“…Typical values of tidal volume are in the range of 1-3 ml/kg bodyweight; a volume that represents about 50% or less of the anatomical dead space. Correspondingly, ventilation frequencies are increased to 5-15 Hz, depending on the patients age (Rimensberger et al, 2015). Despite such low tidal volumes HFOV is known to sustain sufficient oxygenation and CO 2 elimination (Imai et al, 2001; IStachow, 1995), both of which strongly depend on the adequate combination of ventilation frequency, tidal volume and mean airway pressure (MAP).…”

“…A hypothesis determined before the experiment indicates that a negative impact on the animal model's physiological parameters using a pressure orifice plate (flow sensor) at high-frequency jet ventilation is expected. This assumption is given mainly because the phenomenon of permanent pressure loss in these flow sensors is known in the literature [6,7,11,12] and confirmed by the work [8,9]. On the other hand, the described experiments showed that all observed negative manifestations (decrease in pressure amplitude in the lung model and deterioration of CO2 elimination) could be compensated for by increasing the jet breath's pressure amplitude using the PIP parameter.…”

High-frequency jet ventilators lacking flow monitoring systems, and information about supplied tidal volumes are still missing. This complicates the jet ventilator’s initial setting; at the same time, it complicates the line of the high-frequency ventilation itself. Therefore, an experimental flow sensor (orifice plate) was designed and placed in the ETC (endotracheal tube). Laboratory tests have confirmed the solution’s functionality, but it was necessary to verify the practical applicability for the clinical environment. The experiment shows that the flow sensor is used only for research purposes or when using functional monitoring of chest excursions.

“…To prevent associated morbidity and mortality, timely detection and treatment of these events is crucial 3 . On the other hand, congenital anomalies and illnesses in term infants can also lead to respiratory instability, and thus require cardiorespiratory monitoring as well 4 . Monitoring is currently performed by measuring heart rate (HR) with electrocardiography (ECG) and respiratory rate (RR) with chest impedance (CI), using three wired adhesive electrodes.…”

IntroductionWe determined if the heart rate (HR) monitoring performance of a wireless and nonadhesive belt is non‐inferior compared to standard electrocardiography (ECG). Secondary objective was to explore the belt's respiratory rate (RR) monitoring performance compared to chest impedance (CI).MethodIn this multicenter non‐inferiority trial, preterm and term infants were simultaneously monitored with the belt and conventional ECG/CI for 24 h. HR monitoring performance was estimated with the HR difference and ability to detect cardiac events compared to the ECG, and the incidence of HR‐data loss per second. These estimations were statistically compared to prespecified margins to confirm equivalence/non‐inferiority. Exploratory RR analyses estimated the RR trend difference and ability to detect apnea/tachypnea compared to CI, and the incidence of RR‐data loss per second.ResultsThirty‐nine infants were included. HR monitoring with the belt was non‐inferior to the ECG with a mean HR difference of 0.03 beats per minute (bpm) (standard error [SE] = 0.02) (95% limits of agreement [LoA]: [−5 to 5] bpm) (p < 0.001). Second, sensitivity and positive predictive value (PPV) for cardiac event detection were 94.0% (SE = 0.5%) and 92.6% (SE = 0.6%), respectively (p ≤ 0.001). Third, the incidence of HR‐data loss was 2.1% (SE = 0.4%) per second (p < 0.05). The exploratory analyses of RR showed moderate trend agreement with a mean RR‐difference of 3.7 breaths/min (SE = 0.8) (LoA: [−12 to 19] breaths/min), but low sensitivities and PPV's for apnea/tachypnea detection. The incidence of RR‐data loss was 2.2% (SE = 0.4%) per second.ConclusionThe nonadhesive, wireless belt showed non‐inferior HR monitoring and a moderate agreement in RR trend compared to ECG/CI. Future research on apnea/tachypnea detection is required.
