Radial pulse being slower than heart rate?

Is it possible to have a slower radial pulse than your actual heart rate. Someone told me it was, but I can't understand how this would be possible!!! Could someone enlighten me, as I can't understand why this would ever occur.

Open cardiac massage in asthmatic arrests? |

This idea was provoked by a colleague some years ago who could not achieve a palpable pulse during CPR of an arrested asthmatic child. He wondered whether the severe hyperinflation was rendering external cardiac compressions ineffective and whether he should have done a (prehospital) thoracotomy.

You have just intubated a 65 year old woman with sudden respiratory failure. On arrival, she had a pulse but cool extremities. She was obtunded and agonal with SpO2 was in the high 70’s. After pre-oxygenating with BVM to 100%, the intubation went smoothly. You had a clear view of the cords and passed a cuffed 8-0 through easily with qualitative capnography and bilateral breath sounds. Now, post-intubation, her SpO2 is 86% and steadily dropping.

5 y/o F presents to the ED feeling “uneasy.” She is noted to have a pulse of 140 and BP of 180/110 and is profusely sweating. She is on imipramine for bedwetting, no other PMH. Pupils are PERRL. Exam is otherwise unremarkable. CBC, BMP, UA are negative. When considering a toxidrome, what is your differential?

Fracture Fridays: Getting a leg up on the competition (Re-post)

An 80 pound 12 year old soccer star tripped in a hole while challenging for the ball. Another player on the pitch stumbled in the same (big) hole and landed awkwardly on the first player’s leg. Even the fans on the next field over heard the snap. EMS was called and an obviously uncomfortable 12 year old male with intact distal foot pulses and sensation presents to your ED. You do what you normally do and get an X-Ray.

Routine compared with selective ultrasound in early pregnancy | Cochrane

Ultrasound is an electronic technology that uses the reflection of pulses of high-frequency sound to produce an image. Ultrasound may be used in a variety of circumstances during pregnancy. It has been assumed that the routine use of ultrasound in early pregnancy will result in the earlier detection of problems and improved management of pregnancy complications when compared with selective use for specific indications such as after clinical complications (e.g. bleeding in early pregnancy), or where there are concerns about fetal growth.

Critical Care

Pulse oximetry is universally used for monitoring patients in the critical care setting. This article updates the review on pulse oximetry that was published in 1999 in Critical Care. A summary of the recently developed multiwavelength pulse oximeters and their ability in detecting dyshemoglobins is provided. The impact of the latest signal processing techniques and reflectance technology on improving the performance of pulse oximeters during motion artifact and low perfusion conditions is critically examined. Finally, data regarding the effect of pulse oximetry on patient outcome are discussed.

Transcranial magnetic stimulation (TMS) for the treatment of schizophrenia | Cochrane

Transcranial magnetic stimulation is a relatively new and sophisticated device-based therapy. TMS involves the skilful application of a strong magnetic field close to the surface of the scalp. The TMS device delivers strong and very brief magnetic pulses that stimulate the brain and its network of neurons. TMS is a relatively painless and non-invasive technique that stimulates parts of the brain (the cerebral cortex). Brain activity has been shown to differ in people with schizophrenia compared to other people.

Interventions for renal vasculitis in adults | Cochrane

Renal vasculitis presents as rapidly progressive glomerulonephritis which is a form of kidney disease that causes damage to the small structures (glomeruli) inside the kidneys that help filter waste and fluids from blood to form urine. The disease leads to a rapid loss of kidney function. Standard suppression of the immune system with steroids and cyclophosphamide is recommended. The aim of this review was to evaluate the benefits and harms of any intervention for the treatment of renal vasculitis. Thirty one studies (2217 patients) were identified. Plasma exchange reduces the risk of end-stage kidney disease in patients presenting with severe acute kidney failure. The use of pulse cyclophosphamide results in good remission rates but there was an increased risk of relapse. Azathioprine is effective as maintenance therapy once remission has been achieved. Mycophenolate mofetil is equivalent for remission induction than cyclophosphamide. Mycophenolate mofetil has also been tested in maintenance treatment and was found to result in a higher rate of disease relapse. Initial data on rituximab showed equivalent effectiveness to cyclophosphamide. Methotrexate and leflunomide are useful in maintenance therapy but their relative effectiveness are not clearly defined. Treatment with co-trimoxazole may prevent respiratory infections and relapses but are unlikely to have a major impact on systemic relapses of vasculitis.

Pulse oximeters used to self monitor oxygen saturation levels as part of a personalised asthma action plan for people with asthma | Cochrane

We became aware through talking with people with asthma that some are using pulse oximeters to monitor their own blood oxygen levels during an asthma attack. Pulse oximeters are marketed by some suppliers as essential equipment for the home medicine cabinet. We wanted to find out if reliable evidence is available on use of pulse oximeters to self monitor asthma exacerbations at home. We decided to include only trials that used pulse oximeters as part of a personalised asthma action plan because it is important that decisions are made on the basis of symptoms as well as oxygen saturation, and that patients have a clear protocol to follow when their asthma worsens.

Rescue high-frequency jet ventilation versus conventional ventilation for severe pulmonary dysfunction in preterm infants | Cochrane

Background: In very low birth weight infants who require support on breathing machines (ventilators), ventilator-associated lung injury and toxic effects of oxygen may be important factors in creating a chronic disturbance in lung function. Compared with routine conventional ventilators, high-frequency jet ventilators (breathing machines that introduce short-duration pulses of gas under pressure into the airway at a very fast rate) may reduce the severity of lung injury associated with mechanical ventilation.
