Cases: Case 1: A 63-year-old woman was referred for coughing blood. Although cardiorespiratory dynamics were stabilized by artificial respiration under sedation, severely poor ventilation developed from asphyxia associated with massive respiratory tract hemorrhage. One-lung ventilation was temporarily secured by endotracheal tube insertion into the left main bronchus just prior to cardiopulmonary arrest.Case 2: A 72-year-old man was referred for massive hemoptysis after coughing, then intubated and placed on a respirator...

The effects of hypoxic, hyperoxic, and hypoxic-hyperoxic preconditioning were examined in the prospective study on narcotized and artificially ventilated rabbits. Under artificial circulation, acute myocardial ischemia was modeled by ligation of anterior descending coronary artery, which was followed by reperfusion. The degree of ventricular arrhythmias was assessed, and the ischemic area was evaluated in percent of the area at risk. Microscopic characterization of the myocardium was employed to assess the cardioprotective effect of hypoxic and/or hyperoxic preconditioning...

In mechanical ventilation, in particular when neonates are ventilated, it is crucial to accurately control the amount of the gas delivered to the patients. Mechanical ventilators are equipped with one of more flowmeters. The signal of the flowmeter is used as feedback to control the amount of gas delivered to the patients. Therefore, the accuracy of the flowmeter plays a crucial role in the accurate adjustment of the gas amount delivered by the ventilator. Among several solutions, variable area orifice meters (VAOMs) have several valuable features (e...

We tested the hypothesis that carotid chemoreceptors tune breathing through parallel circuit paths that target distinct elements of an inspiratory neuron chain in the ventral respiratory column (VRC). Microelectrode arrays were used to monitor neuronal spike trains simultaneously in the VRC, peri-nucleus tractus solitarius-medial medulla (p-NTS-MM), the dorsal parafacial region of the lateral tegmental field (FTL-pF), and medullary raphé nuclei together with phrenic nerve activity during selective stimulation of carotid chemoreceptors or transient hypoxia in 19 decerebrate, neuromuscularly-blocked, and artificially ventilated cats...

A 9-month-old female Weimaraner was presented to the emergency service due to episodes of fever and neck pain. Physical examination revealed a stiff neck posture and elevated body temperature. Shortly after clinical examination was performed, the dog developed peracute onset of non-ambulatory tetraparesis compatible with a C1-C5 spinal cord (SC) lesion. Immediately thereafter (<1 h), MRI of the cervical SC was performed with a 3-T scanner. A left ventrolateral intradural-extramedullary SC compression caused by a round-shaped structure at the level of C3--C4 was evidenced...

A 66-year-old man with a several year history of thrombocytopenia, pleural effusion and ascites, anasarca, and organomegaly presented with general fatigue, appetite loss, dyspnea with type II respiratory failure. The precise history of the patient and the re-evaluation of lymph node and bone marrow biopsies conducted by the previous physician indicated TAFRO syndrome. The patient's laboratory data improved for a year with tocilizumab, but then worsened to the point that the patient required artificial ventilation due to the deterioration of type II respiratory failure...

Ventilator-associated pneumonia (VAP) is a healthcare-acquired infection arising from the invasion of the lower respiratory tract by opportunistic pathogens in critically ill ventilated patients. The current method of diagnosis requires the culture of an airway sample such as bronchoalveolar lavage, which is invasive to obtain and may take up to seven days to identify a causal pathogen, or indeed rule out infection. While awaiting results, patients are administered empirical antibiotics; risks of this approach include lack of effect on the causal pathogen, contribution to the development of antibiotic resistance and downstream effects such as increased length of intensive care stay, cost, morbidity and mortality...

An artificial placenta (AP) using venovenous extracorporeal life support (VV-ECLS) could represent a paradigm shift in the treatment of extremely premature infants. However, AP support could potentially alter cerebral oxygen delivery. We assessed cerebral perfusion in fetal lambs on AP support using near-infrared spectroscopy (NIRS) and carotid arterial flow (CAF). Fourteen premature lambs at EGA 130 days (term = 145) underwent cannulation of the right jugular vein and umbilical vein with initiation of VV-ECLS...

Mechanical ventilation is regarded as an effective means of replacing artificial ventilation during cardiopulmonary resuscitation (CPR), and has been widely used in the treatment of cardiac arrest (CA) patients. However, there are still some controversial issues remaining to be settled, such as the assessment of the effectiveness of mechanical ventilation, the selection of the optimal oxygen concentration (FiO2), tidal volume (VT), respiratory frequency, and mode of ventilation during the CPR process. The pros and cons of positive pressure ventilation are also inconclusive...

BACKGROUND: Invasive ventilation is used to assist or replace breathing when a person is unable to breathe adequately on their own. Because the upper airway is bypassed during mechanical ventilation, the respiratory system is no longer able to warm and moisten inhaled gases, potentially causing additional breathing problems in people who already require assisted breathing. To prevent these problems, gases are artificially warmed and humidified. There are two main forms of humidification, heat and moisture exchangers (HME) or heated humidifiers (HH)...
