Identifying hypotension

You can do this in various ways:

Direct measurement of arterial blood pressure using a catheter placed in a peripheral artery is the most accurate way to determine blood pressure but is not necessarily the most practical way. In a few practices with a high volume of critical patients, direct arterial blood pressure measurement might be appropriate. However, for most practices, the technique is too time-consuming and cumbersome and is not necessary in most patients. The exception is surgical equine practice. All horses anesthetized with inhalant anesthesia should be monitored using direct arterial blood pressure.Doppler – provides audible indication of blood flow (comforting!), can be used for monitoring heart rate and for determining blood pressure (systolic – so maintain above 90 mmHg). This is my absolute favorite monitor for the price (relatively inexpensive) and utility (extremely useful). However, the monitor does take a bit of work to set up (shave the skin, appropriately place the probe, tape on the probe, manually measure blood pressure) and some experience to use the unit well. TIP: We are underutilizing this tool! Use for measuring blood pressure in anesthetized patients, in patients with hypertensive disease (eg, renal disease, hyperthyroidism, etc.) and in patients with likelihood of hypotension (eg, hypothyroidism or shock from trauma, etc.). Use for heart rate in exotic species – works great in pocket pets, birds, snakes, etc. All you have to do is find an artery!Oscillometric blood pressure monitors – these units are easier to use than Dopplers (just put the cuff on and press start) and generally provide consistent readings in medium to large patients. However, readings may not be consistent in small patients (eg, cats), patients with arrhythmias, patients that are moving (or shivering) and extremely hypotensive patients. Thus, having a Doppler AND an oscillometric unit is often a wise choice.Recommendation: Every c...
