Extracorporeal membrane oxygenation has been used successfully to support both cardiac and pulmonary function following Stage I Norwood operation. Determination of the return of native cardiac function and pulmonary function can be easily accomplished because of the single ventricle physiology. The pulmonary function can be assessed while on full flow ECMO by isolating the membrane oxygenator g...

Background: establishing a regular respiratory condition in the infants is one of the basic considerations in NICU.  Newborns show noticeable breath alterations in response to even low concentrations of some fragrance. Aim: determining the effect of breast milk odor on oxygen saturation and respiratory rate in premature infants. Methods: In this four-group randomized clinical trial, 180 prematu...

Background: The pandemic situation created an overwhelmed needs for ICU facilities, according to this problem, the need of accurate the management of facilities represents bold. In this study, prognostic risk factors for ICU admission among COVID-19 hospitalized patients were evaluated. Methods: From 22 February to April 20, 2020. Totally,214 COVID-19 patients participated in this study. The i...

In the past, near infrared spectroscopy (NIRS) has been mostly used to investigate oxidative metabolism in pathophysiology (Belardinelli et al., 1995; Ferrari et al., 1997). However, its application to exercise has increased exponentially over the past 15 years. NIRS is a noninvasive optical technology used to estimate tissue oxygenation by applying the physical principles associated with light...

Raised internal pressure in a distressed submarine rapidly increases the risk of decompression sickness (DCS) following submarine escape. The hypothesis that breathing a hyperoxic gas during escape may reduce the risk of DCS was tested using goats. Shallow air saturation and simulated submarine escape dives were carried out either singularly or in combination (saturation, escape, or saturation ...

This is a case series with chart review of 59 consecutive pediatric patients with a diagnosis of cervical esophageal coin who underwent anterior-commissure laryngoscope (ACLA) extraction during apnea. The purpose of this study was (1) to evaluate the efficacy and safety of coin extraction and (2) to analyze foreign body features and intraoperative physiological parameters (apnea time, O2 satura...

The patient was a 10-yr-old girl who was brought to the operating room to undergo appendectomy. Except for 1 week of abdominal pain and mild nausea but no vomiting, her history was negative. There were no previous anesthetics, environmental or drug allergies, recent upper respiratory infection, or reactive airway disease. No one in her household smoked. She weighed 62 kg and was 138 cm tall. Ex...

As liquid oxygen represents a relevant burden on healthcare systems, different methods have been developed to reduce oxygen consumption, including economizers. The aims of the study were: 1) to evaluate the efficacy of an economizer device (Companion 5 Oxygen Saver) in a significant sample of patients, and 2) to perform cost-minimization analysis of the possible savings to be obtained using the...

Whole body O2 uptake (VO2) during maximal and submaximal exercise has been shown to be preserved in the setting of beta-adrenergic blockade at high altitude, despite marked reductions in heart rate during exercise. An increase in stroke volume at high altitude has been suggested as the mechanism that preserves systemic O2 delivery (blood flow x arterial O2 content) and thereby maintains VO2 at ...

A significant reduction in arterial blood oxygen saturation during fiberoptic bronchoscopy has been proved but it is not yet known whether all patients need supplemental oxygen during this procedure. The aim of study is to examine the relationship between peak expiratory flow rate (PEFR) before bronchoscopy and oxygen desaturation during bronchoscopy. Measurement of PEFR (% predicted) performed...
