce the time finding patients on mechanical ventilation, to avoid damage due to hypoxia bodies - «target» with the development of multiple organ failure, and thus 4.3 times to reduce mortality and length of stay in the ICU of 1.7.

Purpose: Purpose of this report is to describe the feasibility of lingual pulse oximetry and lingual near-infrared spectroscopy (NIRS) in a COVID-19 patient to assess lingual tissue viability after several days of mechanical ventilation in the prone position. Materials & Methods: In a COVID-19 ICU-patient, the tongue became grotesquely swollen, hardened and protruding from the oral cavity after 20 h of mechanical ventilation uninterrupted in the prone position. To assess the doubtful viability of the tongue, pulse-oximetric hemoglobin O2-saturation (SpO2; Nellcor, OxiMax MAX-NI, Covidien, MA, USA) and NIRS-based, regional tissue O2-saturation measurements (rSO2; SenSmart, Nonin, MN, USA) were performed at the tongue. Results: At the tongue, regular pulse-oximetric waveforms with a pulse-oximetric hemoglobin O2-saturation (SpO2) of 88% were recorded, i.e. only slightly lower than the SpO2 reading at the extremities at that time (90%). Lingual NIRS-based rSO2 measurements yielded stable tissue rSO2-values of 76-78%, i.e. values expected also in other adequately perfused and oxygenated (muscle-) tissues. Conclusion: Despite the alarming, clinical finding of a grotesquely swollen, rubber-hard tongue and clinical concerns on the adequacy of the tongue perfusion and oxygenation, our measurements of both arterial pulsatility (SpO2) and NIRS-based tissue oxygenation (rSO2) suggested adequate perfusion and oxygenation of the tongue, rendering non-vitality of the tongue, e.g. by lingual venous thrombosis, unlikely. To our knowledge, this is the first clinical report of lingual rSO2 measurement.
