Antibiotic resistance in respiratory pathogens

Current Opinion in Infectious Diseases, 1998
Antibiotic resistance in respiratory pathogens has dramatically increased during recent years. Resistance to penicillin and multiple antimicrobial agents in pneumococci and resistance to ampicillin in Moraxella catarrhalis and Haemophilus influenzae, as a result of betalactamase production, have become highly prevalent worldwide.

Effects of Obesity on Respiratory Resistance

Chest, 1993
To assess the effects of obesity on pulmonary function, 46 healthy subjects exhibiting various degrees of obesity underwent lung function tests. Subjects were divided into three groups according to body mass index (BMI): 13 had minimal obesity (BMI, 25 to 29 kg/m2, group 1); 24 had a BMI in the 30 to 40 range (group 2); and 9 displayed to morbid ...

Antimicrobial Resistance and Respiratory Infections

Chest, 2018
Since their introduction into health care and clinical practice in the early 20th century, antibiotics have revolutionized medicine. Alarmingly, these drugs are increasingly threatened by bacteria that have developed a broad diversity of resistance mechanisms.

Respiratory Resistance of Tracheostomy Tubes

Archives of Otolaryngology - Head and Neck Surgery, 1984
One of the main results of tracheostomy is to reduce the airflow resistance and power of breathing. The airflow dynamics of three types of commonly used tracheostomy tubes were studied. A generator was used to produce a sinusoidal airflow wave to simulate normal breathing.

Partitioning of Respiratory System Resistance in Children with Respiratory Insufficiency

American Journal of Respiratory and Critical Care Medicine, 1999
Abstract Using end-inspiratory airway occlusion, respiratory system resistance (Rrs) can be partitioned into a flow-resistive component (Rint), and an additional component ( Δ R), reflecting viscoelasticity and time constant inequalities.

Respiratory response to a decrease in velopharyngeal resistance

The Journal of the Acoustical Society of America, 1989
Individuals with congenital velopharyngeal impairment generally maintain adequate levels of intraoral pressures during consonant production by increasing respiratory effort. The purpose of the present study was to determine if normal individuals respond to a decrease in velopharyngeal resistance in a similar way.

Antibiotic Resistance in Nosocomial Respiratory Infections

Clinics in Laboratory Medicine, 2014
Nosocomial respiratory infections are the most common acquired infections in patients with severe underlying conditions and are responsible for high morbidity and mortality in this patient population. Multidrug-resistant (MDR) pathogens are associated with hospital-acquired pneumonia (HAP) and ventilator-associated pneumonia (VAP).

Resistance to respiratory airflow of the extrapulmonary airways

The Laryngoscope, 1993
AbstractResistances to respiratory airflow of nasal, pharyngeal, laryngeal, and tracheobronchial airway segments were determined by computer processing of digitized differential pressure and flow signals in four healthy, awake, male adults seated and breathing spontaneously at rest, exclusively through decongested noses.

A new method for measurement of respiratory resistance

Journal of Applied Physiology, 1983
A new method for measuring the resistance of the total respiratory system is presented. The method uses a device comprising a solenoid valve, a multiperforated plate, and a pneumotachograph. The multiperforated plate serves as a constant resistor (Rk) that is used to partially occlude the airway opening, thus rapidly and briefly reducing airflow ...
