In other series from Europe, the rate of decline in FEV1 was considerably higher, estimated at approximately 100 to 120 mL/yr. [6] [129] [130] In the MILES trial, patients in the placebo group lost 134 cc/yr. [35] There was some evidence in these studies that rate of decline in lung function correlates with initial DLCO, with menopausal status ...
CPR involves chest compressions for adults between 5 cm (2.0 in) and 6 cm (2.4 in) deep and at a rate of at least 100 to 120 per minute. [2] The rescuer may also provide artificial ventilation by either exhaling air into the subject's mouth or nose ( mouth-to-mouth resuscitation ) or using a device that pushes air into the subject's lungs ...
A RSBI score of less than 65 [3] indicating a relatively low respiratory rate compared to tidal volume is generally considered as an indication of weaning readiness. A patient with a rapid shallow breathing index (RSBI) of less than 105 has an approximately 80% chance of being successfully extubated, whereas an RSBI of greater than 105 virtually guarantees weaning failure.

An open circuit SCBA typically has three main components: a high-pressure gas storage cylinder, (e.g., 2,216 to 5,500 psi (15,280 to 37,920 kPa), about 150 to 374 atmospheres), a pressure regulator, and a respiratory interface, which may be a mouthpiece, half mask or full-face mask, assembled and mounted on a framed carrying harness.
Lower respiratory tract infection (LRTI) is a term often used as a synonym for pneumonia but can also be applied to other types of infection including lung abscess and acute bronchitis. Symptoms include shortness of breath , weakness, fever , coughing and fatigue. [ 3 ]
An analysis of 2024 Google search data revealed the top health questions asked by Americans. A registered nurse provides answers to the seven most common inquiries.
The tone of respiratory muscle is believed to be modulated by muscle spindles via a reflex arc involving the spinal cord. Drugs can greatly influence the rate of respiration. Opioids and anesthetics tend to depress ventilation, by decreasing the normal response to raised carbon dioxide levels in the arterial blood.
