Synchronized nasal intermittent positive pressure ventilation (SNIPPV) is noninvasive respiratory support that delivers ventilator breaths via the nasal prongs.We hypothesized that SNIPPV is more effective than nasal continuous positive airway pressure (NCPAP) in premature neonates due to decreased work of breathing (WOB). Fifteen infants (BW: 1,367 325 g, GA: 29.5 2.4 weeks) were studied on (a...

Transcutaneous PO2, heart rate, and aortic blood pressure were measured i 10 mechanically-ventilated newborn infants to assess the degree and course of hypoxaemia, and to monitor the cardiovascular and respiratory changes during tracheal toilet. Five infants weighed less than 1250 (mean 994), g and 5 infants weighed greater than 1750 (mean 2216) g. During tracheal suction the TcPO2 fell from 68...

A 21-year-old Mexican man was admitted to University Hospital with a six-month history of fever, cough, weight loss, and increasing shortness of breath. A family member had had isoniazid-resistant pulmonary tuberculosis. The physical examination showed cachexia, temperature of 38-3°C, blood pressure 95/65 mm Hg, clubbing, amphoric breath sounds over the left upper lobe, and wheezes over the res...

Acute exacerbation of chronic obstructive pulmonary disease (COPD) requiring invasive mechanical ventilation (IMV) is associated with a very poor prognosis. Therefore noninvasive mechanical ventilation (NIV) with avoidance of endotracheal intubation should be preferred. However, NIV can fail and result in severe respiratory acidosis. If IMV becomes mandatory, the development of pulmonary dynami...

BACKGROUND Intrapulmonary shunt as a result of atelectasis following cardiac surgeries is an important and common postoperative complication that results into pulmonary dysfunction typically lasting more than a week following surgery. Different methods have been provided to prevent these complications. OBJECTIVES In order to prevent postoperative pulmonary complications, investigation of the ...

Background: Humidified heated high flow nasal cannula (HHHFNC), nasal continuous positive airway pressure (NCPAP), and nasal intermittent positive pressure ventilation (NIPPV) are three nasal non-invasive ventilation methods. The purpose of this study was to compare these three methods in decreasing intubation and mechanical ventilation rate in preterm neonates with respiratory distress syndrom...

A newborn baby receiving mechanical ventilation was noted to have an extremely variable degree of hypoxia, despite the administration of 100% oxygen. The hypoxia was relieved rapidly when mechanical ventilation was withdrawn.
